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. | Order this document by ULN2803 D MOTOROLA Octal High Voltage High Current Darlington Transistor Arrays 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. The ULN2803 is designed to be compatible with standard TTL families while the ULN2804 is optimized for 6 to 15 volt high level CMOS or PMOS.
