Notes:

1. Minimum DC voltage on input or I/O pins is -0.5 V. During

voltage transitions, input or I/O pins may undershoot VSS

to -2.0 V for periods of up to 20 ns. Maximum DC voltage

on input or I/O pins is

VCC +0.5 V. During voltage

transitions, input or I/O pins may overshoot to VCC +2.0 V

for periods up to 20 ns. See Figure 7 and Figure 8.

2. Minimum DC input voltage on pins A9, OE, and RESET is

-0.5 V. During voltage transitions, A9, OE, and RESET

may undershoot VSS to -2.0 V for periods of up to 20 ns.

Maximum DC input voltage on pin A9 is +12.5 V which

may overshoot to 14.0 V for periods up to 20 ns. See

Figure 7 and Figure 8.

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.
