ULN2004D1 - Brand New STMicroelectronics Transistors (BJT) - Arrays
-
Description
The ULN2004D1 is a high voltage, high current darlington array which contains seven open collector darlington pairs with common emitters. It is designed for applications that require driving high current loads such as relays, solenoids, stepper motors, and lamps. The ULN2004D1 has a maximum output current of 500 mA per driver and can withstand peak currents of up to 600 mA. It also features integrated suppression diodes for driving inductive loads and the inputs are pinned opposite the outputs to simplify board layout.
