M16_1E is a 16-to-1 multiplexer with enable. When the enable input (E) is High, the M16_1E multiplexer chooses one data bit from 16 sources (D15 - D0) under the control of the select inputs (S3 - S0). The output (O) reflects the state of the selected input as shown in the truth table. When E is Low, the output is Low.
