Electrical Characteristics
Unless otherwise specified under the Conditions column, V
IN
= 5V. 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, and are provided for
reference purposes only.
