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 V
SS
to –2.0 V for periods of up to 20 ns. Maximum
DC voltage on input or I/O pins is V
CC
+ 0.5 V. See Figure 10. During voltage
transitions, input or I/O pins may 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# may 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 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.
