Description

The

Harris

CD74HC7266

contains

four

independent

Exclusive NOR gates in one package. They provide the

system designer with a means for implementation of the

EXCLUSIVE NOR function.

This device is functionally the same as the TTL226. They

differ in that the HC7266 has active high and low outputs

whereas the 226 has open collector outputs.
