Txb0108 and txs0108 level conversion chip problem consultation
1. How to deal with the redundant channels of txb0108? Is there any risk in hanging? What about txs0108?
2. The OE is directly connected to the vcca without the pull-down resistor. After the vccb vcca is powered on, it is found that the external IO (voltage equal to vcca) will leak to the OE and a side signal pins of the chip. What is the reason?
