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:
• Δ t
HS
= (t
dr(HS)
+ 0.2 t
r(HS)
) - (t
df(HS)
+ 0.8 t
f(HS)
)
• Δ t
LS
= (t
df(LS)
+ 0.2 t
f(LS)
) - (t
dr(LS)
+ 0.8 t
r(LS)
).
