MAX3157EAI+T

MAX3157EAI+T is a Maxim IIntegrated RS-422/RS-485 transceiver. It provides a differential line driver and receiver in one package, enabling a microcontroller to drive and read a twisted-pair RS-422/RS-485 network. The device supports a single-ended control interface: DI (data input) to the driver, RO (data output) from the receiver, and direction control via DE (driver enable) and RE (receiver enable). It includes a failsafe receiver so the output remains a known logic level when the bus is idle, open, or shorted, and typically offers tri-state outputs and protection features for robust operation. The EAI suffix indicates industrial-temperature, RoHS-compliant packaging, while +T denotes Tape-and-Reel packaging. Common applications include industrial automation, building controls, and instrumentation networks. For exact electrical specs (data rate, voltage ranges, drive strength, and current limits), consult the official MAX3157E datasheet.

I don’t have live cross-reference data. To give exact equivalents, please provide MAX3157EAI+T’s function and key specs (bus type, number of channels, data rate, supply voltage, package) or share the datasheet link. With those, I can list precise cross-references from TI, Analog Devices, NXP, etc., such as RS-485/RS-422 transceiver families.

Pin count: 28 pins (28-pin package such as TQFP/MSOP).
Function: Quad RS-485/RS-422 differential transceiver. It provides four driver/receiver channels with DI/RO data paths and DE/RE control for each channel, enabling multi-drop differential serial links.
