Frequently Asked Questions
What logic function does the CD4077BF perform?
The CD4077BF contains four independent 2-input XNOR (exclusive-NOR) gates, each producing a HIGH output when both inputs are at the same logic level. This equivalence function is fundamental in applications such as parity checkers, digital comparators, and phase-locked loop phase detectors.
What package is the CD4077BF available in?
The CD4077BF is housed in a 14-pin Ceramic Dual-In-Line Package (CDIP), which provides excellent hermetic sealing and mechanical durability compared to plastic DIP variants. The ceramic package is preferred in high-reliability, military-grade, and extended-temperature applications.
What is the load capacitance rating for the CD4077BF?
The CD4077BF is rated for a load capacitance of 50pF per output, which is typical for standard PCB trace connections at moderate signal speeds. Exceeding this capacitance may reduce switching speed, so designers should keep trace lengths short or add buffers for heavier loads.
What supply voltage does the CD4077BF support?
As a member of the CMOS 4000 family, the CD4077BF supports a wide supply voltage range, typically from 3V to 18V. This broad range allows it to interface with TTL, CMOS, and other logic families operating at different supply voltages in mixed-voltage systems.
Is the CD4077BF suitable for long-term or legacy design support?
Yes, the CD4077BF has a projected YTEOL (Years To End Of Life) of 15 years, indicating long-term availability from Texas Instruments. This makes it a reliable choice for legacy system maintenance, military spares provisioning, and industrial designs requiring multi-decade component availability.
