TIMING DESCRIPTION
..30V
VB
The iC-DXC 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 NIN
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).

As a general rule our developments, IPs, principle circuitry and range of Integrated Circuits are suitable and specifically designed for appropriate use in technical
applications, such as in devices, systems and any kind of technical equipment, in so far as they do not infringe existing patent rights. In principle the range of
use is limitless in a technical sense and refers to the products listed in the inventory of goods compiled for the 2008 and following export trade statistics issued
annually by the Bureau of Statistics in Wiesbaden, for example, or to any product in the product catalogue published for the 2007 and following exhibitions in
Hanover (Hannover-Messe).
We understand suitable application of our published designs to be state-of-the-art technology which can no longer be classed as inventive under the stipulations
of patent law. Our explicit application notes are to be treated only as mere examples of the many possible and extremely advantageous uses our products can
be put to.
