DESCRIPTIONThe HCF4077B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4077B contains four independent
exclusive NOR gates. This device provides the
system designer with a means for direct
implementation of the exclusive-NOR. For
applications as logical comparators, adders/
subtractors, parity generator and checkers.
