MAX3082ECSA+T

Product Overview

The MAX3082ECSA+T from Analog Devices Inc./Maxim Integrated is a half-duplex transceiver for RS422 and RS485 serial communication. The device provides one driver and one receiver in a surface-mount 8-SOIC package, with a specified data rate of 115Kbps and receiver hysteresis of 100 mV. It operates from a 4.75 V to 5.25 V supply and has a specified operating temperature range of 0°C to 70°C. The 8-SOIC package is 0.154 in (3.90 mm) wide.

• Surface-mount 8-SOIC package, 0.154 in (3.90 mm) wide

Applications

• Half-duplex RS422 or RS485 serial data links
• Embedded serial communication paths using one driver and one receiver per channel
• 5 V powered serial interfaces where the specified 115Kbps data rate is used

Design & Procurement Notes

Design considerations should focus on matching the specified supply, temperature, package, and protocol behavior to the system. The 4.75 V to 5.25 V supply range and 0°C to 70°C operating range require verification of the board power and final assembly thermal conditions. The 115Kbps data rate and 100 mV receiver hysteresis can be used when assessing timing and input threshold budgets. The 1/1 half-duplex configuration provides one driver and one receiver, so the communication architecture should align with that channel structure. The surface-mount 8-SOIC package, 0.154 in (3.90 mm) wide, affects land pattern and board layout.
