DS18B20Z+T&R from Analog Devices Inc Maxim Integrated, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N.C. | unconnected | No connection. Leave floating or tie as convenient; not internally bonded. |
| 2 | N.C. | unconnected | No connection. Leave floating or tie as convenient; not internally bonded. |
| 3 | VDD | power_in | Optional supply voltage input, +3.0V to +5.5V for local-power operation. In parasite-power mode, VDD MUST be tied to GND; power is then derived from the DQ line via an external ~4.7kΩ pullup. |
| 4 | DQ | bidirectional | 1-Wire data input/output. Open-drain pin requiring an external ~4.7kΩ pullup to VPU (3.0-5.5V). Also provides power to the device in parasite-power mode. Standby current typ 750nA; active current 1-1.5mA at VDD=5V. |
| 5 | GND | power_in | Ground reference (0V). |
| 6 | N.C. | unconnected | No connection. Leave floating or tie as convenient; not internally bonded. |
| 7 | N.C. | unconnected | No connection. Leave floating or tie as convenient; not internally bonded. |
| 8 | N.C. | unconnected | No connection. Leave floating or tie as convenient; not internally bonded. |
