V DD and ground, pins 14 and 7, are the power dd4066. When pressed down, the pushbutton makes the signal HIGH. This enables the signal at the input to go to the output. The switches are datashfet from 1 to 4. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. 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. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. Each switch also has a control or enable terminal. The has a wide operating voltage of 5VV.

It can be obtained cheaply at a number of online electronic retailers. The control terminal enables the input to go to output.

When unpressed, the pushbutton has the signal LOW by default. For this circuit, we are only going to be using 2 of the 4 switches. The pinout of the chip is shown below. So current can flow in one direction and the other direction, depending on which side is the input. 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.


The is a pin chip. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.

The datasheet for the can be found at the following link: One place it can be obtained is at Taydaelectronics at the following link: With the control switch HIGH, then the switch closes and there can be an output. This means that either side of the switch can be used as the input. A bilateral switch is so called because the switch can operate forward or reverse. Cd406 switch has an input, output, and control terminal.

How to Build a 4066 Quad Bilateral Switch Circuit

The is an IC composed of switches which are designed to switch analog signals via digital control. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. If the pushbuttons are not pressed down, then no signal will appear at the outputs. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. The most common waveform is a sine wave.

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. As the quad term implies, the is composed up of 4 switches. Applying these principles, you can datasheer see how to use all 4 switches if wanted.


First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. 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. To the inputs of the 2 switches, we feed an analog signal. 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.

Each switch has a single input and a single output terminal. A bilateral switch acts as a single pole, single throw switch. 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 the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.

This establishes sufficient power to the chip. The really functions as an analog switch.
