PRODUCTION DATA
The TMUX113x devices support Fail-Safe Logic on the control input pins (SELx and EN) allowing for operation up to 5.5V, regardless of the state of the supply pins. This feature allows voltages on the control pins to be applied before the supply pins, protecting the device from potential damage. Fail-Safe Logic minimizes system complexity by removing the need for power supply sequencing on the logic control pins. For example, the Fail-Safe Logic feature allows the select pins of the TMUX113x devices to be ramped to 5.5V while VDD = 0V. Additionally, the feature enables operation of the TMUX113x devices with VDD = 1.2V while allowing the select pins to interface with a logic level of another device up to 5.5V.
