The pinout of the chip is shown below. For this circuit, we are only going to be using 2 of the 4 switches.
The quad bilateral switch chip is a chip that is made up of 4 switches. Each switch also has a control or enable terminal. 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 is a quad bilateral switch circuit, meaning that is composed of 4 switches. The datasheet for the can be found at the following link: Each switch has a single input and a single output terminal. So current can flow in one direction and the other direction, depending on which side is the input.
To the inputs of the 2 switches, we feed an analog signal. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.
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. The has a wide operating voltage of 5VV. To the control terminals of the 2 datwsheet, we connect a pull-down resistor pushbutton circuit. The switches are labeled from 1 to 4.
This enables the signal at the input to go to the output. The control terminal enables the input to go to output. 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. In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of datasheer switches by digital control.
When pressed down, the pushbutton makes the signal HIGH. What this means is we feed an analog signal into the input of the switch and vatasheet reaches the output only if a HIGH digital signal is fed into the control or enable terminal. If dafasheet pushbuttons are not pressed down, then no signal will appear at the outputs.
When unpressed, the pushbutton has the signal LOW by default. As the quad term implies, the is composed up 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. 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. The is a pin chip. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the daasheet. The really functions fd4066 an analog switch. The is an IC composed of switches which are designed to switch analog signals via digital control.
One place it can be obtained is at Taydaelectronics at the following link: This establishes sufficient power to the chip. A bilateral switch dagasheet as a single pole, single throw switch.
How to Build a 4066 Quad Bilateral Switch Circuit
Without the control or enable switch, there can be no output. V DD and ground, pins 14 and 7, are the power pins. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.
This means that either side of the switch can be used as the input. The most common waveform is a sine wave. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.
