Notes:
1. Minimum DC voltage is -0.5V on input/output pins. During Transitions, inputs may undershoot to -2.0V for periods < 20nS. Maximum DC voltage on input/output
pins is Vcc + 0.5V, which may overshoot to Vcc + 2.0V for periods < 20nS.
2. Maximum DC voltage on Vpp may overshoot to +14.0V for periods < 20nS. Maximum DC voltage on RP or A
9
may overshoot to V
CC
+ 0.5V for periods <20nS
3. Output shorted for no more than 1 second. No more than one output shorted at one time.
NOTICE: Stresses above those listed under "Absolute Maximums Rating" may cause permanent damage. These are stress rating only. Operation beyond the "Oper-
ation Conditions" is not recommended and extended exposure beyond the "Operation Conditions" may effect device reliability.
