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
optocoupler is connected directly

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
communication up to 12 MBd. As
shown in Figure 22, a PROFIBUS
Controller (PBC) establishes the
connection of a field automation
unit (control or central processing
station) or a field device to the
transmission medium. The PBC
consists of the line transceiver,
optical isolation, frame character
transmitter/receiver (UART), and
the FDL/APP processor with the
interface to the PROFIBUS user.
to the CAN transceiver. Two
bypass capacitors (with values
between 0.01 and 0.1
μ
F) are
required and should be located as
close as possible to the input and
output power-supply pins of the
HCPL-772X/072X. For each

MEDIUM
capacitor, the total lead length
between both ends of the
capacitor and the power supply
pins should not exceed 20 mm.
The bypass capacitors are
required because of the high-
speed digital nature of the signals
inside the optocoupler.
