| 16 CHANNEL TO 1 CHANNEL MULTIPLEXER. MODEL IBL-DE-1
|
| A Multiplexer (data selector) is the electronic version of a one-way rotary switch. A single-pole, sixteen - position rotary switch on the left. The sixteen inputs (0-15) are shown on the left, and a single output on the right is labeled Y. A data selector is shown on the right. The data at input 2 (a logical 1) is being transferred through the contacts of the rotary switch. Similarly, the data at input 2 (a logical 1) is being transferred through the circuitry of the data selector on the right. The data position is selected by mechanically turning the rotor on the rotary switch. The data position is selected in the data selector by placing the proper binary number on the data-select inputs (D, C, B, and A). The data selector permits data to flow only from input to output, whereas the rotary switch allows data to flow in both directions. A data selector can be thought of as being similar to a one ?way rotary switch. |
