TXB0104-Q1: OE low with outputs at high impedance

Hey Frank,

Frank QIN said:

May I know the reason of why "When the output-enable (OE) input is low, all outputs are placed in the high-impedance state." ?

Its an active High enable pin.

Frank QIN said:

Which part is the +/- 2mA in 8.3.2 driving?

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

Frank QIN said:

Is this 4kOhm a real resistor or a equivalent resistance?

It is a real resistor.
