1 tDLH propagation delay is measured from the time of the input rising logic high voltage threshold, VIH, to the output rising 10% level of the VOUT signal. tDHL propagation
delay is measured from the input falling logic low voltage threshold, VIL, to the output falling 90% threshold of the VOUT signal. See Figure 22 for waveforms of propagation delay
parameters.
2 Static CMTI is the largest dv/dt between GND1 and GND2, with inputs held either high or low, such that the output voltage remains either above 0.8 × VDD2 for output high
or 0.8 V for output low. Operation with transients above recommended levels can cause momentary data upsets.
3 Dynamic CMTI is the largest dv/dt between GND1 and GND2 with the switching edge coincident with the transient test pulse. Operation with transients above the
recommended levels can cause momentary data upsets.
