It can be used to provide the phase comparator functions and is similar to the first comparator in performance. I want to know, in AC coupling signal, for sine wave, why it limits the frequency? This device is similar to the CD except that the Zener diode of the metal gate CMOS device has been replaced with a third phase comparator. An inhibit pin is provided.

I think you mean ” badbeetles. Any voltage lower than 0.

Sign up datasheey log in Sign up using Google. This input is a very high impedance CMOS input which also drives the source follower. Or if can recommend another better chip. Then, can you explain more?

74HC4046 Datasheet

If your Vcc is 3v and a LOW level is 1. HC is featured on www.

The first parameter is giving the lowest voltage that the chip will treat as a HIGH on its input. Sign up using Facebook. The MM74HC is datasheet low power phase lock loop utilizing. This input is a very high impedance CMOS input. This output normally is used by tying.

Home Questions Tags Users Unanswered. 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.

This phase detector is.

Strange parameters in datasheet of 74HC – Electrical Engineering Stack Exchange

This comparator is more susceptible to noise throw. Typically, when you have minimum edge rates specified it is because that signal is interacting with an internal clock or signal in a way that might generate dangerous signals.

MarkU 6, 1 11 Sign up using Email and Password. Strange parameters in datasheet of 74HC Ask Question. And for 74HC, when it gives the AC coupled input sensitivity, it also gives the test condition: Any voltage higher than 2.


In 74HC’s datasheeetsection “Recommended operating conditions”, i find this. Barry 9, 1 14 Fairchild Semiconductor Electronic Components Datasheet. This comparator is more susceptible to noise throw- ing the loop out of lock, but is less likely to lock onto har- monics than the other two comparators.

It means most chips will ‘typically’ recognise 1. Input transition time of 74HC Ask Question. There is only the tip of the iceberg on the website.

74HC Datasheet pdf – CMOS Phase Lock Loop – Fairchild Semiconductor

In a typical datasjeet any one of the three datasheet feed an external filter network which in turn feeds the VCO input. Sign up or log in Sign up using Google. 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. Features s Low dynamic power consumption: Why the typical value may bigger than the max.

II, i thought this is for DC coupled signal. I can’t open the size you posted.
