Notes:
1.
Minimum DC voltage on input or I/Os is –0.5 V During
voltage transitions, input at I/Os may undershoot V
SS
to
–2.0 V for periods of up to 20 ns during voltage transitions
inputs might overshooot to V
CC
+0.5 V for periods up to
20 ns. See Figure 5. Maximum DC voltage on output and
I/Os is V
CC
+ 0.5 V During voltage transitions outputs
may overshoot to V

+ 2.0 V for periods up to 20 ns. See
Figure 6.

voltage transitions, V
PP
may overshoot V
SS
to –2.0 V for
periods of up to 20 ns. See Figure 5. Maximum DC input
voltage on V
PP
is +12.5 V which may overshoot to +13.5
V for periods up to 20 ns.
3. No more than one output may be shorted to ground at a
time. Duration of the short circuit should not be greater
than one second.
4. 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 de-
vice at these or any other conditions above those ndicated
in the operational sections of this data sheet is not implied.
Exposure of the device to absolute maximum rating condi-
tions for extended periods may affect device reliability.
