TXB0104-Q1: OE low with outputs at high impedance

Frank QIN
Expert 7870 points
Part Number: TXB0104-Q1

Hi experts,

  1. May I know the reason of why "When the output-enable (OE) input is low, all outputs are placed in the high-impedance state." ?
  2. Which part is the +/- 2mA in 8.3.2 driving?
  3. Is this 4kOhm a real resistor or a equivalent resistance?

    Its an active High enable pin.

    The current required to over drive that inverter in series with the 4kohm to change the state of the I/O.

    It is a real resistor.
