= 25°C and those with boldface type apply over the full Operating Temperature
Range ( T
J
= −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
stated the following condition applies: V
