HCPL-4504/J454/0454, HCNW4504
High CMR, High Speed Optocouplers
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 diff erence (tPLH-tPHL). 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 specifi ed both for TTL and IPM conditions which are provided for ease of application. These single channel, diode-transistor optocouplers are available in 8-Pin DIP, SO-8, and Widebody package confi gurations. An insulating layer between a LED and an integrated photodetector provide electrical insulation between input and output.
Separate connections for the photodiode bias and output-transistor collector increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base collector capacitance.
Features
• Short propagation delays for TTL and IPM applications
• 15 kV/μs minimum Common Mode Transient immunity at VCM = 1500 V for TTL/load drive
• High CTR at TA = 25°C

Applications
• Inverter circuits and Intelligent Power Module (IPM) interfacing: High Common Mode Transient immunity (> 10 kV/μs for an IPM load/drive) and (tPLH - tPHL) Specifi ed (see Power Inverter Dead Time section)
• Line receivers: Short propagation delays and low input-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 photodetector provides improved linearity over phototransistors
