Can the Si53340 be used as a generic data buffer, rather than as a clock buffer? I see it has AC specs down to DC (i.e. not stopping at 1 MHz Min F like the 5330x.) Its Any In - Any Out structure would be handy if so as a translator.
The Si53340 input does not have to be a clock signal and a data input would be fine. You're correct, it does make a good logic translator!
