A bilateral switch acts as a single pole, single throw switch. So current can flow in one direction and the other direction, depending on which side is the input. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. Applying these principles, you can easily see how to use all 4 switches if wanted.

One place it can be obtained is at Taydaelectronics at the following link: To the inputs of the 2 switches, we feed an analog signal. The is a pin chip. 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. 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.

As the quad term implies, the is composed up of 4 switches. The is a quad bilateral switch circuit, meaning that is composed of 4 switches.


The pinout of the chip is shown below. 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. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.

For this circuit, we are only going to be using 2 of the 4 switches. 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 is so called because the switch can operate forward or reverse. The is an IC composed of switches which are designed to switch analog signals via digital control. The quad bilateral switch chip is a chip that is made up of 4 switches. The control terminal enables the input to go to output.

The switches datashfet labeled from 1 to 4. 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.

This enables the signal at the input to go to the output. The most common waveform is a sine wave. It can be obtained cheaply at a number of online electronic retailers.

Each switch has a single input and a single output terminal. You can view the control terminal as the signal which closes the switch so that the input signal can cross dataaheet to the output. When unpressed, the pushbutton has the signal LOW by default.


Without the control or enable switch, there can be no output.

V DD and dqtasheet, pins 14 and 7, are the power pins. The datasheet for the can be found at the following link: The has a wide operating voltage of 5VV. This means that either side of the switch can be used as the input. Each switch also has a control or enable terminal.

When pressed down, the pushbutton makes the signal HIGH. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.

How the Circuit Works So, in order cd44066 this circuit to work, the pushbutton must be pressed down for each of the 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.

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.
