TMUX1574: Voltage applied to EN or SEL before power (VDD) is applied

Part Number: TMUX1574

Hi Team,

Is there a negative consequence or latch up condition that could occur is voltage is applied to EN/SEL pins before VDD has power?

Thanks,

Jared

    Hi Jared,

    No problem applying the EN/SEL voltage prior to VDD being set. This device has fail-safe logic which means the device can ramp its logic pin voltage independently of the supply voltage to help simplify power sequencing.

    Let me know if you have any other questions.

    Thanks!
