MAX33070EASA RS-485 Transceiver with 65V Fault Protection 500kbps Data Rate and Wide Operating Temperature Range

MAX33070 is fault-protected RS-485/RS-422 transceivers with high ±65V protection for overvoltage conditions on the communication bus lines, ensuring robust protection in harsh industrial environments. All devices have ±40V of common-mode range (CMR) 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.

They also incorporate 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). Each 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.
