In a typical application any one of the three comparators. Those are not typos. 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 dataheet PLL filter.

74HC Datasheet(PDF) – NXP Semiconductors

In a very old chip – CDB’s datasheeti find this:. I’m now working on a design, like this: This input is a very high impedance CMOS input. I want to know, in AC coupling signal, for sine wave, why it limits the frequency? And at kHz sine wave input, the minimum sensitivity is mV max.

Sign up or log in Sign up using Google. And for 74HC, when it gives the AC coupled input sensitivity, it also gives the test condition: Phase comparator II is an edge sensitive digital sequential network.


All of the other values in the specification should be interpreted in the same way. Features s Low dynamic power consumption: This comparator is more susceptible to noise throw.

You’d need more detail to be sure. This device contains a low power linear voltage. HC is featured on www. The three phase comparators have vatasheet common signal input and a common comparator input.

The SIGin input goes to a bufferso presumably that will shape things up nicely for subsequent processing. Email Required, but never shown. The three phase comparators have a. David G Why the typical value may bigger than the max.

This output normally is used by tying.
