Media Subscription Media Contacts. In this circuit, we will show the basic functionality of the datashewt by passing analog signals through 2 of the switches by digital control. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip.

How to Build a 4066 Quad Bilateral Switch Circuit

The has a wide operating voltage of 5VV. My vote is for a bad solder joint, a solder bridge, or the PCB being damaged from the process of removing the old chip.

If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. Communications Equipment, Computers and Peripherals. Product is in volume production Evaluation: Same pinouts, same description of what it does, etc. The quad bilateral switch chip is datzsheet chip that is made up of 4 switches. General terms and conditions.


IoT for Smart Things. Each switch also has a control or enable terminal.

How to Build a Quad Bilateral Switch Circuit

This establishes sufficient power to the dwtasheet. I have a problem with my Midifly series. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches.

First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground. Product is under characterization.

I guess they can be finicky things, eh? I also made an MXR Envelope Filter and found that it’s a significant problem with analog inputs on the control pins – older ‘s worked, only the new TI parts worked, although the new ICs all worked for other things. When unpressed, the pushbutton has the signal LOW by default. One place it can be obtained is at Taydaelectronics at the following link: Anyone, help me please, thanks May 26, That’s not to say that the TI ICs will work here or that other issues might not exist, but if one brand if does not work and you have eliminated everything else – ddatasheet not crazy to try another brand.


Marketing proposal for customer feedback. I wish it wasn’t, but that’s not been my experience – even in slow routing logic switch circuits.

Product is in design stage Target: Product is in volume production. 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 datadheet the switch.

As long as it is a CD, it should work. Paul Marossy Hero Member Posts: 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.

V DD and ground, pins 14 and 7, are the power pins. With the control switch HIGH, then the switch closes and there can be an output. Support Center Complete list and gateway to support services and resource pools.
