## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; the datasheet lists this pin as NC for the DCK package. |
| 2 | A | input | Logic input with a valid input range of 0 V to 3.6 V; unused inputs must be held at VCC or GND per the datasheet. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | output | Inverted logic output rated for ±20 mA continuous output current and ±8 mA drive at VCC = 1.65 V. |
| 5 | VCC | power_in | Positive supply; recommended operating range is 0.8 V to 2.7 V. |
