RHR801K1
Overview
The RHR801K1 is a radiation-hardened, high-speed single comparator designed for extreme environments. It features a rail-to-rail input, an open-collector output for flexible logic interfacing, and is housed in a ceramic 8-CFlatPack package. With a 12ns propagation delay and immunity to heavy ion-induced effects, it is engineered for critical aerospace and defense systems.
Why Choose This Part
The RHR801K1 provides exceptional reliability in harsh environments with 100 krad high-dose rate tolerance and SEL immunity up to 120 MeV.cm2/mg. Its fast 12ns propagation delay and 4mV hysteresis ensure precise switching performance, while the open-collector output simplifies level shifting between different logic families.
Applications
Key Specifications
Getting Started
Designers should follow STMicroelectronics Rad-Hard design guidelines, ensuring proper decoupling of the 3V to 6V supply. Since this is an open-collector device, an external pull-up resistor is required on the output pin to establish the high logic level. Evaluation of flight-grade prototypes is typically done using the RHR801K1 engineering model before transitioning to QML-V certified flight hardware.
