Description
The ’HC7266 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.
