AC inputs during testing are driven at Vcc – 0.5 for a logic
“1” and 0.45 V for a logic “0”. Timing measurements are
made at VIH min for a logic “1” and VIL max for a logic
“0”.
For timing purposes as 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. Iol/IoH
