Six Channel Standard Digital Isolators
The CA-IS376x devices are high-performance six-channel, unidirectional digital isolators with up to 3.75kVRMS (narrowbody package) or 5kVRMS (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.
