The MAX3157CAI+T from Analog Devices (formerly Maxim Integrated) is a high Common-Mode Rejection Ratio (CMRR) RS-485 and RS-422 data transceiver. It provides ±50V of isolation, crucial for robust communication in noisy industrial environments. This device operates from a single +5V supply on the logic side, with external capacitors transferring power to the isolated side.
Designed for reliable data transmission, the MAX3157CAI+T is guaranteed to operate at data rates up to 250kbps. It features a true fail-safe receiver that ensures a logic high output even if inputs are open or shorted. The transceiver supports both half- and full-duplex operation, selectable via pins, and includes phase controls to correct for twisted-pair reversal. Drivers are protected against short-circuit currents and excessive power dissipation through thermal shutdown circuitry.
This transceiver is housed in a 28-pin SSOP package, suitable for surface mounting. It offers a low-power shutdown mode, reducing supply current to just 25µA. Applications include industrial controls, level translators, telecommunications, and local area networks.
