uln2003 datasheet

HIGH VOLTAGE AND HIGH CURRENT


DARLINGTON TRANSISTOR ARRAY

DESCRIPTION

The ULN2003 is a monolithic high voltage and high current

Darlington transistor arrays. It consists of seven NPN darlington

pairs that features high-voltage outputs with common-cathode

clamp diode for switching inductive loads. The collector-current

rating of a single darlington pair is 500mA. The darlington pairs

may be parrlleled for higher current capability. Applications include

relay drivers,hammer drivers, lampdrivers,display drivers(LED gas

discharge),line drivers, and logic buffers.

The ULN2003 has a 2.7kΩ series base resistor for each

darlington pair for operation directly with TTL or 5V CMOS

devices.

FEATURES

* 500mA rated collector current(Single output)

* High-voltage outputs: 50V

* Inputs compatibale with various types of logic.

* Relay driver application
