Absolute Maximum Ratings
(Note 1)
Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.

is measured with all outputs OPEN, SERIAL inputs grounded, the CLOCK input at 2.4V, and a momentary ground, then 4.5V, applied to the
CLEAR input.
