Other Parts Discussed in Thread: TXS0108E

I am using on my board with ST translator ST2378EBJR .

Is the "TXS018EZXYR" can be a replacement?

From TI recommendation is "P"

If I turn the part so pin to pin can functionality as ST device can its work?

What a bout PU/PD output compare to ST2378?

What a bout the data rates compare to ST2378?

We are using a lot of kind customer application in the field, so we need to be compatible to ST2378E!!!!!!!!

Looking at the ST data sheet I see no reason for compatibility issues. Yes, our TXS0108 will work in the same applications as the ST device.

What a bout PU/PD output compare to ST2378?

I could not find the ST internal pull-up values on their data sheet. Our R pua and R pub have a value of 40 kΩ when the output is driving low. R pua and R pub have a value of 4 kΩ when the output is driving high

What a bout the data rates compare to ST2378?

For the TXS0108 -

Max Data Rates

– 60 Mbps (Push Pull)

– 2 Mbps (Open Drain)

Please explain the status of 2 Mbps (open drain).

Does TXS0108EZXYR working at open drain?

Open Drain describes the device driving the TXS0108E.

If the device driving the TXS has an open drain driver the speed will be 2Mbps.

If the device driving the TXS uses a push-pull driver, the max datarate will be higher.

Thanks ,

I still waiting for the answer about package issue pin to pin competblity compare to ST

TI TXS0108EZXYR (ZXY Package ) >>>>>>>>>> Pin A1 is VCCA

ST ST2378EBJR (Package-Flip-Chip 20)>>>>>>Pin A1 is I/O VL8

Identification pin is close to A1 !!!!!!!!

It does look like if you turn the part around, the pinout is compatible.

You may want to double check this.

Yes,double check this issue.

Mean, as I understand on my design with TI replacement need to turn around.

And the pin corner on my PCB design (A1) won’t compatibly.

Also is different:

ST VOLC (low level output i/ovcc >>>>>>>>>IO=1.0mA

TI VOLB @VCCA=3V >>>>>>>>>>>>>>>>>IOL=0.4mA

Please explain.
