The CS817xXX family of ultra-low-power digital isolators used Chipanalog’s “Pulse-Coding” capacitive isolation technology, offering as low as 70μA per channel low quiescent current. These isolated CMOS compatible digital I/Os features up to 3kV_RMS isolation rating and ±150 kV/μs typical CMTI, providing 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 a capacitive silicon dioxide (SiO₂) insulation barrier, only requiring two V_DD_ bypass capacitors to build a digital signal isolation solution.
