74HCT138S16-13 from Diodes Incorporated, in a SO-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Address input 0 is the least significant binary select bit; the inputs have Schmitt trigger action and accept up to 6.0 V, and unused inputs should be held at VCC or ground. |
| 2 | A1 | input | Address input 1 selects the output along with A0 and A2; the inputs have Schmitt trigger action and accept up to 6.0 V, and unused inputs should be held at VCC or ground. |
| 3 | A2 | input | Address input 2 is the most significant binary select bit; the inputs have Schmitt trigger action and accept up to 6.0 V, and unused inputs should be held at VCC or ground. |
| 4 | E1 | input | Enable input 1 is active LOW; the device is enabled only when E1 and E2 are low and E3 is high. |
| 5 | E2 | input | Enable input 2 is active LOW; the device is enabled only when E1 and E2 are low and E3 is high. |
| 6 | E3 | input | Enable input 3 is active HIGH; the device is enabled only when E3 is high and E1 and E2 are low. |
| 7 | Y7 | output | Output 7 is active LOW, going low only when the device is enabled and address 7 is selected, and is otherwise high. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | Y6 | output | Output 6 is active LOW, going low only when the device is enabled and address 6 is selected, and is otherwise high. |
| 10 | Y5 | output | Output 5 is active LOW, going low only when the device is enabled and address 5 is selected, and is otherwise high. |
| 11 | Y4 | output | Output 4 is active LOW, going low only when the device is enabled and address 4 is selected, and is otherwise high. |
| 12 | Y3 | output | Output 3 is active LOW, going low only when the device is enabled and address 3 is selected, and is otherwise high. |
| 13 | Y2 | output | Output 2 is active LOW, going low only when the device is enabled and address 2 is selected, and is otherwise high. |
| 14 | Y1 | output | Output 1 is active LOW, going low only when the device is enabled and address 1 is selected, and is otherwise high. |
| 15 | Y0 | output | Output 0 is active LOW, going low only when the device is enabled and address 0 is selected, and is otherwise high. |
| 16 | VCC | power_in | Supply voltage with a recommended operating range of 4.5 V to 5.5 V (absolute maximum 7.0 V). |
