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. See Figure 6. 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.

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

is –0.5 V. During voltage transitions, A9, OE#, and

RESET# may overshoot VSS to –2.0 V for periods of up to

20 ns. See Figure 6. Maximum DC input voltage on pin A9

is +12.5 V which may overshoot to +13.5 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.

Note: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.
