Im using the NL27WZ14 in a test application. I have a question about the DC electrical characteristics of the of the part as described on page 3 of the data sheet.

First off I see that the Min and Max ranges that causes the trigger to switch is dependent upon VCC. The board I am testing has 5V VCC but there is no 5 V VCC in the data sheet only 4.5V VCC and 5.5V VCC so what min and max voltage threshold should I use? The one for 4.5V VCC or 5.5V VCC?
Second. I went ahead and decided to follow the 4.5V VCC voltage thresholds. -40C to 85C.
Vt-Min = 1V
Vt-Max = 2V
So this means that I will switch off(negative) between 1V and 2V?
Vt+Min = 1.9V
Vt+Max = 3.1V
So this means that I will switch on(positive) between 1.9V and 3.1V?
I see that my Vt-Max (2V) is larger than my Vt+Min (1.9V). Can you do that? Can you say that I want to turn on (go high) at 1.9V but then turn off (go low) at 2.0V? I thought there has to be some voltage delta between the Vt+min and Vt-max that keeps the NL27WZ14 in a none switching state?
So what is VH = 0.6 Min and 1.5 Max?
Does VH mean the voltage range will not switch on or off between 0.6V and 1.5V?
