The MC33901/34901 are high speed 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 pin out, 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.
MC34901主要特性:
•Very low current consumption in standby mode
•Automatic adaptation to 3.3 or 5.0 V MCU communication
•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.
