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 VDD power supply range of 3 V to 15 V

referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, 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
