ISP847D is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is OPTOISO 5.3KV 4CH TRANS 16-DIP. Review the specifications below when checking this part for your BOM.
The ISP847D is a quad optocoupler featuring four independent channels within a single 16-pin DIP package. It integrates infrared light-emitting diodes with NPN silicon phototransistor outputs to provide electrical isolation between input and output circuits. The device offers a high isolation voltage rating of 5300Vrms, ensuring robust signal transmission in electrically noisy environments while maintaining compact board space efficiency through its high-density mounting configuration.
Verify the specific suffix designation against official Isocom documentation to confirm pinout compatibility and insulation class requirements. Ensure the selected variant matches the required isolation voltage specifications for the target application environment. Cross-reference datasheet parameters such as current transfer ratio and propagation delay before integration into final designs.
Select this component when multiple isolated signal paths are required in a confined footprint. The quad configuration reduces assembly complexity compared to discrete single-channel units. Evaluate the 5300Vrms isolation rating against system safety standards. Confirm that the NPN output characteristics align with the downstream logic or driver interface requirements.
Isocom Components specializes in infrared optoelectronic devices, including optocouplers and optoswitches. The ISP847D belongs to their family of high-density mounting isolators designed to replace legacy components. These devices are manufactured to meet global industry standards, offering alternatives for parts no longer produced by other manufacturers.
