1 Short-circuit duration less than 1 µs. Average power must conform to the limits shown in the Absolute Maximum Ratings section.
2 The minimum pulse width is the shortest pulse width at which the specified timing parameter is guaranteed.
3 The maximum data rate is the fastest data rate at which the specified timing parameter is guaranteed.
4 tDHL propagation delay is measured from the input falling logic low threshold, VIL, to the output falling 90% threshold of the VO signal. tDLH propagation delay is
measured from the time of the input rising logic high threshold, VIH, to the output rising 10% level of the VO signal. See Figure 17 for waveforms of propagation delay
parameters.
5 tPSK is the magnitude of the worst case difference in tDLH and/or tDHL that is measured between units at the same operating temperature, supply voltages, and output
load within the recommended operating conditions. See Figure 17 for waveforms of propagation delay parameters.
