Hye..
I want to ask who can show me how to connect bilateral switch 4066 in multisim??

PLZZ
 

In the simplest sense, the 4066 contains 4 switches which are similar to relays.

Each switch is governed by its control pin (as you pull it high or low).
The control pins are referenced to ground inside the IC. They do not need a return path. (On the other hand a relay coil does need a return path).

Each I/O pair can carry current in either direction. In other words, input of switch A is interchangeable with output of switch A. Etc.
The 4066 is unusual in having this capability.
 



Can you see my image... can you tell me whats wrong with the circuit...
 

Pin 14 of U1 and U2 should go to Vdd (+5V) and both pin 7 should go to GND.(0V). Your clock pulse should go to pin 13 of both U1 and U2 as they are identical.

Connect a oscilloscope to the 3 points as in my schematic and you can get more info on what your circuit is doing.

See my attachment in proteus.
