## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Address input 0 of the three-bit binary-weighted address that selects which output goes active low. |
| 2 | A1 | input | Address input 1 of the three-bit binary-weighted address that selects which output goes active low. |
| 3 | A2 | input | Address input 2 of the three-bit binary-weighted address that selects which output goes active low. |
| 4 | E1 | input | Enable input 1, active LOW; the enable state requires E1 and E2 asserted low and E3 asserted high, otherwise all outputs are high. |
| 5 | E2 | input | Enable input 2, active LOW; the enable state requires E1 and E2 asserted low and E3 asserted high, otherwise all outputs are high. |
| 6 | E3 | input | Enable input 3, active HIGH; the enable state requires E3 asserted high together with E1 and E2 asserted low. |
| 7 | Y7 | output | Output 7, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 8 | GND | power_in | Ground reference for the device; unused inputs should be held at VCC or Ground. |
| 9 | Y6 | output | Output 6, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 10 | Y5 | output | Output 5, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 11 | Y4 | output | Output 4, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 12 | Y3 | output | Output 3, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 13 | Y2 | output | Output 2, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 14 | Y1 | output | Output 1, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 15 | Y0 | output | Output 0, active LOW; it stays high when the device is disabled or when it is not the addressed output. |
| 16 | VCC | power_in | Supply voltage, recommended range 2.0 V to 6.0 V, with absolute maximum rating of -0.5 V to +7.0 V. |
