The UTC ULN2001 is high-voltage, high-current darlington transistor arrays. Each consists of three 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 500mA. All units feature integral clamp diodes for switching inductive loads. Applications include relay, hammer, lamp and display (LED) drivers. The UTC ULN2001 has a 2.7kΩ series base resistor for each darlington pair for operation directly with TTL or 5V CMOS devices.
