3 Description
The ULQ200x A-Q1 devices are high-voltage highcurrent Darlington transistor arrays. Each consists of seven npn Darlington pairs that feature high-voltage outputs with mon-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 m A. The Darlington pairs can be paralleled for higher current capability.
The ULQ2003A-Q1 has a 2.7-kΩ series base resistor for each Darlington pair, for operation directly with TTL or 5-V CMOS devices. The ULQ2004A-Q1 has a 10.5-kΩ series base...
