IF THE VI0 pin is active i.e 3.3v and 5 volt for vcc is not active, will the transceiver work. But its told that Vio pin will switch on low-power receiver.

Hi Shubham,

The TJA1044/3 offers the same functionality as the TJA1044 but with additional VIO supply and a Low Power Receiver supllied out of VIO.

This offers a low power Standby Mode where the VCC supply can be switched off while the bus wake up capability keeps active via the Low Power Receiver.
