HTCSEMI · Temperature Sensors · TO-92
HT18B20ATZ 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; it must be pulled up to UPU through an external resistor (4.7 kΩ in Figures 12 and 13), and UIL max is 0.8 V at UDD = 5 V. |
| 3 | VDD | power_in | Power supply pin with UDD range 3.0 V to 5.5 V; UDD is 0 V when the device is powered from the DQ pin in parasite mode. |
