Other Parts Discussed in Thread: LSF0108
Hi,
We have been TXB0108PWR bidirectional level translator in one of our design, the PDF file for the scheamtics is attached.
for ex. : the GPIO6_3P3 and GPIO7_3P3 are shorted and GPIO6 is set as input and GPIO7 is set as output, then the input GPIO6 is not able to track the changes in the GPIO7 output GPIO, the voltage at the shorted point is 1.6V.
so my doubt is, if the GPIO6 has a pull pu resistor of 4.7k to 1.8V, in this case the bidirectional buffer will give the output as 3.3V on the GPIO6_3P3 net.
and when GPIO7 is low the GPIO7_3P3 will be 0V.
so when i connect these two GPIO6_3P3 and GPIO7_3P3 lines what will happen?
will the auto direction detect properly which line is input and which is output, or will it cause a problem?
is there any possible solution to this problem?
Thanks,
