  • RE: TCA6416A: looking for I/O expander solution for SPI interface

    Resolved
    TI does not make general-purpose SPI expanders. I²C and SPI are not compatible. If you have only inputs or only outputs, then you can use shift registers (e.g., SN74HCS165, SN74HCS595); their serial interface is SPI compatible. Alternatively, use…

  • RE: TIC12400-Q1: Looking for an alternative with fewer features

    Hi Yan, To implement this using just logic, you would need an unpractical amount of gates (100>). I don't think there's a viable solution here that wouldn't involve using a microcontroller since you have 24 switches. My suggestion would be to…
