HCPL-2300, HCPL-0300
8 MBd Low Input Current Optocoupler
Data Sheet
Description
The HCPL-2300/HCPL-0300 optocoupler combines
an 820 nm AlGaAs photon emitting diode with an
integrated high gain photon detector. This combina-tion
of Avago designed and manufactured semiconductor
devices brings new high performance capabilities to
designers of isolated logic and data communication cir-
cuits.
The new low current, high speed AlGaAs emitter manu-
factured with a unique diused junction, has the virtue
of fast rise and fall times at low drive currents. Figure 6 il-
lustrates the propagation delay vs. input current charac-
teristic. These unique characteristics enable this device
to be used in an RS-232-C interface with ground loop iso-
lation 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 specications.

• Internal shield for guaranteed common mode
rejection
• Schottky clamped, open collector output with
optional integrated pull-up resistor

The output of the shielded integrated detector circuit is
an open collector Schottky clamped transistor. The shield,
which shunts capacitively coupled common mode noise
to ground, provides a guaranteed transient immunity
specication of 100 V/µs. The output circuit includes an
optional integrated 1000 Ω pull-up resistor for the open
collector. This gives designers the exibility to use the
internal resistor for pull-up to ve volt logic or to use an
external resistor for connection 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 tempera-
ture range of -40°C to 85°C. This enables the user to con-
dently design a circuit which will operate under a broad
range of operating conditions.

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 with-
stand 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 dis-
charge (Method b) shown in the IEC/EN/DIN EN 60747-5-2 Insula-
tion Characteristics Table, if 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 abil-
ity to provide isolation between logic systems fullls
numerous applications ranging from logic level transla-
tions, line receiver and party line receiver applications,
microprocessor I/O port isolation, etc. The open collector
output allows for wired-OR arrangement. Specic inter-
face circuits are illustrated in Figures 12-16, and 18 with
corresponding component values, performance 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 recommend-
ed in order to prevent overdriving the integrated circuit
detector due to increased LED eciency 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 cur-
rent limiting resistor for the LED shortens tPHL by approxi-
mately 33% and tPLH by 13%. Maintaining LED forward
voltage (VF) below 0.8 V will guarantee that the HCPL-
2300/HCPL-0300 output is o.
The recommended shunt drive technique for TTL/LSTTL/
CMOS of Figure 12 provides for optimal speed perfor-
mance, no leakage current path through the LED, and re-
duced common mode inuences associated with series
switching of a “oating” LED. Alternate series drive tech-
niques 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 KΩ resistor
(Figure 14) at the expense of twice the operating forward
current.
An application of the HCPL-2300/HCPL-0300 as an un-
balanced 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 innite common mode immu-
nity are achieved via the balanced split phase circuit
of Figure 16. Basic balanced dierential line re-
ceiver 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 dis-
tance for both the above unbalanced and balanced line
receiver applications are compared 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 Ω
resistor or an external pull-up resistor and required VCC
bypass capacitor 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).
