Electrical Characteristics
Limits in standard type are for T
J
= 25°C only; limits in boldface type apply over the junction temperature (T
J
) range of -40°C
to 125°C. Minimum and Maximum limits are specified through test, design, or statistical correlation. Typical values represent
the most likely parametric norm at T
J
= 25°C, and are provided for reference purposes only. V
IN
= 5V, unless otherwise
indicated under the Conditions column.
