74154: 1-of-16 Data Distributor

This package may be used to provide a 1-low-out-of-16 output or may be used to send input data to one selected output of sixteen, the remaining fifteen staying high.

The output address is selected with the 1, 2, 4, and 8 select lines. For instance, 1 low, 2 high, 4 high, and 8 low selects output No. 6.

If Enable and Data Input are both low, the selected output address goes low.

If Enable is low, and a Logic Input is provided the Data input, the selected output address follows the Logic input.

Note that the functions of data selector and data distributor cannot be interchanged in TTL. This circuit accepts one input and routes it to sixteen outputs.
