Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.

Note 2: The Human Body Model (HBM) is 1.5 k

Ω in series with 100 pF. The Machine Model is 0Ω in series with 200 pF.

Note 3: Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of

Note 4: All limits are guaranteed by design or statistical analysis.

Note 5: Typical values represent the most likely parametric norm.

Note 7: The Supply Current depends on the applied Clock Frequency and the load on the DATA output.
