Optoisolators
Overview
CNC1S101 is a DIL type 4-pin single-channel optoisolator which
is housed in a small package. This optoisolator series also includes
the two-channel CNZ3132, the three-channel CNZ3133, and the four-
channel 3134.
The CNC1S101 series has a number of good features, including high I/
O isolation voltage and current transfer ratio (CTR), as well as high
speed response.
