Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific manufacturer designation, as the part number appears in databases associated with both onsemi and Fairchild Semiconductor. Confirm the package type matches the required SOP-8 form factor. Ensure the isolation voltage rating of 2500 Vrms meets the safety requirements of the target application environment before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount footprint. The 1 MBps speed suits moderate-speed digital signals, while the 2500 Vrms isolation barrier protects sensitive low-voltage circuitry from higher voltage domains. Consider the open-collector output characteristics for pull-up resistor configuration compatibility.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers. It serves as a dual-channel variant designed for applications requiring galvanic isolation between multiple signal lines. The technology utilizes light-emitting diodes and phototransistors to transmit signals across an insulating barrier without electrical contact.
