74LV138PW from Nexperia, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Address input 0 (LSB) for selecting one of eight outputs. |
| 2 | A1 | input | Address input 1 for selecting one of eight outputs. |
| 3 | A2 | input | Address input 2 (MSB) for selecting one of eight outputs. |
| 4 | E1 | input | Enable input 1, active-LOW. All Y outputs are HIGH when E1 is HIGH. |
| 5 | E2 | input | Enable input 2, active-LOW. All Y outputs are HIGH when E2 is HIGH. |
| 6 | E3 | input | Enable input 3, active-HIGH. All Y outputs are HIGH when E3 is LOW. |
| 7 | Y7 | output | Active-LOW decoded output 7 (selected when A2:A0 = 111 and device enabled). |
| 8 | GND | power_in | Ground reference (0 V). |
| 9 | Y6 | output | Active-LOW decoded output 6 (selected when A2:A0 = 110 and device enabled). |
| 10 | Y5 | output | Active-LOW decoded output 5 (selected when A2:A0 = 101 and device enabled). |
| 11 | Y4 | output | Active-LOW decoded output 4 (selected when A2:A0 = 100 and device enabled). |
| 12 | Y3 | output | Active-LOW decoded output 3 (selected when A2:A0 = 011 and device enabled). |
| 13 | Y2 | output | Active-LOW decoded output 2 (selected when A2:A0 = 010 and device enabled). |
| 14 | Y1 | output | Active-LOW decoded output 1 (selected when A2:A0 = 001 and device enabled). |
| 15 | Y0 | output | Active-LOW decoded output 0 (selected when A2:A0 = 000 and device enabled). |
| 16 | VCC | power_in | Supply voltage, 1.0 V to 5.5 V operating range. |
