The MC33901/34901 are SMARTMOS high-speed （up to 1.0 Mbits/s） CAN transceivers providing the physical interface between the CAN protocol controller of an MCU and the physical dual wires CAN bus. They are packaged in an 8-pin SOIC with market standard pinout， and offer excellent EMC and ESD performance without the need for external filter components. Four devices variations are available： - Versions with and without CAN bus wake-up. - Versions with and without TXD dominant protection. Features ? Very low-current consumption in standby mode ? Compatible with 3.3 V or 5.0 V MCU interface ? Standby mode with remote CAN wake-up on some versions. ? Pin and function compatible with market standard Cost efficient robustness： ? High system level ESD performance ? Very high electromagnetic Immunity and low electromagnetic emission without common mode choke or other external components. Fail-safe behaviors： ? TXD Dominant timeout， on the 33901 version. ? Ideal passive when unpowered， CAN bus leakage current 《10 ?A. ? VDD and VIO monitoring
