DS28EA00U+T&R

Analog Devices Inc Maxim Integrated · Temperature Sensors · MSOP-8

DS28EA00U+T&R from Analog Devices Inc Maxim Integrated, in a MSOP-8. 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 and parasitic power supply; an open-drain pin that requires an external pullup resistor.
2 N.C. unconnected No connection.
3 N.C. unconnected No connection.
4 GND power_in Ground supply reference for the 1-Wire bus and device.
5 N.C. unconnected No connection.
6 PIOA (DONE) bidirectional Open-drain PIOA channel and chain output; for sequence detection it must connect to PIOB of the next device in the chain, and it is left open or connected to GND on the last device in the chain.
7 PIOB (EN) bidirectional Open-drain PIOB channel and chain input; for sequence detection, PIOB of the first device in the chain must be connected to GND.
8 VDD power_in Power supply input that must be connected to GND for operation in parasite-power mode; the datasheet specifies a supply range of 3.0 V to 5.5 V.
