MAX13485EESA+T

Product Overview

The MAX13485EESA+T from Analog Devices Inc./Maxim Integrated is a half-duplex transceiver for RS422 and RS485 differential serial communication. It combines one driver and one receiver in a surface-mount 8-SOIC package for board-level integration. The device operates from a 4.75 V to 5.25 V supply, supports a 500 kbps data rate, provides 25 mV of receiver hysteresis, and has an operating temperature range of -40°C to 85°C.

Key Features

• Half-duplex RS422 and RS485 transceiver with one driver and one receiver
• 4.75 V to 5.25 V supply range
• 500 kbps data rate
• 25 mV receiver hysteresis
• Surface-mount 8-SOIC package
• -40°C to 85°C operating temperature range

Applications

• Equipment control and monitoring systems using differential serial communication
• Building automation controllers exchanging data over RS422 or RS485 links
• Test and measurement instruments with half-duplex serial communication interfaces
• Embedded systems requiring a single driver and receiver for a differential serial bus

Design & Procurement Notes

When selecting the MAX13485EESA+T, confirm that the system provides a 4.75 V to 5.25 V supply and that the communication link uses half-duplex RS422 or RS485 signaling with a single driver and one receiver. The 500 kbps data rate should be checked against the required link speed, and the 25 mV receiver hysteresis should be considered when evaluating receiver input behavior in differential signaling. The surface-mount 8-SOIC package and -40°C to 85°C operating temperature range affect PCB layout, thermal management, and environmental suitability.
