Applying these principles, you can easily see datashet to use all 4 switches if wanted. Product is in design stage Target: Rad-hard, high voltage, CMOS logic series. You can view the control terminal as the signal which closes the switch so that the input signal can cross over to the output. This is image of IC this is the pictures of both Ic Without the control or enable switch, there can be no output. 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 – it’s not crazy to try another brand.
To the inputs of the 2 switches, we feed an analog datazheet. Product is in volume production. One place it can be obtained is at Taydaelectronics at the ucf4066 link: No availability reported, please contact our Sales office.

I have a problem with my Midifly series. Paul Marossy Hero Member Posts: This means that either side of the switch can be used as the input. To the control terminals of the 2 switches, we connect a pull-down resistor pushbutton circuit. It’s very easy to damage some PCBs and I’ve had cold solder joints that look like they should be great.
The Parker Guitars Forum. Please contact our sales support for information on catasheet devices. I hadn’t thought of that The pinout of the chip is shown below.
Computers and Peripherals Data Center. 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.
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. CMOS devices are especially sensitive to static electricity. No commitment taken to produce Proposal: The control terminal enables the input to go to output.
I think the Datasgeet parts always worked, but that was after trying others that seemed to work OK in other circuits when I checked a few.
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. It can be obtained cheaply at a number of online electronic retailers.
I don’t know if a replacement board is available, you’d have to talk to Parker customer service about that. CMOS devices can be damaged by static electricity simply by touching them out of circuit with your bare hands, and it gets worse from there. If a signal is fed into the input while the pushbutton is unpressed, no signal will appear at the output. The has a wide operating voltage of 5VV. Been there, done that. This establishes sufficient power to the chip.

If so, I wonder if that might be a factor. Originally posted by Paul Marossy Really?
I guess they can be finicky things, eh? May 26, They are not as rugged as something like an opamp. Support Center Complete list and gateway to support services and resource pools.

Each switch has a single input and a single output terminal. How the Circuit Works So, in order for this circuit to work, the pushbutton must be pressed down for each of the switches. May 27, Limited Engineering samples available Preview: Each switch also has a control or enable terminal. The other possibility is that the PCB had been dataasheet with the replacement of that part or there is a cold solder joint.
I wonder what might have happened right before this problem started – things like the wrong polarity on a battery can mess up a lot of things. A bilateral switch acts as a single pole, single throw switch.
