DS18B20U-HXY from HXY MOSFET, in a MSOP-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 | DQ | bidirectional | Open-drain one-wire bus communication port that needs an external pull-up (about 5 kΩ per the datasheet) and also supplies the device in parasitic power mode. |
| 2 | NC | unconnected | No internal connection; leave floating (悬空). |
| 3 | NC | unconnected | No internal connection; leave floating (悬空). |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | NC | unconnected | No internal connection; leave floating (悬空). |
| 6 | NC | unconnected | No internal connection; leave floating (悬空). |
| 7 | NC | unconnected | No internal connection; leave floating (悬空). |
| 8 | VDD | power_in | Supply pin, 2.7 V to 5.5 V per the DC characteristics; must be tied to GND when the device runs in parasitic power mode. |
