HIGH VOLTAGE, HIGH CURRENT

DARLINGTON TRANSISTOR ARRAYS

Description

The ULN2002A, ULN2003A and ULN2004A are high voltage, high
current Darlington arrays each containing seven open collector
common 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.

Device options are designed to be compatible with common logic
families:

ULN2002A

(14-25V

PMOS)

ULN2003A (5V TTL, CMOS)

ULN2004A (6-15V CMOS, PMOS)

These devices are capable of driving a wide range of loads including
solenoids, relays, DC motors; LED displays, filament lamps, thermal
print-heads and high power buffers.

The ULN2002A, 2003A and 2004A are supplied in a small outline
16 pin package (SO-16).
