Hi all,
we use the TCA9546A with 1.8V on the master side and 3.3V on the slave side.
One use case in our design is that in power saving mode the 3.3V (slave-side) is switched off completely. If I do this with one of the cannels on, it is clear, that there would be a current flow through the device.
But what happens, if all channels are turned off? My assumption is that the gate Voltage will neve the less be at 0V and thus there will be no current flow.
Am I right with this?
Kind regards,
Christian
