Due to the timing differences for the rising and the falling edge there will be a slight
difference between the length of the input pulse and the length of the output pulse. It can
be calculated using the following formulas:
• ∆tHS = (tdr(HS) + 0.5 tr(HS)) - (tdf(HS) + 0.5 tf(HS))
• ∆tLS = (tdf(LS) + 0.5 tf(LS)) - (tdr(LS) + 0.5 tr(LS)).
