ISP621-4XGR

Transistor, Photovoltaic Output Optoisolators Overview

The ISP621-4XGR is a quad-channel optocoupler manufactured by Isocom Components. It features four independent channels within a single package, providing galvanic isolation between input and output circuits. The device utilizes a phototransistor output configuration for signal transmission. It is designed for through-hole mounting in a DIP-16 package. Key electrical parameters include a maximum forward voltage of 1.3V per channel, a typical rise time of 2μs, and a typical fall time of 3μs. The unit offers an isolation voltage of 5300Vrms. The current transfer ratio ranges from a minimum of 100% to a maximum of 6%. Operating temperatures span from -30°C to 100°C.
