Product Summary

The ULN2803 is a octal high voltage, high current darlington transistor array. The ULN2803 is ideally suited for interfacing between low logic level digital circuitry (such as TTL, CMOS or PMOS/NMOS) and the higher current/voltage requirements of lamps, relays, printer hammers or other similar loads for a broad range of computer, industrial, and consumer applications.

Parametrics

ULN2803 absolute maximum ratings: (1)Output Voltage:50 V; (2)Input Voltage (Except ULN2801):30 V; (3)Collector Current – Continuous :500 mA; (4)Base Current – Continuous:25 mA; (5)Operating Ambient Temperature Range :0℃ to +70℃; (6)Storage Temperature Range: –55℃ to +150℃; (7)Junction Temperature: 125℃.

Features

ULN2803 features: (1)Output current (single output) 500mA MAX. ; (2)High sustaining voltage output 50V MIN. ; (3)Output clamp diodes ; (4)Inputs compatible with various types of logic.
