Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix -320E corresponds to the required RoHS compliance status and gull-wing packaging variant. Confirm that the operating temperature range of 0°C to +70°C meets the environmental requirements of the target application. Ensure the 16 mA forward current drive capability is supported by the source circuitry to maintain optimal current transfer ratio performance.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel of high-speed isolation is required with a phototransistor output. It is appropriate for designs needing 3750 Vrms isolation and 1 Mb/s data throughput. Consider the PDIP-8 package constraints and the 0°C to +70°C operating range during thermal management planning. Compare against other HCPL-450x series variants if different output types or speed ratings are needed.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers from Broadcom Limited. The series is designed for robust digital isolation in industrial and commercial applications. The HCPL-4502-320E specifically offers a balance of speed and isolation voltage in a standard DIP package, serving as a reliable solution for noise-sensitive digital circuits.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-4502 (without suffix) is a related variant in the same family. The HCPL-2531-360E is a dual-channel alternative but differs in channel count. Verify pinout compatibility and specific electrical tolerances before substituting with any other optocoupler models.
