EXTERNAL CLOCK DRIVE WAVEFORMS

272405 – 23

AC TESTING INPUT OUTPUT WAVEFORMS

272405 – 24

AC Testing inputs are driven at 35V for a logic ‘‘1’’ and

045V for a logic ‘‘0’’ Timing measurements are made

at 20V for a logic ‘‘1’’ and 08V for logic ‘‘0’’

FLOAT WAVEFORMS

272405 – 25

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

EXPLANATION OF AC SYMBOLS

Each symbol is two pairs of letters prefixed by ‘‘T’’

for time The characters in a pair indicate a signal

and its condition respectively Symbols represent

the time between the two signalcondition points
