I.Description74LS138 is a 3-line to 8-line decoder/demultiplexer. The chip is designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In high-performance memory systems, these decoders can be used to minimize the effects of system decoding. The three enable pins of chip (in which Two active-low and one active-high) reduce the need for external gates or inverters when expanding.CatalogI. DescriptionII. Digital Voltmeter CircuitFAQOrdering & QuantityII. Digital Voltmeter CircuitWe use AD574 and AT89C2051 to form a high-precision digital voltmeter. The schematic diagram is shown in Figure 1. AD574  is a 12-bit successive comparison A/D converter with 12 data lines in total. P1 of AT89C2051  is directly connected to the high 8-bit data line of AD574,  The low 4-bit data line of AD574  is directly connected with the upper half 4-bit p1.4-p1.7 of single-chip microcomputer. Data reading is based on the control line of a single-chip microcomputer,  P3.5 is connected to AD574  byte short period control line (A0). P3.4 is connected to read conversion data control pin. And P3.7 is directly connected with the terminal of indicating working status (STS). Such structure determines that it can only be 8-bit output, so the data mode selection end can be directly grounded. AT89C2051  has only 15  I / O  port wires, 11 of which are used above, and only 4 of them are left. The output data is output through the serial port of the single-chip microcomputer.  and an external 74LS164  (serial in and parallel out) decoder is connected for expansion. At the same time, the data displayed is 4 bits, and the remaining 2 port lines still can not meet the requirements. A 74LS138 decoder is needed to gate the address of the display LED.Here we use the input mode of the 10V range. Pin13 of AD574  is the input terminal of the measured voltage. Because only one AD574  conversion chip is used, the CS terminal can be directly grounded. The converter uses ±12V power supply voltage and the working voltage is +5V.74LS164 is a serial input and parallel output decoder,  The BCD serial code output by AT89C2051 through the serial port is decoded by 74LS164  and output as a seven-segment  BCD code, which is directly connected to a-g of the LED, and the data lines of the four LEDs are connected one by one. LED digital tube uses a common anode type. The address code output by 74LS138 is connected to the common terminal of the LED via a transistor 2SA1015  (PNP). The display of the four-digit LED is a time-sharing strobe through the address line, which is our commonly used dynamic scanning display method.It is worth mentioning that in the dynamic scanning display mode, the frequency of dynamic scanning has certain requirements. If the frequency is too low, the LED will flicker. If the frequency is too high, the lighting time of each LED is too short, and the brightness of the LED is too low. It can’t be seen clearly with the naked eye. So it is generally appropriate to take about 10ms. This requires that when writing a program, a certain LED should be on and kept for a certain period of time. The program often uses the call delay subroutine.FAQWhat type of applications is 74LS138 designed to be used?High-performance memory-decoding or data-routing applicationsHow many pins does 74LS138 reduce the need for external gates or inverters when expanding?Three enable pinsWhat is a 74LS164?A serial input and parallel output decoder.What is the difference between 74hc138 and 74LS138?Both have the same function. 74HC138 is made of high-speed CMOS process, with low power consumption, high output, low level and wide range.74LS138 adopts the early bipolar process, and its driving capability is relatively larger.What is the functional difference between 74ls138 decoder and 74ls148？74ls138 is a 3-8 wire decoder/multiplexer, 74ls148 is an 8-3 wire octal priority encoder.One is decoding and the other is encoding. Opposite effectWhat's the difference between 74LS138D and 74LS138N？Those two are the same chip, D is SOP package, N is DIP package.What are the output characteristics of 74LS138 decoder？Under the premise that the enable terminals S1 (active high), S2 (active low), and S3 (active low) are valid at the same time, only one output terminal is low at a time (the rest are high);If the enable terminal is invalid, the output is all high level.What do the letters and numbers in 74ls138 stand for？74ls138 is a 3-8-line decoder. The number 74 represents the 74 series of the 54/74 series, and the 74 series has an operating temperature of 0 degrees to 70 degrees. LS is a series, representing the low-power Schottky series. 138 is the variety code.What’s the working principle of 74ls138?74LS138 working principle① When one strobe terminal (E1) is high level, and the other two strobe terminals (E2) and (E3) are low level, at the output terminals corresponding to Y0 to Y7, the binary code of address terminals (A0, A1, A2)  can be decoded at low level. For example: when A2A1A0=110, the Y6 output terminal outputs a low-level signal.②Using E1, E2 and E3, it can be cascaded to expand into a 24-line decoder; if an external inverter is connected, it can also be cascaded to expand into a 32-line decoder.③If one of the strobe terminals is used as a data input terminal, 74LS138 can also be used as a data distributor.④It can be used in 8086 decoding circuit to expand memory.

I. IntroductionThe 74HC595 is an 8-bit serial-in or parallel-out shift register with a storage register and 3-state outputs. 74HC595 with the characteristics of high speed, low power consumption, and simple operation, can be easily used in the MCU interface to drive LED  operation. This article introduces the circuit design of LED displays driven by 74HC595.CatalogI. IntroductionII. Basic Description2.1 LED Display2.2 74HC595III. Circuit Design3.1 Hardware Circuit3.2 Display DriverIV.  ConclusionFAQOrdering & QuantityII. Basic Description2.1 LED DisplayA 7 Segment LED Display, also known as an LED  display, has been widely used in various instruments because of its low price, low power consumption, and reliable performance. There are many types of LED  drivers on the market, and most of them have multiple functions, but the price is correspondingly higher. If used in a simple system with low cost, it is not only a waste of resources but also increases the cost of products. Using a 74HC595 chip to drive LED has various disadvantages. High speed, low power consumption, unlimited number of  LED s. It can control both the common cathode LED display and the common anode LED display. The circuit designed with 74HC595  is not only simple but also low in power consumption and strong in driving ability. It is a low-cost and flexible design scheme.2.2 74HC595The 74HC595 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. Both the shift and storage register have separate clocks. The device features a serial input (DS) and a serial output (Q7S) to enable cascading and an asynchronous reset MR input. A LOW on MR will reset the shift register. Data is shifted on the LOW-to-HIGH transitions of the SHCP input. The data in the shift register is transferred to the storage register on a LOW-to-HIGH transition of the STCP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register. Data in the storage register appears at the output whenever the output enable input (OE) is LOW. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the registers. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.Figure 1. 74HC595 Functional DiagramFigure 2. 74HC595 Logic SymbolIII. Circuit Design3.1 Hardware CircuitFigure 3 is a display panel circuit designed with AT89C2051 and  74HC595 interface.Figure 3. Circuit of Display PanelThe P115, P116, and P117 of the P1 port are used to control the display of the LED.  and they are connected to the SLCK, SCLK, and SDA pins respectively. Three digital tubes are used to display the voltage value. On the circuit board, LED3 is on the far left and LED1 is on the far right. When sending data, first send the display code of LED3, and finally, send the display code of LED1. The brightness of the  LED is controlled by the resistance of PR1 to PR3.2.2 Display DriverUse DISP1, DISP2, and DISP3 to store display data. After the CPU initialization is complete, call the LRDISP subroutine to clear the register of 74HC595. There is no need to call the clear subroutine before calling the display subroutine DISPLAY. Now write the two subroutines as follows.①CLRDISP:MOVR2，#24CLRBIT：CLRSCLKCLRCMOVSDA，CSETBSCLKDJNZR2，CLRBITRET②Display:CLRSLCKMOVR3，#3MOVR0，#DISP3DISP1：MOVA，@R0MOVR2，#8DISP2：CLRSCLKRLCAMOVSDA，CSETBSCLKDJNZR2，DISP2DECR0DJNZR3，DISP1SETBSLCKRETIV. ConclusionIt can be seen from the above examples that there are no complicated technical problems in the design of hardware and software when 74HC595 is used to design an LED driver circuit. In addition, 74HC595 can be used not only to drive LED displays but also to drive light-emitting diodes. Each 74HC595 can drive 8 LEDs simultaneously. This solution is ideal when the volume requirements of the product are not high and want to reduce the cost. FAQWhere can the 74HC595 be used to drive LED operation?MCU interfaceWhat does the 74HC595 feature to enable cascading and an asynchronous reset MR input?A serial input (DS) and a serial output (Q7S)What is 74HC595?74HC595 is a shift register which works on Serial IN Parallel OUT protocol.

However, unlike standard diodes, the Schottky diode is known for its low forward voltage and fast switching ability. This makes them an ideal choice for radio frequency applications and any device with low voltage requirements. What is the principle of Schottky diode?In a Schottky diode, a semiconductor–metal junction is formed between a semiconductor and a metal, thus creating a Schottky barrier. The N-type semiconductor acts as the cathode and the metal side acts as the anode of the diode. This Schottky barrier results in both a low forward voltage drop and very fast switching. Is Schottky diode a zener diode?Schottky diodes and Zener diodes are two different types of diodes. The main difference between Schottky and Zener diode is that a Schottky diode is made of a metal-semiconductor junction whereas a Zener diode is made of a p-n junction of two highly-doped semiconductors.
