Features
Description
• Four Independent EXCLUSIVE NOR Gates
• Buffered Inputs and Outputs
• Logical Comparators
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.

• Parity Generators and Checkers
• Adders/Subtracters
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.
