Hello,
I am using the SN74LVC3G34 buffer to connect an SPI bus to a RAM.
What I am observing is that the buffer output signals decrease over time, which causes the RAM to fail when processing the data. I have tried different SPI speeds (from 5kHz to 30MHz) and also tried disconnecting the RAM at the output but the results are the same.
This is the schematic:
And this is the SPI clock signal at the input (green) and at the output (pink) of the buffer:
What could be the problem?
Thank you.
