DS28E07+T

Analog Devices Inc Maxim Integrated · EEPROM · TO-92-3

DS28E07+T from Analog Devices Inc 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 1-Wire protocol requires only a single data lead and a ground return.
2 IO bidirectional 1-Wire bus interface; the open-drain signal requires an external pullup resistor.
3 N.C. unconnected Not connected.
