TCA9548A: Electrical characteristics of SC*/SD*

Thank you for answering,Clemens ＆ Alex

When the VCC power is ON and the pull up power on the SC*/SD* side is OFF,
is it possible for the current on the SCL/SDA side to flow to the SC*/SD* side?
What happens when the VCC power supply is OFF?

Best Regards,

Hi Kakeru,

Are you asking if the SC*/SD* pins are pulled to 0V what will the current flow be? If so, there is no current flow. 

When the device/supply is powered off, then the pass FET is off, and no current can flow through it. 

Regards,

Alex

>Are you asking if the SC*/SD* pins are pulled to 0V what will the current flow be? If so, there is no current flow. 
This occurs when SC*/SD* pins become HiZ.

When the device/power supply is turned on, even if either the SC*/SD* side or the SCL/SDA side becomes HiZ, will no current flow to the HiZ side?
