ULN2003AN - 7-Darlington Transistor Arrays IC

The ULN2003 is a monolithic IC consists of seven NPN darlington transistor pairs with high capability. It is commonly used for applications such as relay drivers, motor, display drivers, led lamp drivers, logic buffers, line drivers, hammer drivers and other high voltage current applications. It consists of common cathode clamp diodes for each NPN darlington pair which makes this driver IC useful for switching inductive loads.

ULN2003 is widely used in relay driving and stepper motor driving applications.

ULN2003 Features
