MAX33074EASA+

MAX33074EASA+ is a fault-protected RS-485/RS-422 transceiver with high ±65V protection for overvoltage conditions on the communication bus lines, ensuring robust protection in harsh industrial environments. It has ±40V of common-mode range within VCCH (4.5V to 5.5V), exceeding the RS-485 standard of -7V to 12V, making them suitable for electrically noisy environments where different systems have shifting ground levels relative to each other. It incorporate a high ESD protection circuit capable of protecting against ±40kV of ESD human body model (HBM) for driver outputs and receiver inputs. It 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 3V or 5.5V supply voltages across multiple end equipment. Typical applications are industrial automation equipment, home/building automation, agriculture and heavy machinery, power supply and UPS, elevator control, motion controllers.
