One place it can be obtained is at Taydaelectronics at the following link: The most common waveform is a sine wave.

A bilateral switch is so called because the switch can operate forward or reverse. When unpressed, the pushbutton has the signal LOW by default. This means that either side of the switch can be used as the input.

Without the control or enable switch, there can be datashret output.

To the inputs of the 2 switches, we feed an analog signal. 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. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.


V DD and ground, pins 14 and 7, are the power pins. 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.

When pressed down, the pushbutton makes the signal HIGH. 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.

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. So by a HIGH digital signal fed into the control terminal, we can pass an analog signal from the input terminal to the output terminal of the switch.

The quad bilateral switch chip is a chip that is made up of 4 switches. The datasheet for the can be found at the following link: Applying these principles, you can easily see how to use all 4 switches if wanted.

How to Build a 4066 Quad Bilateral Switch Circuit

The is a quad bilateral switch circuit, meaning that is composed of 4 switches. In order for signals to pass through from the input side to the output side, eatasheet control or enable terminal must be HIGH. As the quad term implies, the is composed up of 4 switches. In this circuit, we will show the basic functionality of datasheef chip by passing analog signals through 2 of the switches by digital control.


A bilateral switch acts as a single pole, single throw switch. The control terminal enables the input to go to output. For this circuit, we are only going to be dstasheet 2 of the 4 switches.

This enables the signal at the input to go to the output. This establishes sufficient power to the chip. So current can flow in one direction and the other direction, depending on which side is the input.

To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. The switches are labeled from 1 to 4.

If the pushbuttons are not pressed down, then no signal will appear datasheet the outputs. The pinout of the chip is shown below. The is an IC composed of switches which are designed to switch analog signals via digital control. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. Each switch has a xd4066 input and a single output terminal.

Each switch also has a control or enable terminal. The is a pin chip. Each switch has an input, output, and control terminal.
