During voltage transitions, A9, OE#, WP#/ACC, and RESET# may overshoot VSS to
–2.0V for periods of up to 20 ns. See Figure 8. Maximum DC input voltage on pin A9,
This parameter is guaranteed by design but not tested.
OE#, and RESET# is +12.5V which may overshoot to +14.0V for periods up to 20 ns.
Maximum DC input voltage on WP#/ACC is +9.5V which may overshoot to +12.0V
for periods up to 20 ns.
