(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 T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical tables under
conditions of the internal self heating where T
J
> T
A
.
(2) Typical values represent the most likely parametric norm.
(3) All limits are guaranteed by testing or statistical analysis.
