I am trying to implement a solution to mux a single JTAG programmer to 1 of 8 JTAG devices. Our application does not allow a traditional chain. My initial thought is using five TMUX1108 with the select lines in parallel. Any advise on whether these can handle the clock speed and SI of JTAG reliably? One of the primary desires is for physical select lines instead of sending SPI/I2C commands to change the channel.
