Dear Friend
I would like to understand more about EN input of the module. Is it logic input with two thresholds far away enough (logic high threshold and logic low threshold) or a single threshold with a narrow range?
From the datasheet, it said: VIH (high-level input voltage) Min 0.9, Typ: 0.65. VIL (low-level input voltage) Max: 0.3, Typ: 0.45. which is a bit confusing.
if just look at the data value, it seems a single threshold with a narrow range of 0.45-0.65. but how to understand Min 0.9 and Max 0.3 values? based on common sense, the normal distribution should be Max 0.9 and Min 0.3...
Could anyone explain it to me?
Thank you
Tony
