TXU0104: Controlling the direction of data transfer

Abhijit Khadilkar
Intellectual 295 points
Part Number: TXU0104
Other Parts Discussed in Thread: TXU0304, , TXU0204, SN74AVC4T234

Hi, Description (section 3) of part number in datasheet says that data transfer is possible from A to B or B to A in unidirectional manner. How to control whether data transfer happens from A to B or B to A?

Which voltage is it suggested to pull up the OE pin VCCA or VCCB? in my case one voltage will be 1.8V, other 3.3V.

Can i use this part in place of SN74AVC4T234ZWAR, by continuously asserting OE?

thanks, Abhijit

    That description was copied from the TXU0204/TXU0304. The TXU0104 has four channels from A to B, and zero channels from B to A.

    OE can be pulled to VCCA or VCCB or any higher voltage.

    This device can replace the SN74AVC4T234.
