AC TESTING INPUT OUTPUT WAVEFORMS

FLOAT WAVEFORMS

272356 – 27

272356 – 28

AC Inputs during testing are driven at VCCb0 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’’

272356 – 29

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

IOL IOH e g20 mA (-L IOL IOH e g10 mA)
