[SOLVED] CAN transmitter and CAN receiver chips have different Vcc's

[zenerbjt]

Dear Engineers,
We have a schematic where a ISO1050 CAN transceiver transmits to a CAN receiver (TCAN332).
The ISO1050 has a 5V Vcc, and the TCAN332 has a 3V3 Vcc.

Do you think this will cause problems?

The input common mode range is wide (>> supplies)
and the RX only needs 1.2 - 3V differential input.
There is nothing precluding different supplies.
