Notes:

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

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

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 VCC +0.5 V.

See Figure 10. During voltage transitions, input or I/O

pins can overshoot to V

CC +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# can overshoot V

SS 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 can overshoot to +14.0 V for periods up to

20 ns.

3. No more than one output can 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” can 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 can affect device reliability.
