Hello,

I'm checking the TCA9539-Q1 to apply this on my ECU.

I couldn't find the recommended the bypass capacitance on VCC,

Could you let me know this value or related document to calculate the bypass capacitance?

Low ESL/ESR (i.e., short traces and small package) are more important than the actual value. Typically, you'd use 100 nF.

Hey Hwangsu,

In addition to Clemens' response, please also see section 10.1- 10.2 of the datasheet for more information for layout guidelines. Let us know if you have any further questions/ concerns!

Regards,

Jack
