Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix TA indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Lite-On Inc. Ensure the part number matches LTV-844S-TA exactly to avoid confusion with tube-packaged variants or different output types within the same family. Check RoHS compliance status if required by your manufacturing standards.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when four independent isolated channels are required in a compact surface-mount footprint. The transistor output type is suitable for logic-level interfacing. Consider the 5000Vrms isolation barrier for noise immunity in high-voltage environments. Verify that the 35V collector-emitter voltage meets the load requirements of the destination circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the Lite-On LTV series of optocouplers, designed for general-purpose isolation tasks. The LTV-844S variant specifically offers four channels, distinguishing it from dual-channel models like the LTV-843S. The TA suffix denotes the reel packaging format, differing from the standard tube packaging found in other versions of the same electrical specification.
