Product details

RS422/RS485 full-duplex transceiver at 2.5 Mbps

The MAX491CSD+ is a single-channel RS422/RS485 transceiver from Analog Devices, supporting full-duplex communication at 2.5 Mbps over a single twisted pair or four-wire bus. The 70 mV receiver hysteresis provides noise immunity on long cable runs where ground potential differences can introduce several hundred millivolts of offset between nodes.

Frequently asked questions
