DS28E07+

Maxim Integrated · Pre-ordered Chips · TO-92-3

DS28E07+ from Maxim Integrated, in a TO-92-3. 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 return for the 1-Wire bus, the only reference connection required besides the single IO line.
2 IO bidirectional 1-Wire bus interface; the open-drain signal requires an external pullup resistor.
3 N.C. unconnected Not connected; this pin has no electrical function in the TO-92 package.
