iC-DXC3

DIGITAL SENSOR I/O DRIVER

Rev B2, Page 10/12

TIMING DESCRIPTION

The iC-DXC3 has a built-in spurious pulse suppres-

sion that prevents short (undesired) pulses at the input

pins from reaching the output. Every pulse at OE or

NIN pins shorter than 1.6 µs (cf. Electrical Character-

istics No. 306) will be ignored and the output will not

react. The minimum required pulse length to be sure

that the output reacts is 4 µs (cf. Electrical Character-

istics No. 307). That means that every pulse longer

than 4 µs will be propagated to the output but with an

additional propagation delay of 1.2 µs maximum. The

resulting maximum propagation delay is 5.2 µs (cf. Elec-

trical Characteristics No. 305).

OPERATING MODES

Erroneous description on page 8 ("In case of a short circuit at OUT and resulting temper-

ature shutdown, logic level of MON will be undefined.") removed, as MON output is not

affected by thermal shutdown.
