Hi Team，

Is the following schematic design possible? VCCA is the same as VCCB, this circuit is used as a switch. Thank you.

Best regards,

Looks OK, but I do not know anything about the four signals (the TXS's internal pull-up resistors might conflict with any external pull-down resistors).

Why not use an actual switch like the SN74CBTLV3125‌/6, which would be cheaper?

Hey Ansel,

What interface is this for, and exactly what is trying to be achieved with this device?
