NOTES:
1. Stresses above the absolute maximum rating may cause permanent damage to the
device. Extended operation at the maximum levels may degrade performance and
affect reliability.
2. Minimum DC voltage on input or I/O pins is -0.5V. During voltage transitions, inputs
may overshoot V
SS
to -2.0 V for periods of up to 20ns. Maximum DC voltage on
output and I/O pins is V
CC
+ 0.5V. During voltage transitions, outputs may overshoot
to Vcc + 2.0 V for periods of up to 20ns.
3. Minimum DC input voltage on A9 pin is -0.5V. During voltage transitions, A9 may
overshoot Vss to -2V for periods of up to 20ns. Maximum DC input voltage on A9 is
+13.5V which may overshoot to 14.0 V for periods up to 20ns.
