TXB0104-Q1: Pin to pin alternate to TXB0104-Q1 voltage translator

Part Number: TXB0104-Q1
Other Parts Discussed in Thread: SN74AXC4T245, SN74AXC8T245-Q1

Hi team

We are facing lots of issues with the buffer TXB0104-Q1

1. Output signal of GPIO is giving sine waveform of 58MHz.

2. In some of the circuits the buffer is not able to drive the loads

I would like to know if you are having any pin-to-pin compatible and same footprint uni-directional buffer. I would like to replace all the TXB0104-Q1 buffers on my board.

    Hi Abhijit,

    TXB is weak driver for 20uA drive stength and cannot drive high cap or resistive loads.

    There is currently no P2P device to replace this since TXB belong to auto bidirectional device.
    what are the voltage nodes being translated? Do you need them to be auto qualified?

    I can suggest using the SN74AXC4T245 for 4 channel up to 3.6V translation. Else, there is SN74AXC8T245-Q1 also available.
