Electrical Characteristics
Limits in standard type are for T J = 25°C only; limits in boldface type apply over the junction temperature range of (T J = -
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.
