The ACPL-H342 with the Anti-Cross feature has a PDDMIN
of -10ns and a PDDMAX of -200ns. Since the PDD is always
a negative value, the tPHLMAX is always faster than tPLHMIN.
Thus this simplified the design without having to add any
amount of delay for the input LEDs as shown in Figure 39.

= Minimum Dead Time
Figure 40. Determining maximum dead time
Dead time is the time period during which both the
high(Q1) and low(Q2) side transistor are off. During this
time, no work is done and this reduces the efficiency of
the inverter or motor drive. The minimum and maximum
dead time is shown in Figure 39 and 40 and is equivalent
to the PDDMIN and PDDMAX . Due to the smaller PDD and
skewed propagation delay configuration, ACPL-H342
shows a smaller maximum dead time as compared to its
predecessor, HCPL-3120 as shown in figure 41 and hence
an improve in efficiency. Note that the propagation delays
used to calculate PDD and dead time are taken at equal
temperature and test conditions since the optocou-
plers under consideration are typically mounted in close
proximity to each other and are switching identical IGBTs.
