The CA-IS37xx devices are high-performance dual/triple/four/six-channel, unidirectional digital isolators with up to 5kV_RMS isolation rating, ±150 kV/μs typical CMTI and ultra-fast data rate(DC to 150Mbps), provide all possible unidirectional channel configurations to accommodate any digital I/O applications’ requirement. These 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.
