描述 Description

The HCPL-22XX, HCPL-02XX, and HCNW22XX are optically coupled logic gates. The HCPL-22XX, and HCPL-02XX contain a GaAsP LED while the HCNW22XX contains an AlGaAs LED. The detectors have totempole output stages and optical receiver input stages with built-in Schmitt triggers to provide logic compatible waveforms, eliminat ing the need for additional waveshaping.
