ULN 2803 AN (8 Chain CMOS/TTL INP Driver 18pin)

Description: The ULN2803A is an integrated circuit that has eight Darlington transistor arrays. It is commonly used to drive high-current loads using low-logic level digital circuits like TTL or CMOS. High Voltage, High Current Darlington Transistor Arrays: Each of the ULN2803A's eight Darlington couples can drive up to 500mA at 50V. Input Compatibility: Designed for direct interfacing with standard logic families like as TTL and CMOS. Integral Suppression Diodes: These include flyback diodes, which protect transistors from inductive loads.
