I’m now working on a design, like this: Any voltage lower than 0.

74HC4046 Datasheet

It means most chips will ‘typically’ recognise 1. This device contains a low power linear voltage controlled oscillator VCOa source follower, and three phase comparators. This output normally is used by tying a resistor from pin datashet to ground, and provides a means of looking at the VCO input without loading down modifying the characteristics of the PLL filter.

For AC coupling, if the input signal is sine wave, and the frequency must be greater than 10kHz. This phase detector is.


In datahseet of 74HC, page. Phase comparator II is an edge sensitive digital sequential network.

This phase detector is more susceptible to locking onto harmonics of the input fre- quency than phase comparator I, but provides better noise rejection.

The MM74HC is a low power phase lock loop utilizing. The three phase comparators have a common signal input and a common comparator input. In general if the data-sheet mentions something, you should follow it.

Similarly, the maximum voltage that is guaranteed to be recognized as a LOW is 0. By using our site, you acknowledge that you have read and understand our Daatsheet PolicyPrivacy Policyand our Terms of Service.

Post as a guest Name. And for 74HC, when it gives the AC coupled input sensitivity, it also gives the test condition: In general, maximum and minimum values are guaranteed, typical values are not. Features s Low dynamic power consumption: I thought there are some relation to the word “typical”.


In 74HC’s datasheetsection “Recommended operating conditions”, i find this. Fairchild Semiconductor Electronic Components Datasheet.

Ddatasheet it have any relation with transition time? Thanks for your reply. I want to know, in AC coupling signal, for sine wave, why it limits the frequency?

I know this is a “old” part, can your suggest a newer one suited for me. Home Questions Tags Users Unanswered.

I don’t think it’s a typo, because there are others like this, such as p. Then, can you explain more?
