Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
Electrical Characteristics
T
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: Thermal resistance of Z package is 60˚C/W θ
maximum junction temperature shall not exceed 125˚C on electrical parameters.
Note 3: To ensure constant junction temperature, low duty cycle pulse testing is used.
