Product details

What this RS485 transceiver brings to the bus

The MAX3442EESA+T is a half-duplex RS485/RS422 transceiver from Analog Devices, packing one driver and one receiver into an 8-SOIC package. It handles data rates up to 250kbps over a single twisted pair, with the receiver hysteresis set at 25 mV to reject noise on long cable runs.

Supply and temperature envelope

Runs from a single 5V rail (4.75V to 5.25V), which is the standard supply for RS485 bus nodes in industrial control panels.

Package and board integration

The narrow-body SOIC footprint is a common layout for RS485 transceivers — the same board pattern accepts many pin-compatible parts from other vendors, which simplifies second-sourcing during BOM review.

Frequently asked questions

What is the data rate and protocol support for MAX3442EESA+T?

It supports RS422 and RS485 protocols at a maximum data rate of 250kbps in half-duplex mode. The 25 mV receiver hysteresis helps maintain signal integrity on electrically noisy factory-floor bus lines.

What compliance documentation does Analog Devices provide for MAX3442EESA+T?

The part is RoHS3 compliant (2011/65/EU + 2015/863). No UL, IEC, or REACH documentation is listed in the available records.
