Présentation

Description

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.

Equivalent

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.

Pinout

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.

Manufacturer

- Manufacturer: Maxim Integrated Products (now part of Analog Devices).
- What kind of company: A fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits.

Application

- Industrial automation and process control
- PLCs and motor-drive interfaces
- Remote telemetry and data acquisition
- Building automation (HVAC, security, lighting)
- Energy metering and smart-grid equipment
- Instrumentation needing galvanic isolation on differential buses (RS-485/RS-422)

Package

8-pin SOIC (SOP-8) package; +T indicates Tape-on-Reel packaging.
