Does it have any relation with transition time?

I can’t open the size you posted. Sign up or log in Sign up using Google. If it does, then you can ignore it. I know this is a “old” part, can your suggest a newer one suited for me. This device contains a low power linear voltage controlled oscillator VCOa source follower, and three phase comparators.

Barry 9, 1 14 I didnt design the website.

This phase detector 74hd4046 more susceptible to locking onto harmonics of the input fre- quency than phase comparator I, but provides better noise rejection. Sign up using Email and Password.

Post as a guest Name. David G I want to know, in AC coupling signal, for sine wave, why it limits the frequency? The three phase comparators have a common signal input and datasheeh common comparator input. Sign up using Email and Password. Similarly, the maximum voltage that is guaranteed to be recognized as a LOW is 0.

You’d need more detail to be sure. In datahseet of 74HC, page. MarkU 6, 1 11 This device is similar to the CD except. It means most chips will ‘typically’ recognise 1. If your Vcc is 3v and a LOW level is 1. In 74HC’s datasheetsection “Recommended operating conditions”, i find this. I will check that it still works. I usually thought it’s the value “recommended”. The SIGin input goes to a bufferso presumably that will shape things up nicely for subsequent processing.

In a very old chip – CDB’s datasheeti find this:. 74hc406

This comparator is more susceptible to noise throw. Phase comparator II is an edge sensitive digital sequential.

Why the typical value may bigger than the max. An inhibit pin is provided to disable the VCO and the source follower, providing a method of putting the IC in a low power state. The first parameter is giving the lowest voltage that the chip will treat as a HIGH dtasheet its input.

Two signal outputs are provided, a comparator. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.
