description

The ULQ2003A-Q1 and ULQ2004A-Q1 are high-voltage, high-current Darlington transistor arrays. Each

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.

The ULQ2003A-Q1 has a 2.7-k

Ω series base resistor for each Darlington pair, for operation directly with TTL

or 5-V CMOS devices. The ULQ2004A-Q1 has a 10.5-k

Ω series base resistor to allow operation directly from

CMOS devices that use supply voltages of 6 V to 15 V. The required input current of the ULQ2004A-Q1 is below

that of the ULQ2003A-Q1.
