  • TMUX1574: TMUX1574 - Switching between two sim cards. Baseband provides power to both sim card, can mux handle pull down for floating signal pins?

    TI Thinks Resolved
    Part Number: TMUX1574 I'm considering using TMUX1574 to switch between two sim cards just like the illustration posted below. The GSM modem provides power to the SIM_VCC so both sim connectors will always be powered even when the mux is switched off…
