Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
Electrical Characteristics
Limits in standard typeface are for T
otherwise specified. V
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its operating conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
Ambient Thermal Resistance), and T
number given in the Absolute Maximum Ratings, whichever is lower.
Note 3: The Human Body Model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 4: Typical numbers are at 25°C and represent the most likely parametric norm.
Note 5: Min. and Max. limits in standard typeface are 100% production tested at 25°C. Min. and Max. limits in boldface are guaranteed through correlation using
Statistical Quality Control (SQC) methods. The limits are used to calculate National's Average Outgoing Quality Level (AOQL).
Note 6: Factory-trimmed reset thresholds are available in 50 mV increments from 2.4V to 5.0V. Contact your National Semiconductor representative.
