The ULQ2003A is a monolithic high-voltage,
E⁸
9 _COM
high-current Darlington transistor array. The
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 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. The ULQ2003A has a 2.7-kΩ series base resistor for each
Darlington pair for operation directly with TTL or 5-V CMOS devices.
The ULQ2003A is offered in standard 16-pin dual in-line (N) and surface-mount (D) packaging. The device is
characterized for operation over the junction temperature range of –40°C to 105°C.
