ULN 2803/2804
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 eight NPN Darlington connected transistors in this family of arrays
OCTAL PERIPHERAL
are ideally suited for interfacing between low logic level digital circuitry (such DRIVER ARRAYS
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 SEMICONDUCTOR
feature open–collector outputs and free wheeling clamp diodes for transient TECHNICAL DATA
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.
