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.

How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. The quad bilateral switch chip datasheet a chip that is made up of 4 switches. For this circuit, we are only going to be using 2 of the 4 switches. This enables the signal at the input to go to the output.
The switches are labeled from 1 to 4. To the inputs of the 2 switches, we feed an analog signal. With the control switch HIGH, then the switch closes and there can be an output.
How to Build a 4066 Quad Bilateral Switch Circuit
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. The is an IC composed of switches which are designed to switch analog signals via digital control. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. This establishes sufficient power to the chip.
As the quad term implies, the is composed up of 4 switches.
One place it can be obtained is at Taydaelectronics at the following link: V DD and ground, pins 14 and 7, are the power pins. The most common waveform is a sine wave.
Without the control or enable switch, there can be no output. Applying these principles, you can easily see how to use all 4 switches if wanted. A bilateral switch acts as a single pole, single throw switch.
How to Build a Quad Bilateral Switch Circuit
When unpressed, the pushbutton has the signal LOW by default. The is a pin chip. This means that either side of the switch can be used as the input. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.
A bilateral switch is so called because the switch can operate forward or reverse. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.
In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. Each switch has a single input and a single output terminal. The really functions as an analog switch.
The pinout of the chip is shown below. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad datasneet switch chip. The control terminal enables the input to go to output. The has a wide operating voltage of 5VV. So you will see that if you press down the pushbutton with an analog signal or digital signal at the input, that same signal cdd4066 appear at hte output. Each switch also has a control or enable terminal.
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.
