ZHCSM12D September 2020 – August 2022 TMUX6219
PRODUCTION DATA
The TMUX6219 supports Fail-Safe Logic on the control input pins (EN and SEL) allowing for operation up to 36 V above ground, regardless of the state of the supply pins. This feature allows voltages on the control pins to be applied before the supply pin, 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 logic input pins of the TMUX6219 to be ramped to +36 V while VDD and VSS = 0 V. The logic control inputs are protected against positive faults of up to +36 V in powered-off condition, but do not offer protection against negative overvoltage conditions.
