The MAX3072EIM/TR is a level-shifting, low-voltage differential signaling (RS-485/RS-422) transceiver IC manufactured by HGSEMI. It is designed for communications on multipoint networks up to 34 nodes in half-duplex mode. It has an auto-directional feature that allows it to detect and control direction of data flow. It is available in a small 8-pin SOIC package, making it suitable for applications with space constraints. It features a -7V to +12V signal range with fail-safe feature, and is compliant with the electrostatic discharge (ESD) requirements of the JEDEC standards JESD78 and JESD22. The device is RoHS compliant, lead-free, and does not contain any hazardous substances.
