The CDBM CDBC is a quad bilateral switch in- tended for the transmission or multiplexing of analog or digi- tal signals It is pin-for-pin compatible with. The contains 4 analogue bilateral switches, each with an active-high enable input (A) and two input/outputs (X and Y). When the enable input is set high. Page 1.

The is an IC composed of switches which are cd4606 to switch analog signals via digital control. This enables the signal at the input to go to the output. So by a HIGH digital signal fed datassheet the control terminal, we can pass an analog signal from the input terminal to the output terminal of the switch. For this circuit, we are only going to be using 2 of the 4 switches. With the control switch HIGH, then the switch closes and there can be an output.

The control terminal enables the input to go to output. 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 the pushbuttons are not pressed down, then no signal will appear at the outputs. First, 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. 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. 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.

The most common waveform is a sine wave. This establishes sufficient power to the chip. The really functions as an analog switch. When unpressed, the pushbutton has the signal LOW by default. When pressed down, the pushbutton makes the signal HIGH. One place it can datasheett obtained is at Taydaelectronics at the following link: 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.

The has a wide operating voltage of 5VV. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. Each switch has a single input and a single output terminal.

If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.

How to Build a Quad Bilateral Switch Circuit

Without the control or enable switch, there can be no output. To the inputs of the 2 switches, we feed an analog signal. The is a pin chip. A bilateral switch acts as a single pole, single throw switch. This means that either side of the switch can be used as the input. As cv4066 quad datashset implies, the is composed up of 4 switches.


To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. The quad bilateral switch chip is datasbeet chip that is made up of 4 switches. So current can flow in one direction and the other direction, depending on which side is the input. It can be obtained cheaply at a number of online electronic retailers. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.

How to Build a 4066 Quad Bilateral Switch Circuit

Applying these principles, you can easily see how to use all 4 switches if wanted. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.

V DD and ground, pins 14 and 7, are the power pins. Each switch also has a control or enable terminal.

The datasheet for the can be found at the following link: Each switch has an input, output, and control terminal. The switches are labeled datazheet 1 to 4.

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. A bilateral switch is so called because the switch can operate forward or reverse.
