Each switch has an input, output, and control terminal. 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.
V DD and ground, pins 14 and 7, are the power pins. This establishes sufficient power to the chip. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output.
Each switch also has a control or enable terminal. Without the control or enable switch, there can be no output. This means that either side of the switch can be used as the input. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. Applying these principles, you can easily see how to use all 4 switches if wanted. The control terminal enables the input to go to output.
The switches are labeled from 1 to 4. The has a wide operating voltage of 5VV. The quad bilateral switch chip is a chip that is made up of 4 switches. The really functions as an analog switch. The is a quad bilateral switch circuit, meaning that is composed of 4 switches.
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 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.
So current can flow in one direction and the other direction, fd4066 on which side is the input. For this circuit, we are only going to be using 2 of the 4 switches. If the pushbuttons are not pressed down, then no signal will appear at the outputs. The most common waveform is a sine wave. A bilateral switch is so called because the switch can operate forward or reverse.
How to Build a 4066 Quad Bilateral Switch Circuit
The pinout of the chip is shown below. It can be obtained cheaply at a number of online electronic retailers. One place it can be obtained is at Taydaelectronics at the following link: The is an IC composed of switches which are designed to switch analog signals via digital datsaheet. 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.
The is a pin chip.

When pressed down, the pushbutton makes the signal HIGH. As the quad term implies, the is composed up of 4 switches. 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 single input and cf4066 single output terminal.
To the control terminals of the 2 ddatasheet, we connect a pull-down resistor pushbutton circuit. In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control.
When unpressed, the pushbutton has the signal LOW by default. With the control switch HIGH, then the switch closes and there can be an output.
A bilateral switch acts as a single pole, single throw switch. This enables the signal at the input to go to the 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 cd466 signal is fed into the control or enable terminal.
