AC Testing Input/Output Waveforms
AC inputs during testing are driven at V
CC
- 0.5 for a logic “1” and 0.45V for a logic “0”.
Timing measurement are made at V
IH
min for a logic “1” and V
IL
max for a logic “0”.
Float Waveforms

Float Waveforms
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 V
