Other Parts Discussed in Thread: TXB0104
dear TI guys,
my customer use txb0104 to occur the below issue:
the device is used as voltage level translator for spi interface,vcca=1.2v, vccb=3.3v, the spi frequency is 3 MHZ,when the 3.3v side input a signal,the waveform of the 1.2v side distort; the waveform as below
the yellow waveform is 3.3v level,the green waveform is 1.2v level.
the application schematic as below
can you tell why like this, follow the datasheet,the device can support 30Mhz signal,but my customer only use the 2MHZ signal.
