The ULN2068B is a high–voltage, high–current quad Darlington switch array designed for high-current loads, both resistive and reactive, up to 300 W. It is intended for interfacing between low-level (TTL, DTL, LS and 5.0 V CMOS) logic families and peripheral loads such as relays, solenoids, dc and stepping motors, multiplexer LED and incandescent displays, heaters, or other high voltage, high current loads.
