7-DIGIT DARLINGTON CURRENT DRIVER

FEATURES

- 7 Darlington Arrays per Package

- 500 mA Rated Collector Current (Single Output)

- Output voltage 50V

- Output Clamp Diodes

- Input Compatible with Various Types of Logic

- Relay-Driver Applications

- Input pins placed opposite to output pins to simplify layout

DESCRIPTION

The ULN2003A and ULN2004A are monolithic high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 mA. The Darlington pairs may be paralleled for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
