TXU0304: SPI clock speed and I2S data integrity

Part Number: TXU0304
Other Parts Discussed in Thread: SN74AXC4T774

Dear Designer:

1. I want to use TXU0304 as a 1.8v to 3.3v voltage level converter between 1.8v SOC and 3.3v SPI flash. The SPI flash will run at 104MHz. Is this feasible?

2. I want to use TXU0304 as a 1.8v to 3.3v voltage level converter between 1.8v SOC and 3.3v I2S audio codec. Will the Schmitt trigger function of TXU0304 input reduce or affect the accuracy of data transmission? (I2S MCLK around 50MHz)

Best Regards.

James Chen
