## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive power supply pin; supply input voltage 3.5-7.5V (5V typical). |
| 2 | DOUT | output | Signal data output that forwards the reshaped data to the next cascaded device after 24 bits are received. |
| 3 | GND | power_in | Ground connection. |
| 4 | DIN | input | Signal data input; logic input voltage range -0.5 to 5.5V, high level at least 0.7VDD. |
