Application Information
Bypassing and PC Board
Layout
The HCPL-x710 optocouplers are
extremely easy to use. No
external interface circuitry is
required because the HCPL-x710
use high-speed CMOS IC
technology allowing CMOS logic
to be connected directly to the
inputs and outputs.
As shown in Figure 12, the only
external components required for
proper operation are two bypass
capacitors. Capacitor values
should be between 0.01
μ
F and
0.1
μ
F. For each capacitor, the
total lead length between both
ends of the capacitor and the
power-supply pins should not
exceed 20 mm. Figure 13
illustrates the recommended
printed circuit board layout for
the HPCL-x710.

Propagation Delay, Pulse-
Width Distortion and
Propagation Delay Skew
Propagation Delay is a figure of
merit which describes how
quickly a logic signal propagates
through a system. The propaga-
tion delay from low to high (t
PLH
)
is the amount of time required for
an input signal to propagate to
the output, causing the output to
change from low to high.
Similarly, the propagation delay
from high to low (t
PHL
) is the
amount of time required for the
input signal to propagate to the
output, causing the output to
change from high to low. See
Figure 14.
