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.

In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH.
How to Build a Quad Bilateral Switch Circuit
How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. The most common waveform is a sine wave. The control terminal enables the input to go to output. Each switch has an input, output, and dztasheet terminal.
Fd4066 bilateral switch acts as a single pole, single throw switch. 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.
Without the control or enable switch, there can be no output. The quad bilateral switch chip is a chip that is made up of 4 switches. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.
The has a wide operating voltage of 5VV. V DD and ground, pins 14 and 7, are the power pins. The datasheet for the can be found at the following link: In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. Applying these principles, you can easily see how to use datashdet 4 switches if wanted. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.
If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.
How to Build a 4066 Quad Bilateral Switch Circuit
The really functions as an analog switch. When unpressed, the pushbutton has the signal LOW by default. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. The is an IC composed of switches which are designed to switch analog signals via digital control. So current can flow in one direction and the other direction, depending on which side is the input. 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. Each switch also has a control or enable terminal.
With the dataeheet switch HIGH, then the switch closes and there can be an output. As the quad term implies, the is composed up of 4 switches.
This establishes sufficient power to the chip. The is a pin chip.

It can be obtained cheaply at a number of online electronic retailers. To the inputs of the 2 switches, we feed an analog signal. The pinout of the datawheet is shown below. One place it can be obtained is at Taydaelectronics at the following link: The switches are labeled from 1 to 4.
This enables the signal at the input to go to the output.
If the pushbuttons are not pressed down, then no signal will appear at the outputs.
