ELECTRICAL CHARACTERISTICS (continued)
Specifications in standard type face are for T
J
= 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 specified through test, design, or statistical
correlation. Typical values represent the most likely parametric norm at T
J
= +25ºC, and are provided for reference purposes
only. Unless otherwise stated the following conditions apply: V
EE
= -12.0V and V
