WP#/ACC is –0.5 V. During voltage transitions, OE#,
WP#/ACC, and RESET# may overshoot V
for periods of up to 20 ns. See Figure 7. Maximum DC
input voltage on pin RESET# is +12.5 V which may
overshoot to +14.0 V for periods up to 20 ns. Maximum
DC input voltage on WP#/ACC is +9.5 V which may
overshoot to +12.0 V for periods up to 20 ns.
