MAX3157 Datasheet (Maxim) - High CMRR RS-485 Transceiver

MAX3157, High CMRR RS-485 Transceiver

The MAX3157 is a high CMRR RS-485/RS-422 data-communications interface providing ±50V isolation in a hybrid microcircuit.

A single +5V supply on the logic side powers both sides of the interface, with external ±50V capacitors transferring power from the logic side to the isolated side.
