Other Parts Discussed in Thread: SN74LVC2G53

as pspice model is not available for SN74LVC2G53. i want to use it in my circuit. Biasing the IC under 5V vcc and Gnd. sensor is attached to the COM pin of demux and Y1, Y2 are connected to different ADC. IHN pin is hardwired to GND and A(pin 5) can be high or low. now my question is do i need some thing else to interface or just this setup is enough? signal from sensor can be of 1kHz with 10m to 5 volts.

    Yes, this setup will work as long as you consider the following:

    -Make sure there is no condition where the current limits of the switch are violated in the application.

    -The switch will act like a resistor when the path is connected (this is true for all analog switch ICs). The resistance may be up to ~15 ohms in this application. As long as the series resistance of 15 ohms will not affect your ADC reading, your application should work fine.
