General Description
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 ULN2803F is designed to be compatible with standard TTL families while the ULN2804 is optimized for 6
to 15 volt high level CMOS or PMOS.
