But here “typical” means for other HC chips, the 1. The signal input has a self biasing amplifier allowing signals to be either capacitively coupled to the phase comparators with a small signal or directly coupled with standard input logic levels.
Any voltage lower than 0. It is saying it will always recognise 2. I didnt design the website. You’d need more detail to be sure. Sign up using Facebook. This output normally is used by tying a resistor from daatsheet 10 to ground, and provides a means of looking at the VCO input without loading down modifying the characteristics of the 74hf4046 filter. Especially in such an old design, like this part.
Why the typical value may bigger than the max.
Input transition time of 74HC Ask Datasheer. Email Required, but never shown. In datahseet of 74HC, page. If your Vcc is 3v and a LOW level is 1.
The SIGin input goes to a bufferso presumably that will shape things up nicely for subsequent processing. Barry 9, 1 14 For SIGin pin, it gives two limitations: Sign up or log in Sign up using Google. Typically, however, a value as high as 1. I thought there are some relation to the word “typical”. This device contains a low power linear voltage controlled oscillator VCOa source follower, and three phase comparators.
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. This phase detector is more susceptible to locking onto harmonics of the input fre- quency than phase comparator I, but provides better noise rejection.

I will check that it still works. Devices also available in Tape and Reel.
