Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
DC Electrical Characteristics
Limits in standard typeface are for T
less 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 rated operating conditions.
Note 2: The maximum allowable power dissipation is a function of the Maximum Junction Temperature (T
the Ambient Temperature (T
at any temperature is P
thermal shutdown.
Note 3: The Human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 4: Thermal Shutdown will protect the device from permanent damage.
