Quad Bilateral Switch DIP Specifications. The CDBC is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. The really functions as an analog switch. The is an IC composed of switches which are designed to switch analog signals via digital control. What this. Is the equivalent to four independently controllable relays, where one relay switches on the pair X1,Y1?-Is this the purpose of this IC?.

You might be able to control headphone signals and you can certainly control line level audio signals, but definitely not speaker signals. Main purpose is for switching low level analogue signals and, under all but the very cd066 power applications, it cannot switch speaker signals apart from the fact that speaker signals are AC as mentioned and this is a problem.

If you are not happy with your purchase just email us and we will give you full refund. For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab. This will makes your pump on and off according to iic in your tank.

When pressed down, cc4066 pushbutton makes the signal HIGH. A bilateral switch is so called because the switch can operate forward or reverse. Its about the CD IC as mentioned here https: Sign icc for newsletter. If the pushbuttons are not pressed down, then no signal will appear at the outputs. 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 datasheet for the can be found at the following link: Add to watch list.


This item will be shipped through the Global Shipping Program and includes international tracking. What is ccd4066 level indicator: This amount is subject to change until you make payment. CD can be used for audio, but the limitations explained by Andy below make it a bit difficult to work with.

How to Build a 4066 Quad Bilateral Switch Circuit

Special financing available Select PayPal Credit at checkout to have the option to pay over time. Watch list is full. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. Using the relay analogy- considering one pair x1,y1-when there is no signal to turn on the transmission gate-does this mean the resistance is zero between x1,y1?

To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. Sign up or log in Sign up using Google.

Is the equivalent to four independently controllable relays, where one relay switches on the pair X1,Y1? This establishes sufficient power to the chip. Have one to sell? Can it control 4 audio speakers with a CPU? Anonymous March 3, at 1: These are not four relays but transmission gates.

Also visit my homepage 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. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. For details about the switching capabilities have a look at the datasheet.

Any signals are basically constrained to be within the power rails ccd4066, if your power rails are 0 V and 5 volts then signals have to wholly be constrained within these limits with zero exceptions.
