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 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: V
PU_ACTUAL
= V
PU_IDEAL
+ V
TRANSISTOR
.
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, 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癈. Standby current typically is 3礎(chǔ) at +125癈.
8) To minimize I
DDS
, DQ should be within the following ranges: GND d DQ d GND + 0.3V or
V
DD
0.3V d DQ d 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癈 with V
DD
= 5.5V.
