ZHCSIX6B October 2018 – Sept 2019 TMUX1574
Common applications that require the features of the TMUX1574 include multiplexing various protocols from a possessor or MCU such as SPI, JTAG, or standard GPIO signals. The TMUX1574 provides superior isolation performance when the device is powered. The added benefit of powered-off protection allows a system to minimize complexity by eliminating the need for power sequencing in hot-swap and live insertion applications. The example shown in Figure 42 illustrates the use of the TMUX1574 to multiplex an SPI bus to multiple flash memory devices.
