  • [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…
