Other Parts Discussed in Thread: TXB0104-Q1, TXB0104

Dear,

I am using TXB0104-Q1 device between Microcontroller to one slave device (SPI interface).

TXB0104 acting as a voltage transceiver. In B side 3.3V and A side 1.8V.

OE pin is connected to microcontroller port.

I am setting the OE pin as HIGH and trasmit some SPI data from micro to slave. But i am not getting the proper output at the B side of transceiver(TXB0104 ).

Could you please help here what i am doing wrong?

Small correction : But i am not getting the proper output at the A side of transceiver(TXB0104 ).

Please show the schematic of your circuit.

It's likely that the load on the output is too high; the TXB does not work with pull-up/-down resistors, or with long traces that add capacitance.

Hi Sakthi,

Please share a schematic and preferably some oscilloscope captures of the issue you are seeing.
