HCPL-0454 - AVAGO

HCPL-0454 High Speed Optocouplers

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 difference (tPLH-tPHL). These features make the HCPL-4504 se.

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. These single channel, diode-transistor optocouplers are available in 8-Pin DIP, SO-8, and Widebody package configurations. 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.
