First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.

The datasheet for the can be found at the following link: In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. This establishes sufficient power to the chip. When pressed down, the pushbutton makes the signal HIGH. When unpressed, the pushbutton has the signal LOW by default.

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 has an input, output, and control terminal. The most common waveform is a sine wave.

So by a HIGH digital signal fed into the control terminal, we can pass dstasheet analog signal from the input terminal to the output terminal of the switch. 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. What this means is we feed an analog signal into the input of the switch and it reaches the datashwet only if a HIGH digital signal is fed into the control or enable terminal.


The has a wide operating voltage of 5VV. With the control switch HIGH, then the switch closes and there can be an output. To the inputs of the 2 switches, we feed an analog signal.

The is a quad bilateral switch circuit, meaning that is composed of 4 switches. For this circuit, we are only going to be using 2 of the 4 switches. The control terminal enables the input to go to output. How the Circuit Works So, in order for this circuit to work, the pushbutton must fatasheet pressed down for each of the switches. Without the control or enable switch, there can datzsheet no output. To the control terminals of the 2 switches, fd4066 connect a pull-down resistor pushbutton circuit.

In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. The is an IC composed of switches which are designed to switch analog signals via digital control.

A bilateral switch is so called because the switch can operate forward or reverse. You can view the control terminal as the signal which closes the switch so that the dahasheet signal can cross over to the output. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.


One place it can be obtained is at Taydaelectronics at the following link: The really functions as an analog switch. Each switch has a single input and a single output terminal. This means that either side of the switch can be used as the input. If datsaheet pushbuttons are not pressed down, then no signal will appear at the outputs.

So current can flow in one direction and the other direction, depending on which side is datasjeet input. 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.

V DD and ground, pins 14 and 7, are the power pins. The pinout of the chip is shown below.

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

This enables the signal at the input to go to the output. The switches are labeled from 1 cd406 4. A bilateral switch acts as a single pole, single throw switch. The is a pin chip. The quad bilateral switch chip is a chip that is made up of 4 switches.

It can be obtained cheaply at a number of online electronic retailers.
