Electrical Characteristics (continued)
Specifications in standard type are for T
J
= 25°C only, and limits in boldface type apply over the junction temperature (T
J
)
range of -40°C to +125°C. Unless otherwise stated, Vin=12V. Minimum and Maximum limits are ensured 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.
