ULN2803A datasheet

Description :

The ULN2803A device is a high-voltage, high-current 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.Types of Logic pairs may be connected in parallel for higher current capability.


1. 500-mA-Rated Collector Current (Single Output)

2. High-Voltage Outputs: 50 V

3. Output Clamp Diodes


4. Inputs Compatible With Various Types of Logic
