DS28E05R+T

Analog Devices Inc Maxim Integrated · EEPROM · SOT-23-3

DS28E05R+T from Analog Devices Inc Maxim Integrated, in a SOT-23-3. 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 IO bidirectional 1-Wire bus interface: open-drain signal that requires an external pullup resistor (max 1.5kΩ at 3.3V VPUP, max 750Ω at 1.8V VPUP per the datasheet).
2 N.C. unconnected Not connected.
3 GND power_in Ground reference for the 1-Wire bus and device.
