AC TESTING INPUT OUTPUT WAVEFORMS
FLOAT WAVEFORMS
272267 – 17
272267 – 18
AC Testing inputs are driven at 3 5V for a logic ‘‘1’’ and
0 45V for a logic ‘‘0’’ Timing measurements are made
at 2 0V for a logic ‘‘1’’ and 0 8V for logic ‘‘0’’
272267 – 19
For timing purposes a Port Pin is no longer floating
when a 150 mV change from load voltage occurs and
begins to float when a 150 mV change from the loading
VOH VOL level occurs IOL IOH s 15 mA
