(1)

Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary

over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped

production material.

(2)

All limits are specified by testing or statistical analysis.

(3)

CL includes the probe and test jig capacitance.
