Dear team,
In my understanding, TXS0102 doesn't need the external pull up resistor. If the customer add the external resistor, they can get the larger drive capability, right? But the driver capability has a limit that is 10mA, so the external pullup resistor has a minimum limit. In below schematic, for A port, the current is 1.8/(3.3k//10k)=0.72mA; for B port, the current is 3.3/(3.3k//10k)=1.32mA. Both current are smaller than 10mA, so the pullup resistor is ok, right?
Thanks & Best Regards,
Sherry
