(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 internal self-heating where T
J
> T
A
.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using
Statistical Quality Control (SQC) methods.
(3) Typical numbers are the most likely parametric norm.
(4) Slew Rate is the average of the rising and falling edges.
