Add To BomULN2004A General Description
The ULN2004A is a high voltage, high current Darlington transistor array integrated circuit. It consists of seven NPN Darlington pairs that can handle continuous output currents up to 500 mA per channel and peak currents up to 600 mA. The ULN2004A is commonly used as a driver for loads such as relays, motors, and solenoids in various electronic applications.Each Darlington pair in the ULN2004A has a diode for protection against inductive kickback and a base resistor to limit the base current. This helps to simplify the interface between low-level logic signals and higher power loads. The ULN2004A is capable of driving both inductive and resistive loads, making it versatile for a wide range of applications.The ULN2004A is available in a 16-pin DIP package, making it easy to integrate into circuits. It is ideal for use in applications that require high current and high voltage drive capability, such as in automotive, industrial, and robotics applications
