Notes:
1.
Minimum DC voltage on input or I/Os is –0.5 V. During voltage transitions, inputs or
I/Os may undershoot V
SS
to –2.0 V for periods of up to 20 ns. See
Figure 14.1
.
Maximum DC voltage on input or I/Os is V
CC
+ 0.5 V. During voltage transitions
outputs may overshoot to V
CC
+ 2.0 V for periods up to 20 ns. See
Figure 14.2
.
2.
Minimum DC input voltage on pin ACC is -0.5V. During voltage transitions, ACC may
overshoot V
SS
to –2.0 V for periods of up to 20 ns. See
Figure 14.1
. Maximum DC
voltage on pin ACC is + 9.5 V, which may overshoot to 10.5 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 device at
these or any other conditions above those indicated in the operational sections of this
data sheet is not implied. Exposure of the device to absolute maximum rating conditions
for extended periods may affect device reliability.
