It is not clear what the status of the TVS1401 is. The data sheet shows a PTVS1401 as active and the TVS1401 a preview. But, I cannot find the PTVS1401 in the TI system and no vendor has the TVS1401.
If the TVS1401 is in development stage, I need to know if/when it will be released. If the PTVS1401 exists, I need to know what vendors carry it. Right now, I have to remove it from my design.
