TMUXHS4212: About RSVD1/2 pin connection

Part Number: TMUXHS4212

In datasheet version MAY 2020 , RSVD1/2 can be left open, but in latest datasheet version MAY 2022, the RSVD1/2 need to be connected to VCC.

Is there any problem if RSVD1/2 are left floating for the new TMUXHS4212 chip?

  • Hi Wendy,

    We've seen issues where this MUX will stop switching after a certain number of switches when these pins are left open. Please connect both RSVD pins to Vcc for normal operation.

    Best,

    Shane
