NOTES:
1.
All voltages are referenced to ground.
2.
V
PUP
= external pullup 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.
6.
Capacitance on the data contact could be 800 pF when power is first applied. If a 5 k
resistor is used
to pullup the data line to V
CC
, 5 ms after power has been applied, the parasite capacitance will not
affect normal communications.
7.
The reset low time (t
RSTL
) should be restricted to a maximum of 960 μs, to allow interrupt signaling,
otherwise, it could mask or conceal interrupt pulses.
8.
V
IH
is a function of the external pullup resistor and the V
CC
power supply.
