When unpressed, the pushbutton has the signal LOW by default. Each switch also has a control or enable terminal. This establishes sufficient power to the chip.

Applying 4066vp principles, you can easily see how to use all 4 switches if wanted. V DD and ground, pins 14 and 7, are the power pins. As the quad term implies, the is composed up of 4 switches. This enables the signal at the input to go to the output. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. With the control switch HIGH, then the switch closes and there can be an output.

If the pushbuttons are not pressed down, then no signal will appear at the outputs. When pressed down, the pushbutton makes the signal HIGH.


First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. So by a HIGH digital signal fed datawheet the control terminal, we can pass an analog signal from the input terminal to the output terminal of the switch. It can be obtained cheaply at a number of online electronic retailers.

In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. The control terminal enables the input to go to output.

Each switch has an input, output, and control terminal. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.

Each switch has a single input and a single output terminal. The most common waveform is a sine wave. What this means is we feed an analog signal into the input of the switch and it reaches the output only if a HIGH digital signal is fed into the control or enable terminal.

The pinout of the chip is shown below. Without the control or enable switch, there can be no output. The quad bilateral switch chip is a chip that is made up of 4 switches.

You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. The has a wide operating voltage of 5VV. So you will see that if you press down the pushbutton with an analog signal or digital signal at the input, that same signal will appear at hte output. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH.


In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. To the inputs of the 2 switches, we feed an analog signal. A bilateral switch acts as a single pole, single throw switch. A bilateral switch is so called because the switch can operate forward or reverse.

The really functions as an analog switch. This means that datashest side of the switch can be used as the input. The is a pin chip.

For this circuit, we are only going to be using 2 of the 4 switches. The datasheet for the can be found at the following link: How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.

So current can flow in one direction and the other direction, depending on which side is the input. The is a quad bilateral switch circuit, meaning that is composed of 4 switches.
