[SOLVED] Is SN65HVD1050 (CAN) and SN75176 (RS485) be used with PIC32 VCC=2.8-3.2V

[dhruv_electro]

Our current application needs CAN and RS485 transceivers at 2.8V - 3.2V VCC/VDD.
Our previous designs are of 5V designs and we used SN65HVD1050 as CAN transceiver and SN75176 as RS485 transceiver. They both served fine. But now we are having PIC32MX795F512L as MCU and we are confused about if we can used both of above transceivers or not? We don't have 5V supply rails for current application.

Please guide us if we can use these both transceivers or not? If no please suggest equivalents.

The said interface chips don't work with 3.3V supply. It's quite easy to browse https://www.ti.com/lsds/ti/analog/interface/interface.page for 3.3V CAN and RS485 transceivers fulfilling your design specifications.

Or use the parameter search functions of your favourite catalog distributor.

Please also comment about CAN transceiver. We will definitely see to parametric search. But we required your suggestion, if you have used any for this lower supplies.

the Maxim MAX3051 is worth considering if you are looking for a 3.3V CAN transciver

and the Maxim MAX3362 3.3v RS485 transciver

Hi horace1,

Both of them fulfill my requirement i.e. VCC is as lower as 3.1+V
Meanwhile if anyone have 5V supply available just to have 3.3V data lines here is another good IC:
**broken link removed**(a 3.3 Data lines with 5V supply not suitable for our need.)
