Hi,
I am using TXB0108, few things need to check with the expert here. VCCA is 1.8V and VCCB is 3.3V
1) Do I need to put any pull up resistor at both side data input?
2) I encounter some issue when I pull up (51kohm) both port A and B to relative VDD as initial stage, then manually touch the data to a low (ground), both input and output (VDDB data) will always LOW and will not recover. Why will this happen?
Need your advice. Thank you very much!
Best regards,
KH
