DESCRIPTION

The HCPL-0500, HCPL-0501 and HCPL-0452 optocouplers consist of an AlGaAs LED optically coupled to a high speed photodetector transistor housed in a compact 8-pin smalloutline package.

A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor.

FEATURES

• High speed-1 MBit/s

• CTR guaranteed 0-70°C

• U.L. recognized (File # E90700)

APPLICATIONS

• Line receivers

• Pulse transformer replacement

• Output interface to CMOS-LSTTL-TTL

• Wide bandwidth analog coupling
