Notes:

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

Dur ing voltage transitions, input or I/O pins may

overshoot V

SS to –2.0 V for per iods of up to 20 ns.

Maximum DC voltage on input or I/O pins is V

CC +0.5 V.

See Figure 8. During voltage transitions, input or I/O pins

may overshoot to V

CC +2.0 V for periods up to 20 ns. See

Figure 9.

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

and WP#/ACC is –0.5 V. During voltage transitions, A9,

OE#, WP#/ACC, and RESET# may overshoot V

SS to

–2.0 V for periods of up to 20 ns. See Figure 8. Maximum

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

overshoot to +14.0 V for periods up to 20 ns. Maximum

DC input voltage on WP#/ACC is +9.5 V which may

overshoot to +12.0 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

conditions for extended periods may affect device reliability.
