NOTES:
1) All voltages are referenced to ground.
2) The Pullup Supply Voltage specification assumes that the pullup device is ideal, and therefore the
high level of the pullup is equal to VPU. In order to meet the VIH spec of the DS18B20, the actual
supply rail for the strong pullup transistor must include margin for the voltage drop across the
transistor when it is turned on; thus: VPU_ACTUAL = VPU_IDEAL + VTRANSISTOR.
3) See typical performance curve in Figure 17.
4) Logic-low voltages are specified at a sink current of 4mA.
5) To guarantee a presence pulse under low voltage parasite power conditions, VILMAX may have to be
reduced to as low as 0.5V.
6) Logic-high voltages are specified at a source current of 1mA.
7) Standby current specified up to +70
°C. Standby current typically is 3A at +125°C.
8) To minimize IDDS, DQ should be within the following ranges: GND ≤ DQ ≤ GND + 0.3V or
VDD – 0.3V ≤ DQ ≤ VDD.
9) Active current refers to supply current during active temperature conversions or EEPROM writes.
10) DQ line is high (“high-Z” state).
11) Drift data is based on a 1000-hour stress test at +125°C with VDD = 5.5V.
