Why the TXU0304-Q1? Do you require automotive qualification?
Transmitting logic signals over S/FTP cables is certainly possible. But the twisted pairs are intended for differential signals; if you transmit two separate signals over a pair, they will…
I have no definite explanation why the device behaves the same as if OE were not high.
But you have four unidirectional signals. A unidirectional translator like the TXU0304-Q1 would be much simpler and more robust.

Part Number: LSF0108-Q1 Other Parts Discussed in Thread: TXU0304-Q1 Hi, how should I consider this components in the transmission line? I have an IC with series resistor and controlled 50ohms trace, then this shift level LSF0108-Q1 and the trace to the…
Hello Evan,
If you are using this for SPI, then I would recommend TXU0304-Q1 or the AXC4T774 like Clemens mentioned. You shouldn't use auto-direction sensing devices unless your application requires it.

Two TXB I/Os must no be connected to each other. The outputs on both sides of the TXB are always active, and one output is not strong enough to override the voltage of the other one.
For unidirectional signals, you should use a unidirectional translator…
Part Number: TXS0108E-Q1 Other Parts Discussed in Thread: TXU0304-Q1 Hi Team,
I would like to use TXS0108E-Q1 for voltage conversion of 5V⇔3V on SPI communication of 400kbps.
Is there any problem should be considered?
Beat Regards, Tom Liu
Part Number: SN74LVC1G126-Q1 Other Parts Discussed in Thread: TXU0304 , TXU0304-Q1 , TXS0104E Hi
I would like to know do you have suggestions on part number for conversion of SPI from 5V uC to SD Card(3.3V).
I found N74LVC1G126-Q1 but this is single…
Part Number: TXB0104-Q1 Other Parts Discussed in Thread: SN74AXC4T774-Q1 , TXU0304-Q1 I applied the 4-Bit Bidirectional Voltage-Level Translator TXB0104-Q1 to the SPI communication port, but there was an issue with the SPI speed. Data rate is marked as…
Using only the TXU0304-Q1 simplifies the BOM.
If you do want to separate these signals, you can use any combination of TXU devices, i.e., TXU0204-Q1 for U6, TXU0304-Q1 for U10, any any TXU for U12.
The TXB has many potential problems; see sections…
