Electrical Characteristics Unless otherwise stated, the following conditions apply: V
IN = 12V. Limits in standard
type are for T
J = 25°C only, limits in bold face type apply over the junction temperature (TJ) 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.
