there is a MUX requirement and the function is as I described below:
1. Logic chart
2. the SET PIN could be 0~12V.
3. the price should be as low as possible.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thank you for providing those details and diagram.
My best recommendation for a single 2:1 mux is TMUX1247, which supports supply voltage range of 1.08 - 5.5V and logic control input (SEL) of 0 - 5.5V. TMUX1247 features 1.8V logic and fail-safe logic.
I would like to point out that TMUX1247 and similar devices use the following truth table:
Is it possible to interchange the IN1 and IN2 pins in your system?
In reply to Kate Dickson:
Thanks for your recommendation:
1. It is possible to interchange the IN1 and IN2 pins in my system
2. from the datasheet, the voltage range of SEL is -0.5V~6V. it seem that it can't undertake the 12V. would you have any idea for solve this?
Thanks for your response.
TMUX6119 is a 2:1 mux that supports a positive supply voltage (VDD) of 5 - 16.5V and a digital input (SEL) pin voltage of 0V to VDD. TMUX6119 also includes an enable pin, allowing for a third state where both switches are OFF.
This is a good solution if your power supply is 12V or more.
