HCPL2231
Description
The HCPL-22XX, HCPL-02XX, and HCNW22XX are optically-coupled logic gates. The HCPL‑22XX, and HCPL-02XX contain a Ga As P LED while the HCNW22XX contains an Al Ga As LED. The detectors have totem pole output stages and optical receiver input stages with built-in Schmitt triggers to provide logic-patible waveforms, eliminat ing the need for additional waveshaping. A superior internal shield on the HCPL-2211/12, HCPL0211, HCPL-2232 and HCNW2211 guarantees mon mode transient immunity of 10 k V/µs at a mon mode voltage of 1000 volts.
