The CA-IS376x devices are high-performance six-channel,  unidirectional digital isolators with up to 3.75kV_RMS (narrowbody package) or 5kV_RMS (wide-body package) isolation  rating and ultra-fast data rate. The CA-IS376x devices offer high electromagnetic immunity and low emissions at low  power consumption while isolating different ground  domains and block high-voltage/high-current transients  from sensitive or human interface circuitry. Each isolation  channel has a logic input and output buffer separated by  capacitive silicon dioxide (SiO₂) insulation barrier, the  integrated Schmitt trigger on each input provide excellent  noise immunity.  

The CA-IS376x family offers all possible unidirectional  channel configurations to accommodate any 6-channel  design digital I/O applications, especial for the multiple SPI  devices isolation. The CA-IS3760 features six channels transferring digital signals in one direction; The CA-IS3761 device has five forward and one reverse-direction channels;  The CA-IS3762 device offers four forward and two reversedirection channels isolation; The CA-IS3763 provides further  design flexibility with three channels in each direction. All  devices of this family features default outputs. When the  input is either not powered or is open-circuit, the default  output is low for devices with suffix L and high for devices  with suffix H, see the Ordering Information for suffixes  associated with each option.
