Part Number: TXB0108

TXB0104QPWRQ1 level translator is failing to translate from low to high & vice versa when processor gpio pin is set to out(in/out),can you please help to resolve the issue.

 

Issue explained below:

 

When processor is set to out and gpio pin will be at high level(1.8V) which connects A side of level translator(VCCA=1.8V) and when low is passed from 3.3V devices through B side level translator(3.3V) its observed that the processor GPIO pin is still at high & failing to pull down to low by level translator, please help to resolve the issue.  

 

Thanks & Regards,

Satish
