COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; and the functional operation of
the device (at these or any other conditions above
those indicated in the operational sections of this speci-
fication) is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

Notes: (1)VIL min. and VIH max. are for reference only and are not tested.
(2)This parameter is periodically sampled and not 100% tested.
(3)tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated. These parameters are
periodically sampled and not 100% tested.
