Stresses in excess of those listed above may result in permanent damage. These
are stress ratings only, and operation at these levels is not implied. Frequent or
extended exposure to absolute maximum conditions may effect device reliability.
DC CHARACTERISTICS
(1) Under steady state (non-transient conditions, IOL must be limited externally as follows:
(2) If IOL exceeds the test conditions, VOL may exceed the related specifications.
(3) Pins are not guaranteed to sink current greater than the listed test conditions.
