 The MAX33076-9E is a family of robust quad channel RS-485/422 receivers with high CMR (common mode range), high fault protection, and high ESD for harsh electrical environments. This family operates from a supply range of +3.3V or +5.0V.

These devices feature a high CMR of ±25V, which helps in reception of messages when the ground planes between two nodes have large differences or large external interference from motors or other electrical noise sources. These parts have extended fault protection of ±65V where the data lines are protected from accidental shorts to local power supplies. A high ESD HBM (human body model) of ±25kV also protects the data lines from ESD strikes either during production or in the field.
