ILX3485DT – RS-485/RS-422 Transceiver IC

Description

The ILX3485 is a low-power transceiver IC designed for RS-485 and RS-422 communication, featuring a driver and a receiver. It allows transmission at up to 5Mbps with unrestricted driver slew rates. Operating on a single 3.3V supply, it has low quiescent current (300uA), supports a wide common-mode input voltage range (-7V to +12V), and includes features like current limiting, thermal shutdown for driver overload protection, and fail-safe receiver input. The IC is efficient, with three-state outputs and short-circuit protection, making it suitable for various applications with up to 32 transceivers on the bus.
