It may have been damaged by static electricity. Who We Are Management.

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 Product is in design feasibility stage. Computers and Peripherals Data Center. May 26, Originally posted by Paul Marossy Really?

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 doing.

And you can’t see if it has been damaged by static, either. Marketing proposal for customer feedback. Anyone, help me please, thanks First, to power thewe connect 5V of power to V DDpin 14, and we connect the ground pin, pin 7, to ground.


The most common waveform is a sine wave. May 27, In this circuit, we will show the basic functionality of the chip by passing analog signals through 2 of the switches by digital control.

No commitment taken to produce Proposal: 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. So you will see that if you vatasheet down the pushbutton with an analog signal or digital signal at the input, that same signal will appear at hte output.

The quad bilateral switch chip is a chip that is made up of 4 switches. To the inputs hcc4066 the 2 switches, we feed an analog signal. It can be obtained cheaply at a number of online electronic retailers. For this circuit, we are only going to be using 2 of the 4 switches. Distributor Name Region Stock Min.

As long as it is a CD, hcf066 should work. Media Subscription Media Contacts. Product is in volume production. The datasheet for the can be found at the following link: 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.


According to the datasheets, they are supposed to be the same thing. Menu Products Explore our product portfolio.

When pressed down, the pushbutton makes the signal HIGH. Support Center Video Center. That would be the first type of IC chip that I have ever run across that was quirky like that. The is a quad bilateral switch circuit, meaning that is composed of 4 switches.

They are not as rugged as something like an opamp. No commitment taken to design or produce NRND: Try a different one in its place and see what happens. Paul Marossy Hero Member Posts: Like Paul said – if you use a socket you will eliminate a lot of the problems that could happen replacing an IC like this.
