7.3.4 Power-off Protection

The TMUX2889 has powered-off protection up to ±5.5V on the switch path. This keeps the switch in a high impedance mode and isolates the source (Sx) and drain (Dx) pins when the supply is removed (Vdd = 0 V). 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.
