Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | D3 | input | Data input 3, selected when select inputs C B A = L H H. |
| 2 | D2 | input | Data input 2, selected when select inputs C B A = L H L. |
| 3 | D1 | input | Data input 1, selected when select inputs C B A = L L H. |
| 4 | D0 | input | Data input 0, selected when select inputs C B A = L L L. |
| 5 | Y | output | Non-inverting multiplexer output; goes low when strobe is high. |
| 6 | W | output | Inverting multiplexer output; goes high when strobe is high. |
| 7 | ST | input | Active-low strobe input; low transfers selected data to outputs, high forces Y low and W high regardless of data or select inputs. |
| 8 | GND | power_in | Ground, 0 V reference. |
| 9 | C | input | Select address input C (most significant bit) of the three-bit data selector. |
| 10 | B | input | Select address input B of the three-bit data selector. |
| 11 | A | input | Select address input A (least significant bit) of the three-bit data selector. |
| 12 | D7 | input | Data input 7, selected when select inputs C B A = H H H. |
| 13 | D6 | input | Data input 6, selected when select inputs C B A = H H L. |
| 14 | D5 | input | Data input 5, selected when select inputs C B A = H L H. |
| 15 | D4 | input | Data input 4, selected when select inputs C B A = H L L. |
| 16 | VCC | power_in | Supply voltage, operating range 2.0 to 6.0 V (absolute maximum -0.5 to 7.0 V). |
