MAX3082ECSA+

Product Overview

The MAX3082ECSA+ from Analog Devices Inc./Maxim Integrated is a half-duplex RS422 and RS485 transceiver for serial communication links. It integrates one driver and one receiver in an 8-SOIC surface-mount package, supports a 4.75 V to 5.25 V supply range, and provides a 115 Kbps data rate. The receiver includes 100 mV hysteresis. The device operates from 0°C to 70°C and is suitable for systems that use a single transmit/receive path for serial data exchange.

Key Features

• RS422 and RS485 protocol support for half-duplex serial communication.
• One driver and one receiver integrated in an 8-SOIC surface-mount package.
• 115 Kbps data rate with 100 mV receiver hysteresis.
• 4.75 V to 5.25 V supply range and 0°C to 70°C operating temperature range.
• 8-SOIC package with 0.154" (3.90mm) body width.

Applications

• Serial communication in equipment control and monitoring links.
• Instrumentation and measurement equipment data links using RS422 or RS485.
• Sensor and actuator communication links with half-duplex serial operation.
• Serial data acquisition systems requiring one transmit/receive path.

Design & Procurement Notes

Designers should confirm that the 8-SOIC footprint, 0.154" (3.90mm) body width, and surface-mount assembly process match the PCB layout. The 4.75 V to 5.25 V supply range requires a supply within that window, and the 0°C to 70°C operating range should be checked against the ambient environment. Because the device is a half-duplex transceiver with one driver and one receiver, the system must use a single transmit/receive path. The 115 Kbps data rate and 100 mV receiver hysteresis should be evaluated against the selected RS422 or RS485 protocol requirements.
