Datasheet
1. General description
The HEF4077B is a quad 2-input EXCLUSIVE-NOR gate. The outputs are fully buffered
for the highest noise immunity and pattern insensitivity to output impedance.
The HEF4077B operates over a recommended V
DD
power supply range of 3 V to 15 V
referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or
another input.
2. Features and benefits
Fully static operation
5 V, 10 V, and 15 V parametric ratings
Standardized symmetrical output characteristics
Specified from 40 C to +85 C
Complies with JEDEC standard JESD 13-B
