Chipanalog CS817x22HS Digital Isolator

Chipanalog CS817x22HS

The CS817x20/CS817x22 family of ultra-low-power digital isolators used Chipanalog’s “Pulse-Coding” capacitive isolation technology, offering as low as 90μA per channel low quiescent current. These isolated CMOS compatible digital I/Os feature up to 3kVRMS isolation rating and ±150 kV/μs typical CMTI, provide high electromagnetic immunity and low EMI. All device versions have Schmitt trigger inputs for high noise immunity and each isolation; channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, only require two VDD_ bypass capacitors to build a digital signal isolation solution.
