Hi. Not sure how to operate a TLC540I. What signal do i need to tell it to start sampling data? Also once data is sampled will it be at the output automatically or do i need another signal to enable the data out??

It's an interesting critter. It somewhat appears from the data sheet that once you have pulled chip select low and selected a multiplexer channel, using the I/O clock and the address input line, then the system clock will agitate the internals and do the conversion.

It also appears that the I/O clock will step the conversion out after chip select has gone high, but only after the conversion has taken place.

Page 9 of the data sheet is where the process gets explained.
