Relay-Driver Applications

The

ULN2003AI

is

a

high-voltage,

high-current

Darlington transistor array. This device 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 can 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.

CMOS devices.
