RHFXH162244K1
Overview
The RHFXH162244K1 is a radiation-hardened 16-bit non-inverting buffer/line driver with 3-state outputs, specifically designed for high-reliability aerospace and defense applications. It operates over a 1.8V to 3.6V supply range and features built-in 26 Ohm series resistors at the outputs to reduce line noise without external components. This QML-V qualified device is engineered to withstand extreme radiation environments, including total ionizing dose and single-event effects.
Why Choose This Part
This device offers exceptional radiation performance with a Total Ionizing Dose (TID) rating of 300 krad(Si) and immunity to SEL, SEU, and SET up to 110 MeV.cm2/mg. The integrated 26 Ohm series resistance simplifies PCB layout by providing built-in termination, while the cold-spare function and bus-hold features enhance system-level reliability in redundant architectures.
Applications
Key Specifications
Getting Started
Engineers should consult the SMD 5962F05210 specification and the STMicroelectronics Rad-Hard databook for detailed timing and radiation performance curves. Prototyping is typically performed using ceramic 48-pin flat pack sockets or specialized evaluation boards designed for high-speed signal integrity and thermal management. Integration requires strict adherence to MIL-STD-883 assembly and screening procedures to maintain QML-V compliance.
