MAX3157EAI Description

Short technical summary and product information.

The MAX3157EAI from Analog Devices (formerly Maxim Integrated) is a high CMRR RS-485/RS-422 data communications interface providing ±50V isolation. This hybrid microcircuit is powered by a single +5V supply on the logic side, with external capacitors transferring power to the isolated side.

 

Designed for robust communication, the MAX3157EAI includes one transmitter and one receiver, guaranteed to operate at data rates up to 250kbps. It features driver short-circuit current limiting and thermal shutdown protection. The receiver input includes a true fail-safe feature, ensuring a logic high output even if inputs are open or shorted.

 

This transceiver supports both half- and full-duplex operation and offers independently programmable receiver and transmitter output phase control. It is a low-cost replacement for opto-isolated transceivers and is suitable for applications such as industrial controls, level translators, telecommunications, and local area networks. The device is available in a 28-pin SSOP package and is slew rate limited to reduce EMI.
