GXCAS · Temperature Sensors · TO-92
GX18B20 from GXCAS, in a TO-92. 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 | GND | power_in | Ground pin for the device. |
| 2 | DQ | bidirectional | Data input/output and open-drain 1-Wire interface pin; it also supplies power to the device in parasite power mode. |
| 3 | VDD | power_in | Optional supply pin; VDD must be grounded for operation in parasite power mode, and the supply voltage range is 2.5V to 5.5V. |
