The HCPL05XX and HCPL04XX optocouplers consist of an AlGaAs LED optically coupled to a high-speed photodetector transistor in a compact 8-pin small-outline encapsulation. A separate connection for photodiode biasing reduces the base-collector capacitance of the input transistor and is orders of magnitude faster than conventional phototransistors. The HCPL04XX devices do not have a lead-bonded substrate for greater noise margin. Each encapsulation of the HCPL053X device has two trenches for optimum packing density.
