The CA-IS386x devices are high-performance six-channel, unidirectional digital isolators with up to 5.7kVRMS (widebody package) isolation rating and ultra-fast data rate. The CA-IS386x devices offer high electromagnetic immunity and low emissions at low power consumption while isolating different ground domains and blocking high-voltage/high current transients from sensitive or human interface circuitry. Each isolation channel has a logic input and output buffer separated by a capacitive silicon dioxide (SiO2) insulation barrier, the integrated Schmitt trigger on each input provides excellent noise immunity.
The CA-IS386x family offers all possible unidirectional channel configurations to accommodate any 6-channel design digital I/O applications, especially for the multiple SPI devices isolation. The CA-IS3860 features six channels transferring digital signals in one direction; The CA-IS3861 device has five forward and one reverse-direction channel; The CA-IS3862 device offers four forward and two reverse direction channels isolation; The CA-IS3863 provides further design flexibility with three channels in each direction. All devices of this family feature default outputs. When the input is either not powered or is open-circuit, the default output is low for devices with the suffix L and high for devices with the suffix H, see the Ordering Information for suffixes associated with each option.
