relay and indicator light driver DOWO ULN2003 DW Darlington transistor array with TTL CMOS compatibility

ULN2003 Darlington Transistor Array

The ULN2003 is a monolithic high-voltage, high-current Darlington transistor array. It internally contains seven independent Darlington drive channels, each with a freewheeling diode for inductive loads like relays and stepper motors. Each Darlington pair can output up to 500mA, with parallel channels offering higher current capability. This array is widely used for relay driving, lighting, LED displays, stepper motors, and as logic buffers. Each channel includes a 2.7K base resistor, allowing direct connection to TTL/CMOS circuits at 5V, simplifying signal processing.

Key Features

500mA rated collector current (per channel)
High operating voltage (40V)
Input compatible with TTL/CMOS logic signals
Wide application in relay driving
Available in SOP16 and DIP16 packages

Main Application Fields

Relay Drivers
Indicator Light Drivers
Display Drivers (LED)
