ULN2002A/ULN2003A/ULN2004A
HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON TRANSISTOR ARRAYS
Description
The ULN2002A, ULN2003A, and ULN2004A are high-voltage, highcurrent Darlington arrays each containing seven open collector mon emitter pairs. Each pair is rated at 500mA. Suppression diodes are included for inductive load driving. The inputs and outputs are pinned in opposition to simplify board layout.
Pin Assignments
Device options are designed to be patible with mon logic families:
- ULN2002A (14V to 25V PMOS)
- ULN2003A (5V TTL, CMOS)
- ULN2004A (6V to15V CMOS, PMOS)
These devices are capable of driving a wide range of loads including solenoids, relays, DC motors, LED displays,...
