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 V PU . In order to meet the V IH spec of the DS18S20, 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:
V PU_ACTUAL = V PU_IDEAL + V TRANSISTOR .
3) See typical performance curve in Figure 16 .
4) Logic-low voltages are specified at a sink current of 4mA.
5) To guarantee a presence pulse under low voltage parasite power conditions, V ILMAX 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 3 μ A at +125 ° C.
8) To minimize I DDS , DQ should be within the following ranges: GND ≤ DQ ≤ GND + 0.3V or
V DD – 0.3V ≤ DQ ≤ V DD .
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 V DD = 5.5V.
