MC34901SEF (NXP)

The MC34901SEF is a high-speed CAN Transceiver providing the physical interface between the CAN protocol controller of an MCU and the physical dual wires CAN bus. It offers excellent EMC and ESD performance without the need for external filter components. It meets the ISO 11898-2 and ISO11898-5 standards and have low leakage on CAN bus while unpowered. It is supplied from VDD and VIO, to allow automatic operation with 5 and 3.3V microcontrollers. The device input pin to control the CAN bus level. In the application, this pin is connected to the microcontroller transmit terminal. In normal mode, when TXD is high or floating, the CANH and CANL drivers are OFF, setting the bus in a recessive state. When TXD is low, the CANH and CANL drivers are activated and the bus is set to a dominant state.
