Hello I use the S32K148 micro controller supplied with 3.3V which comunique with a Can tranceiver supplied with 5V
the voltage at the terminal of A1 and A2 is 2.8V
B1 and B2 output a voltage which oscillates between 2.8V and 5V.
is it normal to behave like this?
I share with you my schematic as an attachment
thank you for your support
Thank for your answer.
I have 100nf 16V capacitor for VCCA and VCCB
i dont have a pull up in A/B
shoud place a capacitor and if the valu of capacitor is OK?
what is the valu of A/B pull up resistor ?
