The is a quad bilateral switch circuit, meaning that is composed of 4 switches. How to Build a Quad Bilateral Dztasheet Circuit In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. What this means is we feed an analog signal datasheeet 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 is a pin chip.

How to Build a 4066 Quad Bilateral Switch Circuit

If the pushbuttons are not pressed down, then no signal will appear at the outputs. The quad bilateral switch datasueet is a chip that is made up of 4 switches. In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. Each cv4066 has a single input and a single output terminal. This datasbeet that either side of the switch can be used as the input. Each switch also has a control or enable terminal.

The switches are labeled from 1 to 4. 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.

With the control switch HIGH, then the switch closes and there can be an output. Applying these principles, you can easily see how to use all 4 switches if wanted. When unpressed, the pushbutton has the signal LOW by default. This enables the signal at the input to go to the output.

The datasheet for the can be found at the following link: In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. As the quad term implies, the is composed up of 4 switches. The is an IC composed of switches which are designed to switch analog signals via digital control.

The has a wide operating voltage of 5VV. This establishes sufficient power to the chip. A bilateral switch is so called because the switch can operate forward or reverse. For this circuit, we are only going to be using 2 of the 4 switches. The most common waveform is a sine wave. One place it can be obtained is at Taydaelectronics at the following link: 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 datasheeh control terminal, we can pass an analog signal from the input terminal to the output terminal of the switch.


To the inputs of the 2 switches, we feed an analog signal. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.

To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. The really functions as an analog switch. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.

The pinout of the chip is shown below.

cd40066 V DD and ground, pins 14 and 7, are the power pins. So current can flow in one direction and the other direction, depending on which side is the input. Each switch has an input, output, and control terminal. A bilateral switch acts as a single pole, single throw switch.

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 daatsheet, to ground.

The control terminal enables the input to go to output. It can be obtained cheaply at a number of online electronic retailers. Without the control or enable switch, there can be no output.
