Features, Applications

Replaces SN74AS305 Maximum Output Skew 1 ns Maximum Pulse Skew 1 ns TTL-Compatible Inputs and Outputs Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise Package Options Include Plastic Small-Outline (D) Package and Standard Plastic (N) 300-mil DIPs


The CDC305 contains eight flip-flops designed to have low skew between outputs. The eight outputs (four in-phase with CLK and four out-of-phase) toggle on successive CLK pulses. Preset (PRE) and clear (CLR) inputs are provided to set the Q and Q outputs high or low independent of the clock (CLK) input. The CDC305 has output and pulse-skew parameters tsk(o) and tsk(p) to ensure performance as a clock driver when a divide-by-two function is required. The CDC305 is characterized for operation from to 70°C.

H Q0 This configuration does not persist when PRE or CLR returns to its inactive (high) level.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.

CLR PRE CLK R C1 This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.

absolute maximum ratings over operating free-air temperature range (unless otherwise noted)

Supply voltage, VCC. 7 V Input voltage, VI. 7 V Maximum power dissipation = 55°C (in still air) (see Note 1): D package. W N package. 1.2 W Storage temperature range, Tstg. to 150°C

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 300 mils, except for the N package, which has a trace length of zero. For more information, refer to the Package Thermal Considerations application note in the 1994 ABT Advanced BiCMOS Technology Data Book, literature number SCBD002B.

electrical characteristics over recommended operating free-air temperature range (unless otherwise noted)

ICC VCC 5.5 V, See Note 70 mA All typical values are at VCC = 25°C. The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS. NOTE 2: ICC is measured with CLK and PRE grounded, then with CLK and CLR grounded.
