ULQ2003AN

TEXAS INSTRUMENTS  ULQ2003AN  双极晶体管阵列, NPN, 50 V, 500 mA, 1000 hFE, DIP

description/ordering information

The ULN2001A, ULN2002A, ULN2003A, ULN2004A, ULQ2003A, and ULQ2004A 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. For 100-V otherwise interchangeable versions of the ULN2003A and ULN2004A, see the SN75468 and SN75469, respectively.
