Note1 : Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note2 : ESD Test Condition is IEC 61000-4-2 Standard which is 330 in series with 150pF
Note3 : Supply Voltage indicates conditions for which the device is intended to be functional, but specific performance is not guaranteed
for guaranteed specifications and the conditions, see the Electrical Characteristics.
