Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1E | input | Active-LOW enable input for decoder 1; when it is HIGH, all outputs 1Y0 to 1Y3 are forced HIGH. |
| 2 | 1A0 | input | Address input bit 0 for decoder 1 (binary weight 1), which selects one of outputs 1Y0 to 1Y3. |
| 3 | 1A1 | input | Address input bit 1 for decoder 1 (binary weight 2), which selects one of outputs 1Y0 to 1Y3. |
| 4 | 1Y0 | output | Active-LOW mutually exclusive output 0 of decoder 1, LOW when nE is LOW and nA1 nA0 = 00. |
| 5 | 1Y1 | output | Active-LOW mutually exclusive output 1 of decoder 1, LOW when nE is LOW and nA1 nA0 = 01. |
| 6 | 1Y2 | output | Active-LOW mutually exclusive output 2 of decoder 1, LOW when nE is LOW and nA1 nA0 = 10. |
| 7 | 1Y3 | output | Active-LOW mutually exclusive output 3 of decoder 1, LOW when nE is LOW and nA1 nA0 = 11. |
| 8 | GND | power_in | Ground (0 V) reference for all voltages on the device. |
| 9 | 2Y3 | output | Active-LOW mutually exclusive output 3 of decoder 2, LOW when 2E is LOW and 2A1 2A0 = 11. |
| 10 | 2Y2 | output | Active-LOW mutually exclusive output 2 of decoder 2, LOW when 2E is LOW and 2A1 2A0 = 10. |
| 11 | 2Y1 | output | Active-LOW mutually exclusive output 1 of decoder 2, LOW when 2E is LOW and 2A1 2A0 = 01. |
| 12 | 2Y0 | output | Active-LOW mutually exclusive output 0 of decoder 2, LOW when 2E is LOW and 2A1 2A0 = 00. |
| 13 | 2A1 | input | Address input bit 1 for decoder 2 (binary weight 2), which selects one of outputs 2Y0 to 2Y3. |
| 14 | 2A0 | input | Address input bit 0 for decoder 2 (binary weight 1), which selects one of outputs 2Y0 to 2Y3. |
| 15 | 2E | input | Active-LOW enable input for decoder 2; when it is HIGH, all outputs 2Y0 to 2Y3 are forced HIGH. |
| 16 | VCC | power_in | Positive supply voltage; the 74HCT139 recommended range is 4.5 V to 5.5 V with respect to GND. |
