Note 1:
All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2:
“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.
“Electrical Characteristics”
state DC and AC electrical specifications under particular test conditions
which guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where
no limit is given, however, the typical value is a good indication of device performance.
Note 3:
For operating at case temperatures above 25˚C, the device must be derated based on a 150˚C maximum junction temperature and a thermal resistance
of
θ
JA
= 80˚C/W (junction to ambient).
Note 4:
Human body model, 100pF discharged through a 1.5kΩ resistor.
Note 5:
Machine Model 220pF−240pF discharged through all pins.
Note 6:
The operating junction temperature maximum is 150˚C.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
