ULN2804 Octal Peripheral Driver Arrays – Datasheet

The ULN2804 Octal Peripheral Driver 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 freewheeling clamp diodes for transient suppression. le the ULN2804 is optimized for 6 to 15 volt high-level CMOS or PMOS.
