AC Testing Input/Output Waveforms(1) Float Waveforms(1)
VCC - 0.5V
0.2VCC + 0.9V
TEST POINTS
0.45V
0.2VCC - 0.1V
Note: 1. AC Inputs during testing are driven at VCC -
0.5V 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.

Points
VOL + 0.1V
VOL + 0.1V
Note: 1. For timing purposes, a port pin is no longer
floating when a 100mV change from load
voltage occurs. A port pin begins to float
when a 100mV change from the loaded
VOH/VOL level occurs.
