This Tile can act either as either a sample-and-hold or track-and-hold depending on which input the clock is fed into.
The signal “to be sampled” should be put into the upper left jack, and the output taken from the upper right. To run the Tile as a sample-and-hold, run a clock into the bottom left S&H input. To use the Tile as a track-and-hold, run a clock into the bottom right T&H input. It is safe to run a clock or different clocks into each of the S&H and T&H inputs.
