Hi

could you check whether one TI_ISO6741DWR can drive 5pcs 90E36A SPI bus.  (except CS)

    Hi Gareth,

    Thanks for reaching out.

    ISO6741 can drive multiple input pins provided the overall capacitive load on its output is <100pF. I checked M90E36A electrical specifications in datasheet but I couldn't find input capacitance of pins SCLK and SDI. If [capacitance(SCLK + SDI) * 5] <100pF, then ISO6741 should be able to drive without any issues. Thanks.
