AC Inputs During Testing are Driven at V_CCb0 5 for a Logic ‘‘1’’
and 0 45V for a Logic ‘‘0’’ Timing Measurements are made at V_IH
Min for a Logic ‘‘1’’ and V_IL Max for a Logic ‘‘0’’
270431 – 14
For Timing Purposes a Port Pin is no Longer Floating when a
100 mV change from Load Voltage Occurs and Begins to Float
when a 100 mV change from the Loaded V_OH V_OL Level occurs
