Applications

Description

The HCPL05XX, and HCPL04XX optocouplers consist of

an AlGaAs LED optically coupled to a high speed photo-

detector transistor housed in a compact 8-pin small out-

line 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. The

HCPL04XX devices do not have the base bonded out to

a lead for additional noise margin. The HCPL053X

devices have two channels per package for optimum

mounting density.
