NOTES:

1.

Minimum DC voltage on input or input or I/Os is -0.5V. During voltage transitions,

voltage on input or I/Os us VCC + 0.5V. During voltage transitions, input or I/O pins

2.

Minimum DC input voltage on pins A9, OE#, and ACC is 0.5V. During voltage

Maximum DC input voltage on pin A9, OE#, and ACC is +12.5V which may overshoot

to +14.0V for periods up to 20ns

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 Maxium 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 the data sheet is not implied. Exposure of the device to absolute maxium rating

conditons for extended peroids may affect device reliability
