HTCSEMI · Temperature Sensors · TO-92
HT18B20ARTZ from HTCSEMI, 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 | Common pin; all voltages are referenced to this pin. |
| 2 | DQ | bidirectional | 1-Wire data input/output; the bus is connected to the supply through a pull-up resistor (4.7 kΩ in the connection diagrams) and the pin can also supply parasite power. |
| 3 | VDD | power_in | Power supply pin; supply voltage UDD is 3.0 V to 5.5 V in external-supply mode. |
