What are the key features of HCC4077BDG?
- Radiation-hardened CMOS construction for space and military electronics
- Quad 2-input XNOR gate (4 independent functions per package) from the 4000B logic family
- Ceramic, glass-sealed DIP-14 package providing superior hermeticity and long-term reliability
- High-voltage wide supply range typical of CMOS 4000B series (3 V to 18 V)
- Temperature-stable operation for harsh environment deployment
- 5-year estimated product life in high-reliability supply chains
What is HCC4077BDG used for?
HCC4077BDG is used in radiation-tolerant digital logic circuits for aerospace, satellite, and defense electronics where standard plastic-package CMOS ICs would be susceptible to single-event upsets or total ionizing dose degradation. The quad XNOR function is used for parity checking, comparator logic, and phase detection circuits in flight computers and military signal processing boards. Its ceramic DIP-14 package also suits high-reliability industrial control systems with stringent lifetime and hermetic sealing requirements.

Frequently Asked Questions
What logic function does each gate in HCC4077BDG perform and how many independent gates are available per package?
Each gate in HCC4077BDG implements a 2-input XNOR logic function, and the package contains 4 independent XNOR gates in a single DIP-14 ceramic package. XNOR outputs logic HIGH when both inputs are equal, making it useful for digital comparators, parity generators, and phase detectors.
Why is HCC4077BDG packaged in a ceramic glass-sealed DIP rather than a standard plastic package?
HCC4077BDG uses a ceramic, glass-sealed DIP-14 package (JESD-30 R-GDIP-T14) to provide hermetic sealing, which prevents moisture ingress and outgassing. This package type is mandatory in space, military, and high-reliability defense applications where a plastic package would fail under radiation, extreme thermal cycling, or long storage life requirements.
How does HCC4077BDG's radiation hardening affect its suitability for low-Earth orbit satellite designs?
Radiation hardening in HCC4077BDG makes it resistant to total ionizing dose (TID) and single-event effects common in low-Earth orbit, where unshielded CMOS logic would accumulate threshold voltage shifts and latch-up risk. Rad-hard qualification ensures the XNOR logic outputs remain correct over the satellite's multi-year mission life, which standard 4000B plastic devices cannot guarantee.
What supply voltage range does the 4000B CMOS family support for HCC4077BDG in mixed-voltage system designs?
The CMOS 4000B family supports a wide supply voltage range typically from 3 V to 18 V, and HCC4077BDG inherits this wide-voltage compatibility. This allows the device to interface with both 5 V TTL-compatible systems and higher 12 V or 15 V industrial logic buses without additional level translation, simplifying mixed-voltage high-reliability circuit designs.
