(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical

tables under conditions of internal self-heating where TJ > TA. Absolute Maximum Ratings indicate junction temperature limits beyond

which the device may be permanently degraded, either mechanically or electrically.

(2)

All limits are specified by testing, statistical analysis or design.

(3)

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.
