Overview of ULN2003APW

The ULN2003APW is a high voltage, high current Darlington transistor array. It consists of seven NPN Darlington pairs that are capable of handling up to 500mA of continuous current per channel. This makes it a versatile and efficient choice for driving a wide range of inductive loads such as relays, solenoids, and stepper motors.The ULN2003APW also features clamp diodes for each channel, providing protection against back EMF generated by the inductive loads. This helps to prolong the lifespan of the array and prevent damage to the connected components.In terms of voltage handling, the ULN2003APW can tolerate input voltages of up to 50V, making it suitable for use in a variety of high voltage applications. It is also designed to be compatible with TTL and CMOS inputs, offering flexibility in its interfacing capabilities.
