7.3.4 Powered-off Protection

Powered-off protection up to 3.6V on the signal path of the TMUX1511 provides isolation when the supply voltage is removed (VDD = 0V). When the TMUX1511 is powered-off, the I/Os of the device remain in a high-Z state. Powered-off protection minimizes system complexity by removing the need for power supply sequencing on the signal path. The device performance remains within the leakage performance mentioned in the Electrical Specifications. For more information on powered-off protection refer to Eliminate Power Sequencing with Powered-off Protection Signal Switches
