HCNW4504

High CMR, High Speed Optocouplers

Currently Viewing:

It contains 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 difference (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 specified both for TTL and IPM conditions which are provided for ease of application. This single channel, diode-transistor optocoupler is available in a Widebody package. An insulating layer between a LED and an integrated photodetector provides 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.
