270431 – 12

270431 – 13

AC Inputs During Testing are Driven at VCCb0 5 for a Logic ‘‘1’’

and 0 45V for a Logic ‘‘0’’ Timing Measurements are made at VIH

Min for a Logic ‘‘1’’ and VIL 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 VOH VOL Level occurs
