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 fulfills
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. Specific 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 (I
ed 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 cur-
rent limiting resistor for the LED shortens t

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 influences associated with series
switching of a “floating” 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
