Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and test conditions see the Electrical
Characteristics Table.
Note 2: See Application Information when input supply voltage is less than the VCC voltage.
Note 3: These pins are output pins. As such they are not specified to have an external voltage applied.
Note 4: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 5: Minimum VIN operating voltage is defined with VCC supplied by the internal HV startup regulator and no external load on VCC. When VCC is supplied
by an external source, minimum VIN operating voltage is 4.5V.
Note 6: Operating current does not include the current into the R
Note 7: High and low reference are 80% and 20% of the pulse amplitude respectively.
