Applications
• Inverter circuits and Intelligent Power Module (IPM)
interfacing: High Common Mode Transient immunity
(> 10 kV/µs for an IPM load/drive) and (t
PLH
- t
PHL
)
Specied (see Power Inverter Dead Time section)
• Line receivers: Short propagation delays and low in-
put-output capacitance
• High speed logic ground isolation: TTL/TTL, TTL/
CMOS, TTL/LSTTL
• Replaces pulse transformers: Save board space and
weight
• Analog signal ground isolation: Integrated photode-
tector provides improved linearity over phototransis-
tors
A 0.1 µF bypass capacitor between pins 5 and 8 is recommended.

HCPL-4504 Functional Diagram
Description
The HCPL-4504 and HCPL-0454 contain a GaAsP LED
while the HCPL-J454 and HCNW4504 contain an AlGaAs
LED. The LED is optically coupled to an integrated high
gain photo detector.
The HCPL-4504 series has short propagation delays and
high CTR. The HCPL-4504 series also has a guaranteed
propagation delay dierence (t
PLH
-t
PHL
). These features
make the HCPL-4504 series an excellent solution to IPM
inverter dead time and other switching problems. The
CTR, propagation delay, and CMR are specied both for
TTL and IPM conditions which are provided for ease of
application. These single channel, diode-transistor opto-
couplers are available in 8-Pin DIP, SO-8, and Widebody
package congurations. An insulating layer between a
LED and an integrated photodetector provide electrical
insulation between input and output. Separate connec-
tions for the photodiode bias and output-transistor col-
lector increase the speed up to a hundred times that of
a conventional phototransistor coupler by reducing the
base collector capacitance.
