Keystone Electronics 2982TR

drivers, print hammers, and LEDs.

All devices may be used with 5 V logic systems — TTL, Schottky TTL, DTL, and 5 V CMOS. The UDN2981A, UDN2982A, and A2982SLW are electrically interchangeable, will withstand a maximum output off voltage of 50 V, and operate to a minimum of 5 V. All devices in this series integrate input current limiting resistors and output transient suppression diodes, and are activated by an active high input.
The suffix ‘A’ (all devices) indicates an 18-lead plastic dual in-line package with copper lead frame for optimum power dissipation. Under normal operating conditions, these devices will sustain 120 mA continuously for each of the eight outputs at an ambient temperature of +50°C and a supply of 15 V.
The suffix ‘LW’ (UDN2982LW only) indicates an 18-lead surface mountable wide-body SOIC package; the A2982SLW is provided in a 20-lead wide-body SOIC package with improved thermal characteristics.
The UDN2982A, UDN2982LW, and A2982SLW drivers are also available for operation over an extended temperature range to -40°C. To order, change the prefix ‘UDN’ to ‘UDQ’ or the suffix ‘SLW’ to ‘ELW’.
These packages are available in Pb (lead) free variants (suffix ‘-T’), with 100% matte-tin leadframe plating.
