## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power grounding pin for the device; the datasheet gives no separate electrical limit for this pin. |
| 2 | DIN | input | Control data signal input, with a high-level threshold of at least 0.65×VDD and a low-level threshold of at most 0.35×VDD at VDD = 5.0 V. |
| 3 | VDD | power_in | Power supply pin with a chip input voltage range of 3.7 V to 5.5 V. |
| 4 | DOUT | output | Control data signal output; the application circuit recommends a series protection resistor of about 500 Ω (R2) at the signal output, subject to actual test data. |
