Overview
The ULQ2003D1, produced by STMicroelectronics, is a high voltage, high current Darlington array. This device contains seven open collector Darlington pairs with common emitters, making it versatile for driving a wide range of loads. It is available in both 16-pin plastic DIP packages and small outline packages (SO16), with the SO16 version also available as an Automotive Grade product. The ULQ2003D1 is designed to interface with all common logic families, including TTL, CMOS, PMOS, and DTL, and features integrated suppression diodes for inductive load driving.
