*Full range(MIN to MAX),for the LM393 is 0 to 70 .All characteristics are measured with
zero common-mode input voltage unless otherwise speified.
**The voltage at either input or common-mode should not be go negative by more than 0.3V.The upper
end of the common-mode voltage range is Vcc+-1.5V,but either or both inputs can go to 30V without damage
