    hi i am using cd4053b as switch between Tx and Rx

    yes.. i am using single sensor to TX and RX, but i have to switch my circuit such a way that, Tx should ON and RX should OFF, and vice versa. for this switching action i am using cd4053b, but its not working, thats why is any pull up resistor is required to connect between supply and terminal...
