MAX3082EESA+T

Product Overview

The MAX3082EESA+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 differential serial communication. The data rate is 115Kbps, and the receiver hysteresis is 25 mV. The supply voltage range is 4.75V to 5.25V, and the operating temperature range is -40°C to 85°C. The 8-SOIC package has a 3.90 mm width.

Design & Procurement Notes

For system design, confirm that the supply remains within 4.75V to 5.25V and that the board environment stays within -40°C to 85°C. Board layout should account for the 8-SOIC surface-mount footprint. Because the device is half-duplex with one driver and one receiver, system timing should account for alternating transmit and receive phases. The 115Kbps data rate and 25 mV receiver hysteresis are useful reference points when selecting data rates and evaluating differential input behavior. For procurement, specify the exact manufacturer part number MAX3082EESA+T and verify the package and electrical ratings against the schematic.
