Power Supplies and Bypassing
The recommended DeviceNet application circuit is
shown in Figure 21. Since the HCPL-772X/072X are fully
compatible with CMOS logic level signals, the optocoup-
ler is connected directly to the CAN transceiver. Two by-
pass capacitors (with values between 0.01 and 0.1 μF)
are required and should be located as close as possible
Figure 21. Recommended DeviceNet application circuit.
Implementing PROFIBUS with the HCPL-772X/072X
An acronym for Process Fieldbus, PROFIBUS is essentially
a twisted-pair serial link very similar to RS-485 capable
of achieving high-speed communi cation up to 12 MBd.
As shown in Figure 22, a PROFIBUS Control ler (PBC) es-
tablishes the connec tion of a field automation unit (con-
trol or central processing station) or a field device to
the transmission medium. The PBC consists of the line
transceiver, optical isolation, frame character transmit-
ter/receiver (UART), and the FDL/APP processor with the
interface to the PROFIBUS user.

to the input and output power-supply pins of the HCPL-
772X/072X. For each capacitor, the total lead length be-
tween both ends of the capacitor and the power supply
pins should not exceed 20 mm. The bypass capac itors
are required because of the high-speed digital nature of
the signals inside the optocoupler.
