Part Number: TMUX1574

Hi guys,

Customer is using TMUX1574, can you guys take a quick look at the schematic? is this back to back implementation ok?

    Brain,

    There isn’t anything wrong with cascading a passive FET switch but you will need to know that there will be twice the effect of on-state resistance and capacitance.   The TMUX1574 is a new device with great low capacitance performance so I don’t think it will be an issue for the low speed JTAG debug signals.  

    In the schematics you are operating with 1.8 V supply and signals which is within the recommended operating conditions.

    Thank you,

    Adam
