Application Information
Bypassing and PC Board Layout
The HCPL-772X/072X optocouplers are extremely easy
to use. No external interface circuitry is required because
the HCPL-772X/072X use high-speed CMOS IC technol-
ogy allowing CMOS logic to be connected directly to the
inputs and outputs.
As shown in Figure 10, the only external components

Propagation Delay is a figure of merit which describes
how quickly a logic signal propagates through a sys-
tem. The propaga tion delay from low to high (t

required for proper operation are two bypass capaci-
tors. Capacitor values should be between 0.01 μF and
0.1 μF. For each capacitor, the total lead length between
both ends of the capacitor and the power-supply pins
should not exceed 20 mm. Figure 11 illustrates the rec-
