XL3483 from XINLUDA, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output; it is driven HIGH when the receiver inputs are left open (fail-safe), and the receiver is enabled by a logic LOW on RE (pin 2). |
| 2 | RE | input | Active-LOW receiver output enable; a logic LOW enables the receiver and a logic HIGH disables it, and RE high with DE low puts the device into shutdown (supply current typically 1µA, 10µA maximum). |
| 3 | DE | input | Active-HIGH driver output enable; a logic HIGH enables the differential driver outputs and a logic LOW forces them into high impedance (high-Z). |
| 4 | DI | input | Driver input that sets the state of the differential driver outputs A and B when DE is HIGH. |
| 5 | GND | power_in | Ground connection for the device. |
| 6 | A | bidirectional | Non-inverting driver output and receiver input; receiver input common-mode range is -7V to +12V. |
| 7 | B | bidirectional | Inverting driver output and receiver input; receiver input common-mode range is -7V to +12V. |
| 8 | VCC | power_in | Positive supply, specified at 3.3V ±5% for normal operation, with an absolute maximum of 6.0V. |
