HFBR-24X2 Low-Cost
5 MBd Receiver
Description
The HFBR-24X2 fiber optic
receiver is designed to operate
with the Hewlett-Packard HFBR-
14XX fiber optic transmitter and

The HFBR-24X2 receiver incor-
porates an integrated photo IC
containing a photodetector and
dc amplifier driving an open-
collector Schottky output
transistor. The HFBR-24X2 is

designed for direct interfacing to
popular logic families. The
absence of an internal pull-up
resistor allows the open-collector
output to be used with logic
families such as CMOS requiring
voltage excursions much higher
than V
CC
.
Both the open-collector “Data”
output Pin 6 and V
CC
Pin 2 are
referenced to “Com” Pin 3, 7. The
“Data” output allows busing,
strobing and wired “OR” circuit
configurations. The transmitter is
designed to operate from a single
+5 V supply. It is essential that a
bypass capacitor (0.1
μ
F
ceramic) be connected from
Pin 2 (V
CC
) to Pin 3 (circuit
common) of the receiver.
