10. Electrical Specifications
10.1 Absolute Maximum Ratings
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 5 .
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 .
2. Minimum DC input voltage on pin V
PP
is -0.5V. During voltage transitions, V
PP
may overshoot V
SS
to –2.0 V for periods of up to 20 ns. See Figure 5 . Maximum DC
voltage on pin V
PP
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.
