1. General description

The HEF4077B is a quad 2-input EXCLUSIVE-NOR gate. Inputs include clamp diodes. This

enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 3) and is suitable for use in automotive applications.
