MAX3082ESA+T

Product Overview

The MAX3082ESA+T from Analog Devices Inc./Maxim Integrated is a surface-mount RS422 and RS485 transceiver in an 8-SOIC package. It provides one driver and one receiver for half-duplex serial communication, with a data rate of 115Kbps and a receiver hysteresis of 100 mV. The device operates from a 4.75V to 5.25V supply and supports an ambient temperature range of -40°C to 85°C. The 8-SOIC package measures 0.154 in wide (3.90 mm) and supports surface mounting on printed circuit boards.

Applications

• Serial control and monitoring links in equipment that uses RS422 or RS485 communication standards
• Embedded-system interfaces for exchanging data between controllers and peripheral modules over a half-duplex serial bus
• Instrumentation, automation, and measurement assemblies using a 4.75V to 5.25V supply

Design & Procurement Notes

Design teams selecting the MAX3082ESA+T should confirm that the system supply remains within 4.75V to 5.25V and that the board area supports an 8-SOIC surface-mount package. The half-duplex 1/1 transceiver architecture indicates that transmit and receive operations are not simultaneous, so direction control should be considered in the system design. The 115Kbps data rate and 100 mV receiver hysteresis should be compared against the required communication speed and signal-margin conditions. The operating temperature range of -40°C to 85°C and surface-mount package should be evaluated as part of the overall signal-integrity and thermal design. Exact part number MAX3082ESA+T should be used when specifying the device to preserve the package and electrical characteristics.
