Overview
The MAX3485EESA+T is a high-speed RS‑485/RS‑422 transceiver designed for reliable data communication in industrial and embedded systems. It is widely used in factory automation, building automation, and instrumentation, where robust differential signaling and high ESD protection are required. As part of Analog Devices’ Maxim Integrated portfolio, the MAX3485EESA+T offers efficient 3.3 V operation and up to 10 Mbps data rates.
The MAX3485EESA+ is the standard version of the RS-485 transceiver, while the MAX3485EESA+T is the tape-and-reel packaging variant, designed for automated assembly and large-volume production.
Core Parameters
| Parameter | Value | Description |
|---|---|---|
