Absolute Maximum Ratings(Note 1)

Recommended Operating

Conditions (Note 3)

Note 1: The Absolute Maximum Ratings are those values beyond which

the safety of the device cannot be guaranteed. The device should not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the Absolute Maximum Rat-

ings. The “Recommended Operating Conditions” table will define the condi-

tions for actual device operation.

Note 2: IO Absolute Maximum Rating must be observed.

Note 3: Floating or unused control inputs must be held HIGH or LOW.

DC Electrical Characteristics

(2.7V

< V

CC ≤ 3.6V)

Note 4: An external driver must source at least the specified current to switch from LOW-to-HIGH.

Note 5: An external driver must sink at least the specified current to switch from HIGH-to-LOW.
