1 RGON and RGOFF are the external gate resistors in the test.
2 tDLH propagation delay is measured from the time of the input rising logic high threshold, VIH, to the output rising 10% threshold of the VOUT signal. tDHL propagation
delay is measured from the input falling logic low threshold, VIL, to the output falling 90% threshold of the VOx signal. See Figure 24 for waveforms of the propagation delay
parameters.
3 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 24 for waveforms of the propagation delay parameters.
4 tPSKHL is the magnitude of the worst case difference in tDHL that is measured between units at the same operating temperature, supply voltages, and output load within
the recommended operating conditions. See Figure 24 for waveforms of the propagation delay parameters.
5 tPSKLH is the magnitude of the worst case difference in tDLH that is measured between units at the same operating temperature, supply voltages, and output load within
the recommended operating conditions. See Figure 24 for waveforms of the propagation delay parameters.
6 Static common-mode transient immunity (CMTI) is defined as 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.
7 Dynamic common-mode transient immunity (CMTI) is defined as 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.
