Part Number:TCA9617B
Hi Team,
I have a question with TCA9617B.
1)Please tell me how to calculate the pull-up resistor values of SDAA/SCLA and SDAB/SCLB.
I confirmed I2C Bus Pullup Resistor Calculation of the document, but it was different from the recommended circuit pull-up of the data sheet of TCA9617B.
2)I want to pull up the EN pin with VCC, but is there a need for resistance?
Is there not a need for an external pull-up resistor due to the internal pull-up resistor?
If a pull-up resistor is required externally, please tell us the recommended resistance value.
3)Please tell me the recommended value of Decoupling Capacitor for VCCA and VCCB.
Best Regards,
Ishiwata
