I saw multiple e2e thread that the output current driving strength of TXB0104 is +/-20uA. I'd like to ask several questions regarding this spec.
1. I believe that +/-20uA is only a guaranteed value by TI but actually TXB0104 may be able to drive more current. Is it correct?
2. I guess the positive current indicates the current flow from the external device into TXB0104 and the negative current indicates the current flow from the TXB0104 to the external devices. Is it correct?
3. In datasheet, Continuous output current is indicated -50 to 50 mA. Could you help me to understand the huge discrepancy between +/-50mA and +/-20uA?
