TIMING DESCRIPTION
The iC-DX has a built-in spurious pulse suppression
that prevents short (undesired) pulses at the input pins
from reaching the output.

the output will not react. The minimum required pulse
length to be sure that the output reacts is 4 µs (cf. Elec-
trical Characteristics No. 307). That means that every
pulse longer than 4 µs will be propagated to the out-
put but with an additional propagation delay of 1.2 µs
maximum. The resulting maximum propagation delay
is 5.2 µs (cf. Electrical Characteristics No. 305).
