The 100355 contains four transparent latches, each of which can accept and store data from two sources. When both Enable (E#_n) inputs are LOW, the data that appears at an output is controlled by the Select (S_n) inputs, as shown in the Operating Mode table. In addition to routing data from either D₀ or D₁, the Select inputs can force the outputs LOW for the case where the latch is transparent (both Enables are LOW) and can steer a HIGH signal from either D₀ or D₁ to an output. The Select inputs can be tied together for applications requiring only that data be steered from either D₀ or D₁. A positive-going signal on either Enable input latches the outputs. A HIGH signal on the Master Reset (MR) input overrides all the other inputs and forces the Q outputs LOW. All inputs have 50 k Ohm pulldown resistors.
