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.

In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. The really functions as an analog switch. The dataaheet an IC composed of switches which are designed to switch analog dataxheet via digital control. What this means is we feed an analog signal into the input of the switch and it reaches datashdet output only if a HIGH digital signal is fed into the 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. A bilateral switch is so called because the switch can operate forward or reverse. This means that either side of the switch can be used as the input.

So current can flow in one direction and the other direction, depending on which side is the input. A bilateral switch acts as a single pole, single throw switch. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. Each switch has a single input and a single output cd40666. Each switch also has a control or enable terminal. In order for signals to pass cd406 from the input side to the output side, the control or enable terminal must be HIGH.

You can view the control terminal as the signal which closes the switch so that the input signal can dataasheet over to the output. Without the control or enable switch, there can iic no output.

With the control switch HIGH, then the switch closes and there can be an output. 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 quad bilateral switch chip is a chip that is made up of 4 switches. It can be obtained cheaply at a number of online electronic retailers. One place it can be obtained is at Taydaelectronics at the following link: The is a pin chip.

How to Build a Quad Bilateral Switch Circuit

The datasheet for the can be found at the following link: The has a wide operating voltage of 5VV. The pinout of the chip is shown below.

As the quad term implies, the is composed up of 4 switches. The switches are labeled from 1 to 4.

Practical Electronics/IC/4066

Each switch has an input, output, and control terminal. The control terminal enables the input to go to output.

datasheet V DD and ground, pins 14 and 7, are the power pins. First, to lc thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. This establishes sufficient power to the chip.

For this circuit, we are only going to be using 2 of the 4 switches. Applying datasheeet principles, you can easily see how to use all 4 switches if wanted. To the inputs of the 2 switches, we feed an analog signal. The most common waveform is a sine wave. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit.

When unpressed, the pushbutton has the signal LOW by default. When pressed down, the pushbutton makes the signal HIGH.

How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. This enables the signal at the input to go to the output. If the pushbuttons are not pressed down, then ci signal will appear at the outputs.

So you will see that if you press down the datxsheet with an analog signal daatasheet digital signal at the input, that same signal will appear at hte output.

If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. 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.
