| 13 | Y11 | output | Active-LOW decoded data output; it is driven LOW when its address on A0 to A3 is selected while E0 and E1 are both LOW, and stays HIGH otherwise. |
| 14 | Y12 | output | Active-LOW decoded data output; it is driven LOW when its address on A0 to A3 is selected while E0 and E1 are both LOW, and stays HIGH otherwise. |
| 15 | Y13 | output | Active-LOW decoded data output; it is driven LOW when its address on A0 to A3 is selected while E0 and E1 are both LOW, and stays HIGH otherwise. |
| 16 | Y14 | output | Active-LOW decoded data output; it is driven LOW when its address on A0 to A3 is selected while E0 and E1 are both LOW, and stays HIGH otherwise. |
| 17 | Y15 | output | Active-LOW decoded data output; it is driven LOW when its address on A0 to A3 is selected while E0 and E1 are both LOW, and stays HIGH otherwise. |
| 18 | E0 | input | Active-LOW enable input; a HIGH on either E0 or E1 forces all outputs HIGH, and it can serve as the data input when the device is used as a demultiplexer. |
| 19 | E1 | input | Active-LOW enable input; a HIGH on either E0 or E1 forces all outputs HIGH, and it can serve as the data input when the device is used as a demultiplexer. |
| 20 | A3 | input | Binary-weighted address input that selects one of the sixteen outputs Y0 to Y15. |
| 21 | A2 | input | Binary-weighted address input that selects one of the sixteen outputs Y0 to Y15. |
| 22 | A1 | input | Binary-weighted address input that selects one of the sixteen outputs Y0 to Y15. |
| 23 | A0 | input | Binary-weighted address input that selects one of the sixteen outputs Y0 to Y15. |
| 24 | VCC | power_in | Supply voltage; the recommended operating range is 2.0 V to 6.0 V with 5.0 V typical. |
