ULN2004 IC IK SEMI DIP-16 ULN2004

Product Overview

The ULN2004 is a high-voltage, high-current Darlington transistor array designed for switching inductive loads. It consists of seven NPN Darlington pairs, each capable of sinking up to 500 mA. Each channel includes an integral flyback/clamp diode, which protects the device and the controlling logic circuit from voltage spikes when driving inductive loads like relays, solenoids, or stepper motors. The ULN2004 is specifically optimized for direct interfacing with 6V to 15V PMOS and CMOS logic families due to its internal input base resistor.
