The DS1867-100 can operate from -40°C to +85°C, but it's recommended to operate within -20°C to +70°C for optimal performance.
To ensure reliable communication, make sure to use a pull-up resistor on the 1-Wire bus, keep the bus length short (<100m), and use a dedicated 1-Wire bus master or a microcontroller with a built-in 1-Wire interface.
No, the DS1867-100 is designed to operate from 2.7V to 5.5V, but it's not recommended to use it with a 5V power supply as it may exceed the maximum rating. Use a 3.3V or 3V power supply for optimal performance.
In parasite power mode, the DS1867-100 derives power from the 1-Wire bus. To handle this mode, ensure the bus master or microcontroller provides a strong pull-up on the 1-Wire bus and use a capacitor (typically 100nF) to decouple the power pin from the bus.
The typical current consumption of the DS1867-100 is around 1mA during active operation, but it can be as low as 1μA in standby mode.
