Frequent questions
  • [FAQ]: What Multiplexers or Switches can I use for RS-232, RS-422, and RS-485 Applications?

    Nir Gilgur
    Nir Gilgur
    When trying to find a multiplexer as a solution for RS-232, RS-422, and RS-485 applications. It is important to understand what parameters to look for when trying to find the right mux. Each protocol has its own requirements, but in order to make it simple…

  • [FAQ] TMUXS7614D: What is a SPI Controlled MUX?

    Nir Gilgur
    Nir Gilgur
    Part Number: TMUXS7614D Tool/software: Most multiplexers use GPIO signals to switch between input and output connections. Another method of controlling a multiplexer is by using SPI. In place of GPIO control pins, a device controlled with SPI will…

  • [FAQ] What is Latch up in CMOS Devices and How can Latch up Immune Multiplexers Improve System Reliability?

    Kameron Hill
    Kameron Hill
    What is Latch up? Latch-Up is a condition where a low impedance path is created between a supply pin and ground. This condition is caused by a trigger (current injection or overvoltage), but once activated, the low impedance path remains even after…
