TXB0101: No cap for VCCB is placed on EVM

Part Number: TXB0101
Other Parts Discussed in Thread: TXS0101

Hello team,

TXB0101 and TXS0101 are similar device and bypass cap should be placed on both VCCA and VCCB. But bypass cap is placed on TXS0101EVM and not placed on TXB0101EVM.

Is TXB0101 wrong schematic? 

Best regards,
Koyo

  • Hello Koyo,

    There seems to be an error with the TXB EVM schematic in which VCCB and Input A are switched.

    If you look at the Board Layout for both TXS and TXU EVMs, VCCB (Pin 6) has a bypass capacitor. Apologies for the confusion.

    Regards,

    Josh
