ULN2804APG Darlington Transistor Array
The eight NPN Darlington connected transistors in this family of arrays are ideally suited for interfacing between low logic level digital circuitry (such as TTL, CMOS, or PMOS/NMOS) and the higher current/voltage requirements of lamps, relays, printer hammers, or other similar loads for a broad range of computer, industrial, and consumer applications. All devices feature open–collector outputs and free-wheeling clamp diodes for transient suppression.
