Data Sheet
9. Electrical Specifications
9.1 Absolute Maximum Ratings
Notes:
1. Minimum DC voltage on input or I/O pins is -0.5V. During voltage transitions, input or I/O pins may undershoot V
SS
to -2.0V for periods of
up to 20 ns. See Figure 9.3 on page 73. Maximum DC voltage on input or I/O pins is V
CC
+0.5V. During voltage transitions, input or I/O
pins may overshoot to V
CC
+2.0V for periods up to 20 ns. See Figure 9.4 on page 73
2. 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.
3. 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.
9.2 Latchup Characteristics
This product complies with JEDEC standard JESD78C latchup testing requirements.
9.3 Operating Ranges

Operating ranges define those limits between which the functionality of the device is guaranteed.
9.3.3 Power-Up and Power-Down
During power-up or power-down V
CC
must always be greater than or equal to V
IO
(V
CC
 V
IO
).
The device ignores all inputs until a time delay of t
VCS
has elapsed after the moment that V
CC
and V
IO
both
rise above, and stay above, the minimum V
CC
and V
IO
thresholds. During t
VCS
the device is performing power
on reset operations.
During power-down or voltage drops below V
CC
Lockout maximum (V
LKO
), the V
CC
and V
IO
voltages must
drop below V
CC
Reset (V
RST
) minimum for a period of t
PD
for the part to initialize correctly when V
CC
and V
IO
again rise to their operating ranges. See Figure 9.2 on page 72. If during a voltage drop the V
CC
stays above
V
LKO
maximum the part will stay initialized and will work correctly when V
CC
is again above V
CC
minimum. If
the part locks up from improper initialization, a hardware reset can be used to initialize the part correctly.
Normal precautions must be taken for supply decoupling to stabilize the V
CC
and V
IO
power supplies. Each
device in a system should have the V
CC
and V
IO
power supplies decoupled by a suitable capacitor close to
the package connections (this capacitor is generally on the order of 0.1 µF). At no time should V
IO
be greater
then 200 mV above V
CC
(V
CC
 V
IO
- 200 mV).
