CS817x20HS Low-Power Dual-Channel Digital Isolators

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.The CS817x20/CS817x22 family of devices offers all possible unidirectional channel configurations to accommodate 2-channel design digital I/O applications.The CS817x20HS and CS817x20LS feature 2 channels transferring digital signals in one direction;

The CS817x22HS and CS817x22LS devices have one forward and one reverse-direction channel. 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 suffix LS and high for devices with suffix HS, see the Ordering Information for suffixes associated with each option.This family of digital isolators is based on a simple isolation architecture that provides a robust isolated data path and requires no special considerations or initialization at start up. A simplified block diagram for a single channel of the CS817x20 and CS817x22 is shown in the figure below. The CS817x20/CS817x22 family of devices are specified over the -40°C to +105°C operating temperature range and are available in 8-pin SOIC narrow body package.
