Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '060' against the manufacturer's datasheet to confirm pinout compatibility and RoHS status, as suffixes often denote packaging or regulatory variations. Ensure the required operating temperature range aligns with the component's specified limits. Cross-reference the isolation voltage rating with system safety requirements before finalizing procurement decisions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a high data rate of 1 Mb/s is required for single-channel isolation. It is suitable for applications needing moderate output drive capability with an 8 mA collector current. Consider the PDIP-8 package constraints for PCB layout. Compare against the HCPL-4502 if inverted logic output is preferred over the standard non-inverted configuration provided by this model.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers from Broadcom Limited. The series includes variants like the HCPL-4502 and HCPL-4503, which share similar internal architectures but differ in output logic polarity. These devices are designed to replace slower conventional phototransistor couplers in high-speed digital communication applications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-4503#060 is a direct equivalent part number variant. Verify compatibility with HCPL-4503 models differing only by lead-free or packaging suffixes. Do not substitute with HCPL-4502 without verifying logic inversion requirements.
