description

The ULQ2003A is a monolithic high-voltage,

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-k

Ω 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.
