ISP321-4XG

Transistor, Photovoltaic Output Optoisolators Overview

The ISP321-4XG is a quad optocoupler manufactured by Isocom Components 2004 LTD. It features four independent channels within a single 16-pin DIP package, designed for high-density mounting applications. The device integrates infrared light-emitting diodes with NPN silicon phototransistor outputs to provide galvanic isolation. Key electrical specifications include a 5300Vrms isolation voltage rating and a collector current capacity of 50 mA per channel. This configuration supports efficient signal transmission across isolated circuits while maintaining compact board space requirements.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (XG) against official Isocom Components documentation to confirm pinout compatibility and packaging type. Ensure the procurement source is an authorized distributor to guarantee component authenticity and traceability. Cross-reference the datasheet revision date to align with current manufacturing standards and availability constraints.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required within a constrained PCB area. The 16-pin DIP format suits through-hole assembly processes. Confirm that the 50 mA output current capability meets the load requirements of the downstream circuitry. Evaluate the 5300Vrms isolation rating against the system's voltage stress conditions to ensure adequate safety margins.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP321 series represents Isocom Components' range of infrared optoelectronic isolators. The ISP321-4XG specifically addresses the need for quad-channel isolation in a standard DIP package. This model complements single-channel variants like the ISP321-1G by offering higher integration density for complex signal routing applications without increasing component count significantly.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes must match the quad-channel configuration, 16-pin DIP package, and NPN transistor output type. Verify equivalent isolation voltage ratings and current transfer ratios. Consult manufacturer cross-reference lists for confirmed compatible part numbers from Isocom or other qualified suppliers.
