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

is +12.5 V which may overshoot to +13.5 V for periods up
to 20 ns.
