The MAX488ESA+T is an RS-422/ RS-485 interface IC manufactured by Maxim Integrated and designed for use in industrial communications. It features an onboard 3.3V/5V/12V power supply with selectable input/output voltage levels and a slew rate controlled signaling rate. This device has differential inputs/outputs to reduce ground loop errors, allowing for reliable serial data communication. It also incorporates short-to-ground and short-to-VCC protection, as well as thermal shutdown and low power consumption. The MAX488ESA+T is optimized for use with industrial communication networks, meeting the latest ANSI, EIA/TIA, and ITU-T standards. It is suitable for both RS-422 and RS-485 networks, and provides both full-duplex and half-duplex communication.
