MAX33070E/MAX33071E Half-Duplex Transceivers

Analog Devices MAX33070E/MAX33071E RS-485 Half-Duplex Transceivers are fault-protected with high ±65V protection for overvoltage conditions on the communication bus lines, ensuring robust protection in harsh industrial environments. The 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. The MAX33070E/MAX33071E 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).
