What are the key features of CD4077BEE4?
- 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
What is CD4077BEE4 used for?
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.
