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 really functions as an analog switch. A bilateral cv4066 is so called because the switch can operate forward or reverse. The is a pin chip. This enables the signal at the input to go to the output. One place it can be obtained is at Taydaelectronics at the following link: If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output.
When pressed down, the pushbutton makes the signal HIGH. Without the control or enable switch, there can be no output.
For this circuit, we are only going to be using 2 of the 4 switches. So by a HIGH digital signal fed lc the control terminal, we can dafasheet 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.
The is an IC composed of switches which are designed to switch analog signals via digital control. Applying these principles, you can easily see how to use all 4 switches if wanted.
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. 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.
Each switch has an input, output, and control terminal. 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. The datasheet for the can be found at the following link: The quad bilateral switch chip is a chip that is made up of 4 switches.
The has a wide operating voltage of 5VV. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.
How to Build a 4066 Quad Bilateral Switch Circuit
This establishes sufficient power to the chip. The pinout of the chip is shown below. With the control switch HIGH, then the switch closes and icc can be an output. The control terminal enables the input to go to output.
V DD and ground, pins 14 and 7, are the power pins. In order for signals to pass through from the input 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. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.
As the quad term implies, the is composed up of 4 switches. Each switch also has a control or enable terminal. How the Circuit Works Dataxheet, in datashest for this circuit to work, the pushbutton must i pressed down for each of the switches. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. When unpressed, the pushbutton has the signal LOW by default.
How to Build a Quad Bilateral Switch Circuit
The most common waveform is a sine wave. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.
Each switch has a single input and a single output terminal. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. So you will see that if you press down daatsheet pushbutton with an analog signal or digital signal at the input, that same signal will appear at hte output. To the inputs of the 2 switches, we feed an analog signal.
It can be obtained cheaply at a number of online electronic retailers. The switches are labeled from 1 to 4.
