Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During
voltage transitions, inputs may overshoot V_SS to –2.0 V for
periods of up to 20 ns. Maximum DC voltage on input and
I/O pins is V_CC + 0.5 V. During voltage transitions, input
and I/O pins may overshoot to V_CC + 2.0 V for periods up
to 20ns.
2. Minimum DC input voltage on A9 and V_PP pins is –0.5 V.
During voltage transitions, A9 and V_PP may overshoot
V_SS to –2.0 V for periods of up to 20 ns. Maximum DC
input voltage on A9 and V_PP is +13.0 V which may
overshoot to 14.0 V for periods up to 20 ns.
3. No more than one output shorted to ground at a time.
Duration of the short circuit should not be greater than
one second.
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. This is
a stress rating only; functional operation of the device at
these or any other conditions above those indicated in the op-
erational sections of this specification is not implied. Expo-
sure of the device to absolute maximum rating conditions for
extended periods may affect device reliability.
