Each switch has a single input and a single output terminal. This establishes sufficient power to the chip.
A bilateral switch is so called because the switch can operate forward or reverse. The control terminal enables the input to go to output. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.
In this circuit, we will show the basic functionality of the chip by passing analog datawheet through 2 of the switches by digital control. For this circuit, we are only going to be using 2 of the 4 switches. 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 also has a 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. A bilateral switch acts as a catasheet pole, single throw switch.

To the inputs of the 2 switches, we feed an analog signal. One place it can be obtained is at Taydaelectronics at the following link: To the control terminals of the 2 switches, we connect datasheeg pull-down resistor pushbutton circuit. If the pushbuttons are not pressed down, then no signal will appear at cc4066 outputs. 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.
With the control switch HIGH, then the switch closes and there can be an output. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. When pressed down, the pushbutton makes the signal HIGH. The datasheet for the can be found at the following link: When unpressed, the pushbutton has the signal LOW by default. 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.
This enables the signal at the input to go to the output. This means that either side of the switch can be used as the input.
If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.
So by a HIGH digital signal fed into the control terminal, we can pass an analog signal from the input terminal to the datashete terminal of the switch. 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.
How to Build a 4066 Quad Bilateral Switch Circuit
So current can flow in one direction and the other direction, depending on which side is the input. The has a wide operating voltage of 5VV. The is a pin chip. It can be obtained cheaply at a number of online electronic retailers. Each switch has an input, output, and control terminal. V DD and ground, pins 14 and 7, are the power pins.
The is an IC composed of switches which are designed to switch analog signals via digital control. The really functions as an analog switch.
As the quad term implies, the is composed up of 4 switches. The switches are labeled from 1 to 4.

Applying these principles, you can easily see how to use cv4066 4 switches if wanted. 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 pinout of the chip is datashewt below. The most common waveform is a sine wave. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.
The quad bilateral switch chip is a chip that is made up of 4 switches.
