Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EA | input | Enable input for decoder A; per the function table, EA LOW enables the decoder and EA HIGH forces outputs O0A to O3A HIGH. |
| 2 | A0A | input | Address input A0 for decoder A, selecting which of outputs O0A to O3A goes LOW together with A1A. |
| 3 | A1A | input | Address input A1 for decoder A, selecting which of outputs O0A to O3A goes LOW together with A0A. |
| 4 | O0A | output | Active-LOW output 0 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 00. |
| 5 | O1A | output | Active-LOW output 1 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 01. |
| 6 | O2A | output | Active-LOW output 2 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 10. |
| 7 | O3A | output | Active-LOW output 3 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 11. |
| 8 | VSS | power_in | Ground supply voltage, the 0 V reference for all voltages on the device. |
| 9 | O3B | output | Active-LOW output 3 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 11. |
| 10 | O2B | output | Active-LOW output 2 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 10. |
| 11 | O1B | output | Active-LOW output 1 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 01. |
| 12 | O0B | output | Active-LOW output 0 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 00. |
| 13 | A1B | input | Address input A1 for decoder B, selecting which of outputs O0B to O3B goes LOW together with A0B. |
| 14 | A0B | input | Address input A0 for decoder B, selecting which of outputs O0B to O3B goes LOW together with A1B. |
| 15 | EB | input | Enable input for decoder B; per the function table, EB LOW enables the decoder and EB HIGH forces outputs O0B to O3B HIGH. |
| 16 | VDD | power_in | Supply voltage, recommended range 3 V to 15 V referenced to VSS (absolute maximum +18 V). |
