NOTES:
1.
Temperature conversion will work with ±2°C accuracy down to V
PUP
= 3.4V.
2.
All voltages are referenced to ground.
3.
I
DD
specified with low impedance pull up to 5.0V.
4.
Active current refers to temperature conversion.
5.
Writing to EEPROM consumes approximately 200
μ
A.
6.
t
RSTL
may be up to 4800
μ
s. With longer times, the result of temperature conversion may get lost.
7.
The reset low time should be restricted to a maximum of 960 ms, to allow interrupt signaling,
otherwise it could mask or conceal interrupt pulses.
8.
Read data setup time refers to the time the host must pull the 1-Wire bus low to read a bit. Data is
guaranteed to be valid within 1
μ
s of this falling edge and will remain valid for 14
μ
s minimum. (15
μ
s total from falling edge on 1-Wire bus.)
9.
Capacitance on the data contact could be 800 pF when power is first applied. If a 5k
resistor is used
to pull up the data line to V
CC
, 5
μ
s after power has been applied, the parasite capacitance will not
affect normal communications.
10.
Under certain low voltage conditions V
ILMAX
may have to be reduced to as much as 0.5V to always
guarantee a presence pulse.
11.
See Typical Curve for specification limits outside the 0°C to 70°C range. Thermometer error reflects
sensor accuracy as tested during calibration.
