(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 ensured specification of parametric performance is indicated in the electrical
tables under conditions of internal self-heating where T
J
> T
A
. 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 or statistical analysis.
(3) Typical Values represent the most likely parametric norm.
(4) Slew rate is the slowest of the rising and falling slew rates.
(5) Average drift is determined by dividing the change in parameter at temperature extremes into the total temperature change.
