Hi-Rel RS-485/RS-422 Serial Interface

Hi-Rel RS-422 transceivers provide robust radiation-tolerant 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-422 standards, they enable dependable networking for spacecraft, satellites, and mission-critical systems. Hi-Rel RS-485 transceivers deliver reliable communication built to perform in the harshest environments.

Renesas offers products across many screening flows: QML-V, QML-V-equivalent, QML-P, QML-P-equivalent, and RT Plastic. Refer to product datasheets to determine which flows are applicable.
