(ON3131)
Optoisolators
Overview
CNC1S101 is a DIL type 4-pin single-channel optoisolator which is housed in a small package.
The CNC1S101 has a number of good features, including high I/O isolation voltage and current transfer ratio (CTR), as well as high speed
response.
Applications
Switching power supply
Computer terminal equipment
System equipment, measuring equipment
Telephones, copier and vending machines
Televisions, VCRs, and other consumer electronics products
Medical equipment and phsical and chemical equipment
Signal transmission between circuits with different potentials and impedances
