NOTES:
1. Minimum DC voltage is 0.5V on input/output pins.During transitions, this level may undershoot to 2.0Vfor periods <20 ns. Maximum DC voltage on input/output pins isV_CC + 0.5V which, during transitions, may overshoot to V_CC + 2.0V for periods <20 ns.
2. Maximum DC voltage on VPP may overshoot to +14.0V for periods <20 ns. Maximum DC voltage on RP# or A9 may overshoot to 13.5V for periods <20 ns.
3. Output shorted for no more than one second. No more than one output shorted at a time.</sup>
