Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | input | Address input, bit 0 (least significant bit) of the 2-bit select code that chooses which active-low output goes low. |
| 2 | B | input | Address input, bit 1 (most significant bit) of the 2-bit select code that chooses which active-low output goes low. |
| 3 | Y3 | output | Output 3, active low; goes low when B is high and A is high. |
| 4 | GND | power_in | Ground pin. |
| 5 | Y2 | output | Output 2, active low; goes low when B is high and A is low. |
| 6 | Y1 | output | Output 1, active low; goes low when B is low and A is high. |
| 7 | Y0 | output | Output 0, active low; goes low when B is low and A is low. |
| 8 | VCC | power_in | Supply pin; operating range is 1.65 V to 5.5 V per the Recommended Operating Conditions. |
