Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. For ensured
specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed.
Some performance characteristics may degrade when the device is not operated under the listed test conditions.
(2)
All voltages are measured with respect to the ground pin, unless otherwise specified.
(3)
Typical specifications are specified at +25°C and represent the most likely parametric norm.
(4)
Tested limits are specified to AOQL (Average Outgoing Quality Level).
