TXB0102DCUT ripple spec

Other Parts Discussed in Thread: TXB0102

Is there any ripple noise spec of TXB0102 for Vcc pin?

The datasheet only shows the Vcc range or tolerance, like +/- 0.1V or +/-0.15V).

How much the noise can be accepted? (how many mVpp).

Is there any regulation for that or don't care about the ripple noise?

The application is VccA: 3.3 V and VccB: 5V.

    Hi

    The electrical specifications are guaranteed for that tolerance of the supply as noted.

    Any noise ripple coming in from a supply to the vcca/vccb will be addressed by the decoupling capacitor. If there is additional noise, we might need to add more capaciotrs.  Do you have a concern on the noise coming in from the supply?  Thanks
