Electrical Characteristics (continued)
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 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. Unless otherwise
specified, V
