MAX33071EASA+

MAX33071EASA+ is a half-duplex transceiver with ±65V fault protection. This fault-protected transceiver with high ±65V protection for overvoltage conditions on the communication bus lines, ensuring robust protection in harsh industrial environments. It also incorporates a high ESD protection circuit capable of protecting against ±40kV of ESD human body model (HBM) 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. This device features a receiver enable active-low (RE) input that allows for a low-current shutdown state. 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.
