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 control terminal enables the input to go to output.

As the quad term implies, the is composed up of 4 switches. Each switch has an input, output, and control terminal. Each switch has a single input and a single output terminal.

Each switch also has a control or enable terminal. Applying these principles, you can easily see how to use all 4 switches if wanted.

First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. It can be obtained cheaply at a number of online electronic retailers.

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 datahseet quad bilateral switch chip. So you will see that if you press down the pushbutton with an analog dd4066 or 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.

When pressed down, the pushbutton makes the signal HIGH. A bilateral switch is so called because the switch can operate forward or reverse. 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. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. The quad bilateral switch chip is a chip that is made up of 4 switches. To the inputs of the 2 switches, we feed an analog signal. The switches are labeled from 1 to 4. A bilateral switch acts as a single pole, single throw switch.

The has a wide operating voltage of 5VV.

You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. The most common waveform is a sine wave. What this means is we feed an analog signal into the input jc the switch and it reaches the output only if a HIGH digital signal is fed into the control or enable terminal.

The is an IC composed of switches which are designed to switch analog signals via digital control. The pinout of the chip is shown below. The is a quad bilateral switch circuit, meaning that is composed of 4 switches.

cd406 This enables the signal at the input to go to the output. Without the control or enable switch, there can be cd40666 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.

The is a pin chip. This means that either side of the switch can be used as the input. The really functions as an analog switch.

V DD and ground, pins 14 and 7, are the power pins. One place it can be obtained is at Taydaelectronics at the following link: With the control switch HIGH, then the datashest closes and there can be an output. When unpressed, the pushbutton has the signal LOW by default. This establishes sufficient power to the chip.

To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. The datasheet for the can be found at the following link: So current can flow in one direction and the other direction, depending on which side is the input. For this circuit, we are only going to be using 2 of the 4 switches.

In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH.
