TXS0108E: On the previous datasheet, themin VCCA was 1.2V, the reason for the change to 1.4V？

See TXS0108E: VCCA min changed to 1.4V.

Hi Seasat,

The post Clemens provided is accurate, but I wanted to give a little bit more information for you.

As work progressed on releasing a new package for this device (the NME package), data was collected under certain conditions that suggested marginal performance of the device for Vcca < 1.4V. It was determined upon further investigation that there could be limited cases where, if Vcca <1.4V, the device would not perform as expected. In order to best move forward with the datasheet as a guarantee of performance, it is best to reduce the operating range of the device to eliminate the possibility of device malfunction.

 This is an electrical specification change, however, there are no changes to the package composition or silicon used and therefore existing designs with VCCA > 1.4V will continue to operate as expected. For designs that exist where 1.2V < VCCA <1.4V, they may still continue to operate, however there is a limited risk that depending on how a particular device is processed, it may not meet the previous datasheet limit, and therefore operation of the device for VCCA <1.4V is a risk.
