Optoisolators
Overview
CNC7S101 is an AC input compatible optoisolator in which two GaAs high output infrared light emitting diode chips are connected in reverse parallel as light emitting elements, and opitically are connected to a high sensitivity Si phototransistor chip as a light detecting element in a small DIL 4-pin package. This optoisolator series also includes the two-channel CNZ3182, the three-channel CNC7T101, and the four-channel CNC1H101. The CNC7S101 series has a number of excellent features, including high I/O isolation voltage and current transfer ratio (CTR), as well as high speed response and high reliability.
