Hi-Rel RS-485 & RS-422 transceivers provide radiation-tolerant, robust communication for space and high-reliability applications. Designed to ensure long-distance, noise-resistant data transmission, these transceivers operate reliably in harsh radiation environments. With fault protection, low-power operation, and compliance with RS-485/RS-422 standards, they enable dependable networking for spacecraft, satellites, and mission-critical systems.
Renesas offers products across many screening flows: QML-V, QML-V Equivalent, QML-P, QML-P Equivalent, and RT Plastic. Refer to the product datasheet to determine which flows are applicable.
Fail Safe Operation
Our products are equipped with fail safe circuitry to enable safe operation, even when the inputs are open.
Cold Sparing Capability
Our RS-485/RS-422 products are cold sparing capable on the output pins, presenting high impedance to the line with the power off and maintaining signal integrity in multi-driver/receiver applications.
Designed for Space
Engineered from the ground up for space applications, these products mitigate SEE and TID effects, ensuring mission-critical reliability without additional design overhead.
