Description
The HCPL-2300/HCPL-0300
optocoupler combines an 820 nm
AlGaAs photon emitting diode
with an integrated high gain
photon detector. This
combination of Agilent designed
and manufactured semiconductor
devices brings new high
performance capabilities to
designers of isolated logic and
data communication circuits.
The new low current, high speed
AlGaAs emitter manufactured
with a unique diffused junction,
has the virtue of fast rise and fall
times at low drive currents.
Figure 6 illustrates the propaga-
tion delay vs. input current
characteristic. These unique

characteristics enable this device
to be used in an RS-232-C inter-
face with ground loop isolation
and improved common mode
rejection. As a line receiver, the
HCPL-2300/HCPL-0300 will
operate over longer line lengths
for a given data rate because of
lower IF and VF specifications.
The output of the shielded inte-
grated detector circuit is an open
collector Schottky clamped tran-
sistor. The shield, which shunts
capacitively coupled common
mode noise to ground, provides a
guaranteed transient immunity
specification of 100 V/µs. The
output circuit includes an
optional integrated 1000 pull-
up resistor for the open collector.
This gives designers the flexibility
to use the internal resistor for
pull-up to five volt logic or to use
an external resistor for connec-
tion to supply voltages up to 18 V
(CMOS logic voltage).
The Electrical and Switching
Characteristics of the
HCPL-2300/HCPL-0300 are
guaranteed over a temperature
range of -40°C to 85°C. This
enables the user to confidently
design a circuit which will
operate under a broad range of
operating conditions.

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output
continuous voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table
(if applicable), your equipment level safety specification, or Agilent Application Note 1074, “Optocoupler Input-Output Endurance
Voltage.”
Notes:
1. Bypassing the power supply line is
required with a 0.1 µF ceramic disc
capacitor adjacent to each optocoupler
as illustrated in Figure 19. The power
supply bus for the optocoupler(s)
should be separate from the bus for
any active loads, otherwise a larger
value of bypass capacitor (up to
0.5 µF) may be needed to suppress
regenerative feedback via the power
supply.
2. Peaking circuits may produce transient
input currents up to 100 mA, 500 ns
maximum pulse width, provided
average current does not exceed 5 mA.
3. Device considered a two terminal
device: pins 1, 2, 3, and 4 shorted
together, and pins 5, 6, 7, and 8
shorted together.
4. The tPLH propagation delay is
measured from the 50% point on the
trailing edge of the input pulse to the
1.5 V point on the trailing edge of the
output pulse.
5. The tPHL propagation delay is
measured from the 50% point on the
leading edge of the input pulse to the
1.5 V point on the leading edge of the
output pulse.
6. CMH is the maximum tolerable rate of
rise of the common mode voltage to
assure that the output will remain in a
high logic state (i.e., VOUT > 2.0 V).
7. CML is the maximum tolerable rate of
fall of the common mode voltage to
assure that the output will remain in a
low logic state (i.e., VOUT < 0.8 V).
8. CP is the peaking capacitance. Refer to
test circuit in Figure 8.
9. In accordance with UL 1577, each
optocoupler is momentary withstand
proof tested by applying an insulation
test voltage 4500 Vrms for 1 second
(leakage detection current limit,
II-O 5 µA). This test is performed
before the 100% production test for
partial discharge (Method b) shown in
the IEC/EN/DIN EN 60747-5-2

applicable.

Applications
The HCPL-2300/HCPL-0300
optocoupler has the unique
combination of low 0.5 mA LED
operating drive current at a
5 MBd speed performance. Low
power supply current
requirement of 10 mA maximum
at 5.25 V and the ability to
provide isolation between logic
systems fulfills numerous
applications ranging from logic
level translations, line receiver
and party line receiver
applications, microprocessor I/O
port isolation, etc. The open col-
lector output allows for wired-OR
arrangement. Specific interface
circuits are illustrated in Figures
12-16, and 18 with correspond-
ing component values, perform-
ance data and recommended
layout in Figures 17 and 19.
For -40°C to 85°C operating
temperature range, a mid-range
LED forward current (IF) of
0.625 mA is recommended in
order to prevent overdriving the
integrated circuit detector due to
increased LED efficiency at
temperatures between 0°C and
-40°C. For narrower temperature
range of 0°C to 85°C, a suggested
operating LED current of
0.75 mA is recommended for the
mid-range operating point and for
minimal propagation delay skew.
A peaking capacitance of 20 pF
in parallel with the current
limiting resistor for the LED
shortens tPHL by approximately
33% and tPLH by 13%. Maintain-
ing LED forward voltage (VF)
below 0.8 V will guarantee that
the HCPL-2300/HCPL-0300
output is off.
The recommended shunt drive
technique for TTL/LSTTL/CMOS
of Figure 12 provides for optimal
speed performance, no leakage
current path through the LED,
and reduced common mode
influences associated with series
switching of a “floating” LED.
Alternate series drive techniques
with either an active CMOS
inverter or an open collector TTL/
LSTTL inverter are illustrated in
Figures 13 and 14 respectively.
Open collector leakage current of
250 µA has been compensated by
the 3.16 Kresistor (Figure 14)
at the expense of twice the
operating forward current.
An application of the HCPL-2300/
HCPL-0300 as an unbalanced line
receiver for use in long line
twisted wire pair communication
links is shown in Figure 15. Low
LED IF and VF allow longer line
length, higher speed and multiple
stations on the line in comparison
to higher IF, VF optocouplers.
Greater speed performance along
with nearly infinite common
mode immunity are achieved via
the balanced split phase circuit
of Figure 16. Basic balanced
differential line receiver can
be accomplished with one
HCPL-2300/HCPL-0300 in
Figure 16, but with a typical
400 V/µs common mode
immunity. Data rate versus
distance for both the above
unbalanced and balanced line
receiver applications are com-
pared in Figure 17. The RS-232-C
interface circuit of Figure 18

provides guaranteed minimum
common mode immunity of
100 V/µs while maintaining the
2:1 dynamic range of IF.
A recommended layout for use
with an internal 1000 resistor
or an external pull-up resistor
and required VCC bypass capaci-
tor is given in Figure 19. VCC1 is
used with an external pull-up
resistor for output voltage levels
(VO) greater than or equal to 5 V.
As illustrated in Figure 19, an
optional VCC and GND trace can
be located between the input
and the output leads of the
HCPL-2300/HCPL-0300 to
provide additional noise
immunity at the compromise of
insulation capability (VI-O).
