Overview

The RHFACT14K1 is a radiation-hardened hex inverter with Schmitt trigger inputs, specifically designed for high-reliability aerospace and defense applications. Operating between 4.5V and 5.5V, this 6-channel device provides robust signal conditioning and noise immunity in extreme environments. It is housed in a 14-pin ceramic flatpack to ensure long-term integrity under vacuum and high-radiation conditions.

Why Choose This Part

This device features Schmitt trigger inputs that provide excellent noise margins and the ability to transform slow-moving or noisy input signals into clean, fast digital outputs. Its radiation-hardened design and hermetic 14-CFlatPack packaging allow it to operate reliably over a wide temperature range of -55C to 125C.

Applications

Satellite Control Systems
Used for signal squaring and logic inversion in satellite bus telemetry and command modules.
Radiation-Hardened Logic Gates
Acts as a high-noise-immunity interface for digital signal paths in orbital electronics.
Launch Vehicle Avionics
Provides reliable signal conditioning for sensors and actuators in harsh vibration and radiation environments.

Getting Started

Prototyping with this component typically requires specialized handling and PCB footprints for ceramic flatpacks. Engineers should consult the STMicroelectronics Rad-Hard Databook for specific Total Ionizing Dose (TID) and Single Event Effects (SEE) characterization data to ensure compliance with mission requirements. Verification is often performed using high-reliability test fixtures rather than standard breadboards.
