DS18B20U+T&R from Analog Devices Inc Maxim Integrated, in a MSOP-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 | DQ | bidirectional | Open-drain 1-Wire interface providing bidirectional data communication and parasite power capability, operating at 3.0V to 5.5V with input logic-low threshold VIL = -0.3 to +0.8V and logic-high threshold VIH = +2.2 to VDD+0.3V. |
| 2 | N.C. | unconnected | No connection; leave unconnected on printed circuit board. |
| 3 | N.C. | unconnected | No connection; leave unconnected on printed circuit board. |
| 4 | GND | power_in | Ground reference establishing 0V baseline for all voltage measurements. |
| 5 | N.C. | unconnected | No connection; leave unconnected on printed circuit board. |
| 6 | N.C. | unconnected | No connection; leave unconnected on printed circuit board. |
| 7 | N.C. | unconnected | No connection; leave unconnected on printed circuit board. |
| 8 | VDD | power_in | Optional external power supply input accepting 3.0V to 5.5V; must be connected to ground to enable parasite power mode using internal charge pump powered from DQ pin. |
