## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power grounding pin for the internal IC and LED drivers (Pin Function Description table). |
| 2 | DIN | input | Control data signal input; at VDD = 5.0 V the input high threshold is at least 0.65*VDD and the input low threshold is at most 0.3*VDD. |
| 3 | VDD | power_in | Logic supply pin; the working voltage range is +3.7 V to +5.5 V with a 5.0 V typical value. |
| 4 | DOUT | output | Control data signal output that forwards the reshaped data to the next cascaded device; the datasheet recommends a series protection resistor of about 500 ohm (R1/R2) on the signal lines. |
