The MAX33042E is a +5V CAN transceiver with integrated protection for industrial applications. This device has extended ±40V fault protection for equipment where overvoltage protection is required. It also incorporates high ±40kV ESD Human Body Model (HBM) protection and an input common-mode range (CMR) of ±25V, exceeding the ISO 11898-2 CAN standard of -2V to +7V. This makes it well suited for applications where there is moderate electrical noise that can influence the ground levels between two nodes or systems.

This device operates at a high-speed CAN data rate, allowing up to 4Mbps on short distance networks. Maximum speed on large networks may be limited by the number of nodes, the type of cabling used, stub length, and other factors. The MAX33042E includes a dominant timeout to prevent bus lockup caused by controller error or by..
