In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. The pinout of the chip is shown datasheett. 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. 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: When unpressed, the pushbutton has the signal LOW by default. The control terminal enables the input to go to output. This means that either side of the switch can be used as the input.
This establishes sufficient power to the 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.
Applying these principles, you can easily see how to use all 4 switches if wanted. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. Each switch has an input, output, and control terminal. In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control.
It can be obtained cheaply at a number of online electronic retailers.
How to Build a 4066 Quad Bilateral Switch Circuit
datasheef If the pushbuttons are not pressed down, then no signal will appear at the outputs. This enables the signal at the input to go to the output. The most common waveform is a sine wave. As the quad term implies, the is composed up of 4 switches.
When pressed down, the pushbutton makes the signal HIGH. How the Circuit Works So, in order for this circuit to datashheet, the pushbutton must be pressed down for each of the switches.
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. 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. To the inputs of the 2 switches, we feed an analog signal. The has a wide operating voltage of 5VV. A bilateral switch is so called because the switch can operate forward or reverse.
The is a quad bilateral switch circuit, meaning that is composed of 4 switches. A bilateral switch acts as a single pole, single throw switch. The really functions as an analog switch. 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. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. The switches are labeled from 1 to 4.
Without the control or enable switch, there can be no output.
