For this circuit, we are only going to be using 2 of the 4 switches.
Limited Engineering samples available Preview: When pressed down, the pushbutton makes the signal HIGH. I think the TI parts always worked, but that was after trying others that seemed to work OK in other circuits when I checked a few. The is an IC composed of switches which are designed to switch analog signals via digital control.
No commitment taken to design or produce NRND: If I use the mono jack all signal is Normal. Media Subscription Media Contacts. Product is in design feasibility stage.
Not Recommended for New Design. Product is in volume production Evaluation: In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH.
In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. Please contact our sales support for information on specific devices.
Communications Equipment, Computers and Peripherals.
Applying these principles, you can easily see how to use all 4 switches if wanted. No commitment taken to produce Proposal: Thanks all, I will upload the picture soon. 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. Each switch has an input, output, datasheef control terminal.
This establishes sufficient power to the chip. The quad bilateral switch chip is a chip that is made up of 4 switches.
If the switching signal is marginal, or not filtered well, then you can have problems with some manufacturer’s CD parts and some models of those parts in some cases. Support Center Complete list and gateway to support services and resource pools.
Try a different one in its place and see what happens.
General terms and conditions. The has a wide operating voltage of 5VV. The most common waveform is a sine wave. The is a quad bilateral switch circuit, meaning that is composed of 4 switches.
The pinout of the chip is shown below.
May 27, Thanks for ur info Paul, have any idea, advice for my problem guys? ST Code of Conduct Blog. May 28, This is image of IC this is the pictures of both Ic What this hfc4066 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.
As the quad term implies, the is composed up of 4 switches. Been there, done that.
