The TMUX13xx-Q1 family offers protection against injection current events across a wide operating supply range (1.62 V to 5.5 V). These devices include 1.8 V logic compatible control input pins that enable operation in systems with 1.8 V I/O rails. Additionally, the control input pins support Fail-Safe Logic which allows for operation up to 5.5 V, regardless of the state of the supply pin. This feature stops the logic pins from back-powering the supply rail while the injection current circuitry prevents the signal path from back-powering the supply. These features make the TMUX13xx-Q1 a family of general purpose multiplexers and switches that can reduce system complexity, board size, and overall system cost.
