Part Number: TXS0108E
According to the datasheet, VCCA shall be <= VCCB. However, a recently designed board contains VCCA=3.3V and VCCB=1.8V.
Q1. What are the ramifications of connecting VCCA and the A side bus to 3.3V signals, while connecting VCCB and the B side bus to 1.8V signals?
Q2. Is there a chance that the B side will experience voltage levels higher than 1.8V?
Q3. Besides reducing the VCCA and A side bus signals from 3.3V to 1.8V or lower, what other temporary board mods can you recommend to test the functionality of the level translators under proper operating conditions given that the existing 1.8V signals are not 3.3V tolerant?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
