The SY22401H is a digital isolator for digital applications with 9000VRMS isolation rating per UL1577, targeted for cost-sensitive applications. The device has reinforced isolation ratings according to VDE, CSA, TUV and IEC standards.
Each isolation channel has a logic input and output buffer separated by double capacitive silicon dioxide (SiO2) insulation barrier. The SY22401H has four isolation channels with three channels oriented in one direction and one isolation channel in the opposite direction, as required, for example, for isolating the signals of an SPI bus. The SY22401H includes data integrity check with fail-safe states. In the event of input power or signal loss, the default output is a logic high. See the Theory of Operation sections for further details. When used in conjunction with isolated power supplies, the SY22401H prevents high common-mode voltages present on general digital signals or an SPI data bus from damaging sensitive circuitry.
The SY22401H is available in a 16-pin SOP wide-body package.
