Pinout

Pin Name Type Function
1 Y0 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.
2 Y1 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.
3 Y2 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.
4 Y3 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.
5 Y4 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.
6 Y5 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.
7 Y6 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.
8 Y7 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.
9 Y8 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.
10 Y9 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.
11 Y10 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.
12 GND power_in Ground reference at 0 V for all voltages on the device.
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.
