Hello,

It is mentioned 'No Glitch on Power UP' on the datasheet. I understand.

After Power ON, when changing the channel, is there any glitch?

Aoyama-San,

The switch will not connect the channels until a stop bit is sent on the bus. Therefor, there is no glitch from the device itself.

However, if a slave device is pulling the bus low, when the switch connects the channel after the stop bit, the bus will get pulled low as soon as it connects (because the slave is low in this example)
