The iC-DX can be operated in high-side, low-side 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.

TIMING DESCRIPTION
..30V
VB
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
4 µs will be propagated to the output but with an addi-
tional propagation delay of 1.2 µs maximum. The re-
sulting maximum propagation delay is 5.2 µs (cf. Elec-
trical Characteristics No. 305).
