HEF4077B
Quad 2-input EXCLUSIVE-NOR gate
Rev. 6 — 14 March 2017 Product data sheet
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
