IC CD4066 DATASHEET PDF
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 most common waveform is a datasheef wave. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. The really functions as an analog 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.
The is a pin chip. 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. As the quad term implies, the is composed up of 4 switches.
For this circuit, we datashet only going to be using 2 of the 4 switches.
How to Build a Quad Bilateral Switch Circuit In this circuit, we will show how satasheet connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.
One place it can be obtained is at Taydaelectronics at the following link: In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. The datasheet for the can be found at the following link: To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. Datashete can be obtained cheaply at a number of online electronic retailers.
Each switch also has a control or enable terminal. V DD and ground, pins 14 and 7, are the power pins. In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control. The has a wide operating voltage of 5VV.
How to Build a Quad Bilateral Switch Circuit
Without the control or enable switch, there can be no output. The pinout of the chip is shown below. To the inputs of the 2 switches, we feed an analog signal. The switches are labeled from 1 to 4.
If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. Each switch has a single input and a single output terminal. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.
A bilateral switch is so called because the switch can operate forward or reverse. Applying these principles, you can easily see how to use all 4 switches if wanted.
You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. A bilateral switch acts as a datasheet pole, single throw switch. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.
How to Build a 4066 Quad Bilateral Switch Circuit
When unpressed, the pushbutton has the signal LOW by default. This cx4066 that either side of the switch can be used as the input. The is an IC composed of switches which are designed to switch analog signals via digital control.
The cd066 bilateral switch chip is a chip that is made up of 4 switches. If the pushbuttons are not pressed down, then no signal will appear at the outputs.
When pressed down, the pushbutton makes the signal HIGH. This enables the signal at the input to go to the output. Each switch has an input, output, and control terminal. This establishes sufficient power to the chip. 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 datzsheet or enable terminal.
With the control switch HIGH, then the switch closes and there can cd40666 an output. So current can flow in one direction and the other direction, depending on which side is the input. The control terminal enables the input to go to output.
