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 Vcc + 0.5V. During voltage transitions, outputs
may overshoot to V
CC
+ 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.
