Post as a guest Name. The comparator output is. Then, can you explain more? Email Required, but never shown. In a typical application any one of the three comparators feed an external filter network which in turn feeds the VCO input.
I can’t open the size you posted. Sign up using Email and Password. This output normally is used by tying. In a very old chip – CDB’s datasheeti find this: Features s Low dynamic xatasheet consumption: I will check that it still works.
Input transition time of 74HC Ask Question. HC is featured on www. I think you mean ” badbeetles. Sign up or log in Sign up using Google. I usually thought it’s the value “recommended”. Thanks for your reply. It is saying it datasheeh always recognise 2. This input is a very high impedance CMOS input. The first parameter is giving the lowest voltage that the chip will treat as a HIGH on its input. In general, maximum and minimum values are guaranteed, typical values are not.
Home Questions Tags Users Unanswered. An inhibit pin is provided to disable the VCO and the source follower, providing a method of putting the IC in a low power dattasheet. If it does, then you can ignore it.

II, i thought this 47hc4046 for DC coupled signal. Especially in such an old design, like this part. I didnt design the website. David G In 74HC’s datasheetsection “Recommended operating conditions”, i find this. Phase comparator II is an edge sensitive digital sequential.
And for 74HC, when it gives the AC coupled input sensitivity, it also gives the test condition: Does it have any relation with transition time? This input is a very high impedance CMOS input which also drives the source follower. Or if can recommend another better chip. This phase detector is more susceptible to locking onto harmonics of the input fre- quency than phase comparator 74hc046, but provides better noise rejection.
I don’t think it’s a typo, because there are others like this, such 74hc4406 p. Strange parameters in datasheet datasueet 74HC Ask Question.
