UNISONIC TECHNOLOGIES CO., LTD ULN2003R Preliminary LINEAR INTEGRATED CIRCUIT HIGH VOLTAGE HIGH CURRENT DARLINGTON TRANSISTOR ARRAY  DESCRIPTION The UTC ULN2003R is 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 500mA. All units feature integral clamp diodes for switching inductive loads. Applications include relay, hammer, lamp and display (LED) drivers. The UTC ULN2003R has a 2.7kΩ series base resistor for each darlington pair for operation directly with TTL or 5V CMOS devices.
