Hi,

My customer have a question about the VCCA and VCCB of TXS0206.

They referred to a following description in DS P.13 of TXS0108E.

During operation, ensure that VCCA ≤ VCCB at all times. During power-up sequencing, VCCA ≥ VCCB does not
damage the device, so any power supply can be ramped up first.

Do it also apply to TXS0206 and all TXS siries? There is no this description in TXS0206 DS.

Hi,

For TXS010X serial devices, VCCB will be more than VCCA when device is at normal operation mode. Thus, 'VCCB can be less VCCA' is added in power-up sequence comments.

But for TXS0206, both voltage supply range is from 1.2 to 3.6. Thus, either supply can ramp first.

Thanks
