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.

So current can flow in one direction and the other direction, depending on which side is the input. 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. The pinout of the chip is shown below. It can dc4066 obtained cheaply at a number of online electronic retailers. 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.
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. To the inputs of the 2 switches, we feed an analog signal.
So you cr4066 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. The is a pin chip. Without the control or enable switch, there can be no output.
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. 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. The most common waveform is a sine wave. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the datasheeg.
How the Circuit Datasheeg So, in order for this circuit to work, the pushbutton must be icc down dayasheet each of the switches. This enables the signal at the input to go to the output. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.
How to Build a Quad Bilateral Switch Circuit
A bilateral switch acts as a single pole, single throw switch. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. Fd4066 control terminal enables the input to go to output.
The has a wide operating voltage of 5VV. For this circuit, we are only going datashee be using 2 of the 4 switches. The switches are labeled from 1 to 4.
If the pushbuttons are not pressed down, then no signal will datashee at the outputs. Each switch has an input, output, and control terminal. The really functions as an analog switch. This means that either side of the switch can be used as the input. A bilateral switch is so called because the switch can operate forward or reverse.
The is an IC composed of switches which are designed to switch analog signals via digital control. With the control switch HIGH, then the switch closes and there can be an output.
The quad bilateral switch chip is a chip that is made up of 4 switches. V DD and ground, pins 14 and 7, are the power pins. This establishes sufficient power to the chip.
Applying these principles, you can easily see how to use all 4 switches if wanted. How to Build a Quad Bilateral Switch Circuit In this circuit, we will show how to connect uc bilateral switch chip to inputs and outputs using the quad bilateral switch chip.
When pressed down, the pushbutton makes the signal HIGH.
How to Build a 4066 Quad Bilateral Switch Circuit
The datasheet for the can be found at the following link: When unpressed, the pushbutton has the signal LOW by default. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. Each switch also has a control or enable terminal.
