ADC3683: SPI Interface - Drive Current

Part Number: ADC3683
Other Parts Discussed in Thread: TXB0104,

Hi TI team,

I'm planning to connect the ADC3683's SPI interface to a 3.3V FPGA bank. I'm considering the use of the TXB0104 level shifter, which would be convenient for handling the biderectional SDIO pin. The level shifters datasheet asks for the following:

"the device driving the data I/Os of the TXB0104 device must have drive strength of at least ±2 mA"

In the ADC's datasheet, I can't find a spec for the IO pin's drive strength, only the test condition comment for the high/low level of +/- 400 uA. Am I missing something?

Hence the question - will those components be compatible?

Thanks,
Mike
