ULN2803 Darlington Transistor Arrays IC DIP 18 Package

ULN2803 Darlington Transistor Arrays IC DIP 18 Package.The ULN2803 is a high-current Darlington transistor array IC designed to interface low-level logic circuits with higher-power loads. It contains eight NPN Darlington transistor pairs with open-collector outputs, allowing it to drive relays, solenoids, motors, lamps, and LED displays directly from TTL or CMOS logic signals.Each channel includes a built-in flyback (clamp) diode for safe switching of inductive loads, reducing the need for external protection components. Packaged in a DIP-18 through-hole package, the ULN2803 is easy to use in prototyping, educational, and industrial control applications.Click here to view related productsFeaturesEight NPN Darlington transistor channelsHigh current output capability (up to 500 mA per channel)Output voltage rating up to 50 VBuilt-in clamp diodes for inductive load protectionLogic-level compatible inputs (TTL/CMOS)Open-collector outputsCommon emitter configurationLow input current requirementDIP-18 package for easy PCB mounting and prototypingApplicationsRelay and solenoid driversDC motor and stepper motor controlLED and lamp drivingDisplay segment and matrix driversIndustrial automation and control systemsMicrocontroller and logic IC interfacingRobotics and embedded systemsuln2803-ic-datasheet*Product image for illustration purposes only, actual product may vary.
