Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which 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:
These pins must not exceed VIN.
Note 3:
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 4:
All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production at T
A = 25°C. All hot and cold limits
are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 5:
Typical specifications represent the most likely parametric normal at 25°C operation.
Note 6:
Per VCC Regulator
