ULN2004A DIP16 MCU Microcontroller Integrated Circuits ULN2004A

ULN2004A is a high-voltage, high-current darlington transistor array. The device contains seven darlington transistors with common emitters and clamp diodes for inductive loads. It is commonly used as a driver for high-power loads such as relays, motors, and lamps, in applications ranging from home appliances to industrial control systems. The ULN2004A is designed to operate with TTL and CMOS logic-level inputs and has an output current rating of 500mA per channel. The device also features input protection diodes, which guard against voltage spikes, preventing damage to the chip. Additionally, ULN2004A can be used in various industrial, automotive, and military applications for its characteristics such as common-cathode clamp diodes and its 50V collector-emitter breakdown voltage.
