ILN2003A

HIGH-VOLTAGE HIGH-CURRENT

DARLINGTON TRANSISTOR ARRAYS

The ILN2003A are monolithic high-voltage, high-current

Darlington transistor arrays. Each consists of seven n-p-n

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.
