MAX33040E CAN Transceiver Analog Devices Inc. MAX33040E CAN Transceiver is a +3.3V Control Area Network (CAN) transceiver with integrated protection for industrial applications. This device has extended ±40V fault protection on CANH and CANL for equipment where overvoltage protection is required. This device also incorporates high ±40kV ESD (Electrostatic Discharge) HBM (Human Body Model) and an input Common-Mode Range (CMR) of ±25V on CANH and CANL, exceeding the ISO 11898-2 CAN standard of -2V to +7V. These features make the MAX33040E CAN Transceiver well suited for applications where there is moderate electrical noise that can influence the ground levels between two nodes or systems. This device also includes a shut-down pin and a multifunction standby pin.
