Absolute Ratings and Operating Conditions
Absolute Ratings and Operating Conditions
Stresses greater than those listed may cause permanent damage to the device. This is a
stress rating only, and functional operation of the device at these or any other condi-
tions outside those indicated in the operational sections of this specification is not im-
plied. Exposure to absolute maximum rating conditions for extended periods may ad-
versely affect reliability.

1. During signal transitions, minimum voltage may undershoot to −2V for periods less than
20ns.
Notes:
2. During signal transitions, maximum voltage may overshoot to VCC + 2V for periods less
than 20ns.
3. VPPH must not remain at 9V for more than 80 hours cumulative.
