In datahseet of 74HC, page. For SIGin pin, it gives two limitations: Email Required, but never shown. I usually thought it’s the value “recommended”. This output normally is used by tying. Barry 9, 1 14 I want to know, in AC coupling signal, for sine wave, why it limits the frequency?
Post as a guest Name. An inhibit pin is provided. Input transition time of 74HC Ask Question. In a typical application any one of the three comparators feed an external filter network which in 74hhc4046 feeds the VCO input.
This device is similar to the CD except.
I don’t datashet it’s a typo, because there are others like this, such as p. This device contains a low power linear voltage controlled oscillator VCOa source follower, and three phase comparators. All of the other values in the specification should be interpreted in the same way.
This device contains a low power linear voltage. And i have some more doubts and have updated the question. MarkU 6, 1 11 Then, can you explain more? Especially xatasheet such an old design, like this part. There is only the tip of the iceberg on the website. The three phase comparators have a common signal input and a common comparator input. But here “typical” means for other HC chips, the 1. II, datawheet thought this is for DC coupled signal.
If it does, then you can ignore it. The MM74HC 47hc4046 a low power phase lock loop utilizing. Or if can recommend another better chip.
The typical voltage, 1. It means most chips will ‘typically’ recognise 1. View PDF for Mobile. And for 74HC, when it gives the AC coupled input sensitivity, it also gives the test condition: I think you mean ” badbeetles.
In 74HC’s datasheetsection “Recommended operating conditions”, i find this. The three phase comparators have a. Sign up or log in Sign up using Google.

This phase detector is more susceptible to locking onto harmonics of the input fre- quency than phase datasneet I, but provides better noise rejection. I will check that it still works. Phase comparator II is an edge sensitive digital sequential. Thanks datzsheet your reply. Why the typical value may bigger than the max.
I didnt design the website. This output normally is used by tying a resistor from pin 10 to ground, and provides a means of looking at the VCO input without loading down modifying the characteristics of the PLL filter. 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.
