ULN2002A/ ULN2003A/ ULN2004A ULN2004A HIGH VOLTAGE, HIGH CURRENT DARLINGTON TRANSISTOR ARRAYS Description Pin Assignments The ULN2002A, ULN2003A and ULN2004A are high voltage, high current Darlington arrays each containing seven open collector (Top View) common emitter pairs. Each pair is rated at 500mA. Suppression diodes are included for inductive load driving, the inputs and outputs 1B 1 16 1C are pinned in opposition to simplify board layout. 2B 2 15 2C Device options are designed to be compatible with common logic 3B 3 14 3C families: 4B 4 13 4C ULN2002A (14-25V PMOS) 5B 5 12 5C ULN2003A (5V TTL, CMOS) 6B 6 11 6C ULN2004A (6-15V CMOS, PMOS) 7B 7 10 7C These devices are capable of driving a wide range of loads including E 8 9 COM solenoids, relays, DC motors, LED displays, filament lamps, thermal print-heads and high-power buffers. SO-16 The ULN2002A, ULN2003A and ULN2004A are available in both a small outline 16-pin package (SO-16) and PDIP-16 package.
