Notes:
Operating ranges define those limits between which the
functionality of the device is guaranteed.
1. Minimum DC voltage on input or I/O pins is –0.5 V. During
voltage transitions, inputs may overshoot V to –2.0 V for
SS
periods of up to 20 ns. Maximum DC voltage on input and
I/O pins is V
+ 0.5 V. During voltage transitions, input
CC
and I/O pins may overshoot to V
to 20ns.
+ 2.0V for periods up
CC
2. Minimum DC input voltage on A9 and V pins is –0.5 V.
PP
During voltage transitions, A9 and V
may overshoot
PP
V
to –2.0 V for periods of up to 20 ns. Maximum DC
SS
input voltage on A9 and V
is +13.0 V which may
PP
overshoot to 14.0 V for periods up to 20 ns.
3. No more than one output shorted to ground at a time. Du-
ration 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 opera-
tional sections of this specification is not implied. Exposure of
the device to absolute maximum rating conditions for extended
periods may affect device reliability.
