Analog Devices’ Rugged RS485 Transceiver Delivers in Extreme Temperature & High Noise Environments

Jun 20 2018 - Norwood, MA

  • LTC2879XAnalog Devices, Inc. today introduced the LTC2879X extreme temperature 175°C ±60V fault tolerant RS485/RS422 transceiver. The device is engineered to operate in demanding temperature ranges and is 100% tested to specifications at 175°C. Features such as enhanced overvoltage fault protection and extreme electrical overstress (EOS) protection ensure reliable data communications against the most common threats in electrically noisy environments. The LTC2879X’s tiny 3mm x 3mm footprint is 50% smaller than comparable devices, which helps lower PCB costs and develop condensed design formats.


    The extreme temperature range, rugged fault tolerance, and low-drift, low-leakage circuitry of the LTC2879X device make it well suited for use in oil and gas exploration, industrial control, and aerospace and defense applications. For more information, visit www.analog.com/LTC2879X.
