What are the key features of RHFAC08K04V?
- Radiation-hardened 5 V CMOS AND gate designed for space and defense applications requiring reliable logic operation in ionizing radiation environments
- Quad 2-input AND configuration with 4 independent gates in a single 14-pin ceramic flatpack, minimizing IC count in radiation-tolerant designs
- Ceramic metal-sealed cofired flatpack package provides hermetic protection against moisture and mechanical shock in harsh aerospace environments
What is RHFAC08K04V used for?
RHFAC08K04V is designed for space-grade digital logic circuits where radiation tolerance is a primary requirement, such as satellite attitude control computers, launch vehicle avionics, and nuclear instrumentation systems. Its 5 V CMOS AC-series logic ensures high-speed gate switching compatible with radiation-hardened FPGAs and processors used in space missions. The hermetic 14-pin ceramic flatpack enables reliable long-duration operation in vacuum and high-radiation orbit environments where commercial plastic packages are not acceptable.

Frequently Asked Questions
What logic function and gate count does RHFAC08K04V provide in a single package?
RHFAC08K04V contains 4 independent 2-input AND gates in a 14-pin ceramic flatpack, each gate accepting 2 logic inputs. This quad configuration reduces component count in radiation-hardened digital designs that need multiple AND functions in a single 5 V CMOS device.
Why is the ceramic flatpack package chosen for RHFAC08K04V in space applications?
The 14-pin ceramic metal-sealed cofired flatpack provides hermetic sealing that prevents moisture ingress and outgassing in vacuum environments, and survives mechanical shock and vibration during launch. Commercial plastic packages absorb moisture and degrade in the high-radiation flux of low-Earth orbit over multi-year mission lifetimes.
What supply voltage does RHFAC08K04V operate from, and how does this compare with 3.3 V CMOS logic?
RHFAC08K04V operates from a 5 V CMOS supply rail, providing higher noise margins and output drive current than 3.3 V CMOS logic, which is important in radiation environments where single-event transients can corrupt logic states. The 5 V rail is the standard for many radiation-hardened logic families qualified to MIL-STD-883 or equivalent.
In which high-reliability system categories is RHFAC08K04V typically used?
RHFAC08K04V is used in satellite onboard computers, nuclear power plant instrumentation, and high-altitude avionics where the cumulative radiation dose can exceed 100 krad(Si). Its radiation-hardened 5 V AC-series CMOS logic maintains defined switching thresholds and output drive capability after extended exposure to total ionizing dose and single-event effects.
