Tool/software:
Hey Team,
In the circuit we utilized for one of our industrial sensor read kits, we incorporated a TXB device as a bidirectional buffer. According to the datasheet, we can use pull-up or pull-down resistors greater than 50K, so we’ve implemented a 100K pull-up on the SEL_LINE pin.
Now, when the switch is in the OFF position, we're not observing any voltage on the "SEL_LINE" or "SEL_LINE_OUT" pins. Given that we have a pull-up in place, we would expect to see a 3.3V output, right? What's happening here? Is there any internal Pull up or Pull down on TS3DDr device?
1. Seeing this on multiple Boards
2. No assembly issue
