ISQ74

Transistor, Photovoltaic Output Optoisolators Overview

The ISQ74 is a high-density quad optically coupled isolator manufactured by Isocom Components. It integrates four independent channels within a single 16-pin DIP package, featuring infrared light-emitting diodes paired with NPN silicon phototransistors. The device provides an isolation voltage of 5300Vrms per channel. This configuration allows for efficient signal transmission across isolated circuits while maintaining compact board space requirements.
