MAX33072EASA+

MAX33072EASA+ is a polarity invert RS-485 half-duplex transceiver with ±65V fault protection. This device has ±40V of common-mode range (CMR) within VCCH (+4.5V to +5.5V), exceeding the RS-485 standard of -7V to +12V, suitable for electrically noisy environments where different systems have shifting ground levels relative to each other. It also incorporates a high ESD protection circuit capable of protecting against ±40kV of ESD HBM (human body model) for driver outputs and receiver inputs (A and B data lines). This device contains one driver and one receiver and operates over the +3V to +5.5V supply range, making it convenient for designers to use one part with either +3.3V or +5V supply voltages across multiple end equipment. It is used in applications such as industrial automation equipment, home and building automation, agriculture and heavy machinery, power supply and UPS, elevator control, motion controllers.
