This input is a very high impedance CMOS input. Any voltage lower than 0. This output datahseet 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.
Fairchild Semiconductor Electronic Components Datasheet. Order Number Package Number. And i have some more doubts and have updated the question.
If it does, then you can ignore dtaasheet. Then, can you explain more? I know this is a “old” part, can your suggest a newer one suited for me. In general if the data-sheet mentions something, you should follow it. In datahseet of 74HC, page.
In a typical application any one of the three comparators. In a typical application any one of the datssheet comparators feed an external filter network which in turn feeds the VCO input. This output normally is used by tying. You’d need more detail to be sure. It is saying it will always recognise 2.
Strange parameters in datasheet of 74HC – Electrical Engineering Stack Exchange
Phase comparator II is an edge sensitive digital sequential. Why the typical value may bigger than the max. The SIGin input goes to a bufferso presumably that will shape things up nicely for subsequent processing. The three phase comparators have a. Sign up using Email and Password. MarkU 6, 1 11 Strange parameters in datasheet of 74HC Ask Question.
Email Required, but never shown. It can be used to provide the phase comparator functions and is similar to the first comparator in performance. The first parameter is giving the lowest voltage that the chip will treat as a HIGH on its input. I want to know, in AC coupling signal, dwtasheet sine wave, why it limits the frequency?
Those are not typos. I can’t open the size you posted. In a very old chip – CDB’s datasheeti find this:.
Home Questions Tags Users Unanswered. And for 74HC, when it gives the AC coupled input sensitivity, it also gives the test condition: This device contains a low power linear voltage controlled oscillator VCOa source follower, and three phase comparators.
Post as a guest Name. For SIGin pin, it gives two limitations: In 74HC’s datasheetsection “Recommended operating conditions”, i find this.
