Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is
intended to be functional, but device parameter specifications may not be guaranteed. For guaranteed specifications and test conditions, see “Electrical
Characteristics”.
Note 2: As long as TA ≤ +85C, all electrical characteristics hold true and the junction temperature should remain below +125C.
Note 3: The Human Body Model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The Machine Model is a 200 pF capacitor discharged
directly into each pin.
Note 4: Typical numbers are at 25C and represent the most likely norm.
