The iC-DX can be operated in High-Side (PNP-
Switch), Low-Side (NPN-Switch) and Push-Pull switch
mode. Figure 4 shows the high-side operation where
IN pin must be kept high and the OE pin controls the
switch. Figure 5 shows the low-side operation where
IN pin must be kept low and the OE pin controls the
switch. Figure 6 shows the push-pull operation where
OE pin must be kept high and the IN pin controls the
switch.

The iC-DX has a built-in spurious pulse suppression
that prevents short (undesired) pulses at the input pins
from reaching the output. Every pulse at OE or IN
pins shorter than 1.6 µs (cf. Electrical Characteristics
No. 306) will be ignored and the output will not re-
act. The minimum required pulse length to be sure
that the output reacts is 4 µs (cf. Electrical Characteris-
tics No. 307). That means that every pulse longer than

tional propagation delay of 1.2 µs maximum. The re-
sulting maximum propagation delay is 5.2 µs (cf. Elec-
trical Characteristics No. 305).
