NOTES:
1.
Stesses 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 input voltage on pins A9, OE#, RESET#, and WP#/ACC is –0.5V.
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,
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.
