The MAX13443EASA+T is an 80V fault protected RS-485 half-duplex transceiver with foldback current limit manufactured by Analog Devices. It is designed to provide reliable data transmission over balanced differential signaling data lines, up to 250kbps, with higher system noise immunity and low EMI. This device supports data cables up to 50m in length at 2.5Mbps. It features integrated ESD protection and will actuate if any single wire is short-circuited to power or ground. It also incorporates strong fault protection to ensure circuits survive faults in differential lines. Additionally, it features high common mode input voltage levels, fail safe receiver inputs, and independent receiver input slew rate control.
