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 ULN2803 is designed to be compatible with standard TTL families.
The ULN2803 are available in SIP18,DIP18,QFN20 and SSOP24 packages.
