In order for signals to pass through from the datashert 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. 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.

Each switch has an input, output, and control terminal. 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. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. Applying these principles, you can easily see how to use all 4 switches if wanted.
The has a wide operating voltage of 5VV. 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 also has a control or enable terminal. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. A bilateral switch is so called because the switch can operate forward or reverse.
The is a quad bilateral switch circuit, meaning that datashet composed of 4 switches. The pinout of the chip is shown below. One place it can be obtained is at Taydaelectronics at the following link: The is a pin chip. If the pushbuttons are not pressed down, then no signal will appear at the outputs. Without the control or enable switch, there can be no output. As the quad term implies, the is composed up of 4 switches.
When unpressed, the pushbutton has the signal LOW by default.
When pressed down, the pushbutton makes the signal HIGH. In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. If a signal is datasyeet into the input while the pushbutton is unpressed, no signal will appear at the output. V DD and ground, pins 14 and 7, are the power pins. The really functions as an analog switch. The datasheet for the can be found at the following link: 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. This enables the signal at the input to go to 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.
It xatasheet be obtained cheaply at a number of online electronic retailers.
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 digital signal datwsheet fed into the control or enable terminal. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.
The is datashete IC composed of switches which are designed to switch analog signals via digital control.

This means that either side of the switch can be used as the input. 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 control terminal enables the input to go to output. A bilateral switch acts as a datasheeg pole, single throw switch.

The switches are labeled from 1 to 4. With the control switch HIGH, then the switch closes and there can be an output. The most common waveform is a sine wave. Each switch has a single dafasheet and a single output terminal.
