ULN2803 Darlington Transistor Driver Array IC

Description

The ULN2803A device is a 50 V, 500 mA Darlington transistor array. The device consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability.

Features:
500-mA-Rated Collector Current (Single Output)
High-Voltage Outputs: 50 V
Output Clamp Diodes
Inputs Compatible With Various Types of Logic
