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

.
3. See typical performance curve in Figure 16
4. Logic low voltages are specified at a sink current of 4 mA.
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 1 mA.
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

9. Active current refers to supply current during active temperature conversions or EEPROM writes.
10. DQ line is high (“hi-Z” state).
11. Drift data is based on a 1000 hour stress test at 125°C with V
DD
= 5.5V.
