Key Features
- Quad 2-input XNOR gate with 4 independent functions in a single 14-pin PDIP, enabling compact equivalence detection and parity checking logic
- 4000-series CMOS family supports 3 V to 18 V supply range, ensuring compatibility with TTL, CMOS, and mixed-voltage digital systems
- 50 pF rated load capacitance allows direct fan-out to standard CMOS inputs without external buffering in most digital logic designs
Applications
The CD4077BEE4 is used in digital comparator circuits, parity generation, and error detection logic where 4 independent XNOR decisions are needed in a single package. It suits data integrity checking in communication interfaces, bit comparators in programmable logic controllers, and signal phase detection in industrial sensing systems. The 14-pin PDIP package makes it easy to prototype on breadboards and replace in through-hole production assemblies.

Frequently Asked Questions
How many independent XNOR gates does the CD4077BEE4 contain and how many inputs does each gate have?
The CD4077BEE4 contains 4 independent XNOR gates, each with 2 inputs, all within a single 14-pin PDIP package. This quad configuration allows simultaneous multi-bit equivalence comparison in data comparators, reducing IC count compared to using 4 discrete 2-input gates from separate packages.
What supply voltage range does the CD4077BEE4 support, and how does this affect system compatibility?
As a 4000-series CMOS device, the CD4077BEE4 operates from 3 V to 18 V, allowing it to interface with 5 V TTL logic, 3.3 V CMOS systems, and 12 V industrial control buses. This wide range means a single part number satisfies design requirements across multiple product generations without redesigning the logic board.
What practical applications benefit most from using XNOR gates like the CD4077BEE4?
XNOR gates output a logic high only when both inputs are equal, making the CD4077BEE4 ideal for bit-level equality comparators, parity checkers in serial communication lines, and phase coincidence detectors in phase-locked loop circuits. Each of the 4 gates can check 1 bit pair, enabling a 4-bit word comparator using a single 14-pin IC.
