MAX3157CAI Description

Short technical summary and product information.

The MAX3157CAI is a high CMRR RS-485/RS-422 data communications interface providing ±50V isolation. It operates from a single +5V supply, with external capacitors transferring power to the isolated side. Each device includes one transmitter and one receiver, guaranteed to operate at data rates up to 250kbps.

 

Key features include true fail-safe receiver operation, pin-selectable full/half-duplex modes, and phase controls for correcting twisted-pair reversal. The transceiver also offers a low-power shutdown mode drawing only 25µA and thermal shutdown protection for drivers.

 

Applications for the MAX3157CAI include industrial controls, level translators, telecommunications, and local area networks. It is designed as a low-cost replacement for opto-isolated transceivers and is supplied in a 28-pin SSOP package suitable for surface mounting.

 

This transceiver is designed for robust communication in demanding environments. Its isolation capabilities protect sensitive circuitry from voltage transients, while features like slew rate limiting reduce EMI emissions.
