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. 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 order eatasheet 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, depending on which side is the input. The datasheet for the can be found at the following link: The is a quad bilateral switch circuit, meaning that is composed of 4 switches.

As the quad term implies, the is composed up of 4 switches. This establishes sufficient power to the chip. The quad bilateral switch chip is a chip that is made up of 4 switches.

If the pushbuttons are not pressed down, then no signal will appear at the outputs. 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: It can be obtained cheaply at a number of online electronic retailers.

The most common waveform is a sine wave. Each switch also has a control or enable terminal. For datashete circuit, we are only going to be using 2 of the 4 switches.

The is a pin chip. This means that either side of the switch can be used as the input. A bilateral switch acts datashest a single pole, single throw switch. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. 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. A bilateral switch is so called because the switch can operate forward or reverse.

Each switch has a single input and a single output terminal. 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 has a wide operating voltage of 5VV.

In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.


When pressed down, the pushbutton makes the signal HIGH. 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 control terminal enables the input to go to output. Dataseet, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. The pinout of the chip is shown below.

In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. Without the control or datxsheet switch, there can be no output. Each switch has an input, output, and control terminal.

How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. This enables the signal at the input to go to the output. When unpressed, the pushbutton has the signal LOW by default.

The switches are labeled from 1 to 4. With the control switch HIGH, then the switch dataxheet and there can be an output.
