Each switch has a single input and a single output terminal.

The is an IC composed of switches which are designed to switch analog signals via digital control. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.

The switches are labeled from 1 to 4. With the control switch HIGH, then the switch closes and there can be an output. The most common waveform is datasheef sine wave. The control terminal enables the input to go to output. Catasheet place it can be obtained is at Taydaelectronics at the following link: Without the control or enable switch, there can be no output.


The pinout of the chip is shown below. To the inputs of the 2 switches, we feed an analog signal. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.

How to Build a Quad Bilateral Switch Circuit

The really functions as an analog switch. As the quad term implies, the is composed up of 4 switches. If the pushbuttons are not pressed down, then no signal will appear at the outputs.

In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. How to Build a Quad Bilateral Switch Circuit In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.

Each switch also has a control or enable terminal.

This means that either side of the switch can be used as the input. When unpressed, the pushbutton has the signal LOW by default. So current can flow in one direction and the other direction, depending on which side is the input.

In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. A bilateral switch acts as a single pole, single throw switch. V DD and ground, pins 14 and 7, are the power pins.


Applying these principles, you can easily see how to use all 4 switches if wanted.

It can be vd4066 cheaply at a number of online electronic retailers. 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. When pressed down, the pushbutton makes the signal HIGH.

The has a wide operating voltage of 5VV. The datasheet for the can be found xatasheet the following link: In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. This establishes sufficient power to the chip.

How to Build a 4066 Quad Bilateral Switch Circuit

To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. So you will see that if you press down the pushbutton with an analog signal or digital signal at the input, that datzsheet signal will appear at hte output. The is a pin chip.
