Part Number ULN2803A
Description OCTAL PERIPHERAL DRIVER ARRAYS
Feature Octal High Voltage, High Current Darling ton Transistor Arrays The eight NPN Dar lington connected transistors in this f amily of arrays are ideally suited for interfacing between low logic level dig ital circuitry (such as TTL, CMOS or PM OS/NMOS) and the higher current/voltage requirements of lamps, relays, printer hammers or other similar loads for a b road range of computer, industrial, and consumer applications.
All devices fea ture open–collector outputs and free wheeling clamp diodes for transient sup pression.
The ULN2803 is designed to be compatible with standard TTL families while the ULN280 .
