NOTES:
1. All voltages are referenced to ground.
2. V
PUP
= external pull–up voltage.
3. Input load is to ground.
4. An additional reset or communication sequence cannot begin until the reset high time has expired.
5. 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.)
6. V
IH
is a function of the external pull–up resistor and the V
CC
supply.
7. 30 nanocoulombs per 72 time slots @ 5.0V.
8. At V
CC
=5.0V with a 5 k
pull–up to V
CC
and a maximum time slot of 120
μ
s.
9. Capacitance on the data pin could be 800 pF when power is first applied. If a 5 k
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 communica-
tions.
10.Maximum 1–Wire voltage for programming parameters is 11.5V to 12.0V; temperature range is –40
°
C to +50
°
C.
11. Under certain low voltage conditions V
ILMAX
may have to be reduced to as much as 0.5V to always guarantee
a presence pulse.
12.The accumulative duration of the programming pulses for each address must not exceed 5 ms.
