  • TCA9546A: TCA9546APWR

    Answer Suggested
    Part Number: TCA9546A Hello . I have two TCA9546APWR chips. The silk screen information is "PW546A 9AK G4 A6CR" and "PW546A 92K G4 A42W". What do these information (except PW546A, G4) mean? If possible, can you tell me the rules for these encodings?…

    Part Number: TCA9546A Hi TI Team, We are using TCA9546A IC in our project. As mentioned in datasheet A0,A1 and A2 are hardware configurable. Is it ok to keep them floating and what will be the default state of these signals.? What will happen if those…

  • TCA9546A: Do we have solution for MIPI MUX switch

    Part Number: TCA9546A Hi team, My customer already used this device for I2C MUX switch application. But they also need MIPI MUX switch. So do we have solution for them? Thanks

  • RE: TCA9546A: TCA9546A ibis file doesn't have series model

    Resolved
    Hi Klaus, The model would effectively just show the RDS(on) of the internal FET switch, so depending on the load current (a function of the pull-up resistances and pull-down driver strength) the switch will result in some voltage drop. (The voltage drop…
