CD74HCT139M96 from Texas Instruments, in a SOIC-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 | 1E | input | Active-low enable input for decoder 1; when high all four 1Y outputs stay high, and it serves as the data input in demultiplexer operation. |
| 2 | 1A0 | input | Select input A0 for decoder 1; with 1A1 selects which of the four 1Y outputs goes low. |
| 3 | 1A1 | input | Select input A1 for decoder 1; with 1A0 selects which of the four 1Y outputs goes low. |
| 4 | 1Y0 | output | Active-low output 0 of decoder 1, normally high; standard output drives 10 LSTTL loads. |
| 5 | 1Y1 | output | Active-low output 1 of decoder 1, normally high; standard output drives 10 LSTTL loads. |
| 6 | 1Y2 | output | Active-low output 2 of decoder 1, normally high; standard output drives 10 LSTTL loads. |
| 7 | 1Y3 | output | Active-low output 3 of decoder 1, normally high; standard output drives 10 LSTTL loads. |
| 8 | GND | power_in | Ground reference; DC VCC or ground current limited to ±50mA. |
| 9 | 2Y3 | output | Active-low output 3 of decoder 2, normally high; standard output drives 10 LSTTL loads. |
| 10 | 2Y2 | output | Active-low output 2 of decoder 2, normally high; standard output drives 10 LSTTL loads. |
| 11 | 2Y1 | output | Active-low output 1 of decoder 2, normally high; standard output drives 10 LSTTL loads. |
| 12 | 2Y0 | output | Active-low output 0 of decoder 2, normally high; standard output drives 10 LSTTL loads. |
| 13 | 2A1 | input | Select input A1 for decoder 2; with 2A0 selects which of the four 2Y outputs goes low. |
| 14 | 2A0 | input | Select input A0 for decoder 2; with 2A1 selects which of the four 2Y outputs goes low. |
| 15 | 2E | input | Active-low enable input for decoder 2; when high all four 2Y outputs stay high, and it serves as the data input in demultiplexer operation. |
| 16 | VCC | power_in | Positive supply; HCT types operate from 4.5V to 5.5V, absolute maximum -0.5V to 7V. |
