Notes:

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

input or I/O pins may overshoot 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. See Figure 10. During voltage

transitions, input or I/O pins may overshoot to VCC +2.0 V for periods up to 20 ns.

See Figure 11.

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

voltage transitions, A9, OE#, ACC, and RESET# may overshoot VSS to –2.0 V for

periods of up to 20 ns. See Figure 10. Maximum DC input voltage on pin A9, OE#,

ACC, and RESET# is +12.5 V which may overshoot to +14.0 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.

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 con-

ditions for extended periods may affect device reliability.

Notes:

1. Operating ranges define those limits between which the functionality of the device

is guaranteed.

2. See Ordering Information section for valid VCC/VIO range combinations. The I/Os

will not operate at 3 V when VIO = 1.8 V.
