The most common waveform is a sine wave.

The Parker Guitars Forum. Media Subscription Media Contacts. Communications Equipment, Computers and Peripherals. This means that either side of the switch can be used as the input. Limited Engineering samples available Preview: 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 other possibility is that the PCB had been damaged with the replacement of that part or there is a cold solder joint.

I hadn’t thought of that May 27, Dahasheet pinouts, same description of what it does, etc. Each switch has an input, output, and control terminal.

V DD and ground, pins 14 and 7, are the power pins. The is a pin chip. The is a quad bilateral switch circuit, meaning that is composed of 4 switches. 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.

I guess they can be finicky things, eh? It doesn’t matter who made it, or if there is a different “code” on it. And you can’t see if it has been damaged by static, either. My vote is for a bad solder joint, a solder bridge, or the PCB being damaged from the process of removing the old chip.


Each switch also has a control or enable terminal.

Product is in volume production. In this circuit, we will show how to connect a bilateral switch chip to inputs and outputs using the quad bilateral switch chip. Product is in volume production only to support customers ongoing production. General terms and conditions. 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. I suppose the circuit it is going in matters, too.

The quad bilateral switch chip is a chip that is made up of 4 switches.

A CD is a CD When dataasheet down, the pushbutton makes the signal HIGH. May 26, ST Code of Conduct Blog. In order for signals to pass through from the input side to the output side, the control or enable terminal must be HIGH. 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.

Try a different one in its place and see what happens.

It’s very easy to damage some PCBs and I’ve had cold solder joints that look like they should be great. The hcff4066 a wide operating voltage of 5VV.


Like Paul said – if you use a socket you will eliminate a lot of the problems that could happen replacing an IC like this. To the inputs of the 2 switches, we feed an analog signal. So you will see that if you press down the pushbutton hcf4066 an analog signal or digital signal at the input, that same signal will appear at hte output.


Marketing proposal for customer feedback. When unpressed, the pushbutton has the signal LOW by default. Computers and Peripherals Data Center. 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.


For me it was only a pain in battery powered circuits since voltage varies a little and current is a concern – I had to put some actual thought into what I was adtasheet. So current can flow in one direction and the other direction, depending on which side is the input.

One place it can be obtained is at Taydaelectronics at the following link: Product is in design stage Target:
