Electrical Characteristics VIN = 5V unless otherwise indicated under the Conditions column. Limits in standard
type are for T
J = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Minimum
and Maximum limits are guaranteed 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.
