Note 1:
All voltages are referenced to ground.

Note 2:
V

power supply.
Note 3:
V
PUP
= external pullup voltage.
Note 4:
Input load is to ground.
Note 5:
Capacitance on the data line could be 800pF when power is first applied. If a 5k

resistor is used
Note 6:
Guaranteed by design, not production tested.
Note 7:
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 s of this falling edge, and remains valid for 14 s minimum.
(15 s total from falling edge on 1-Wire bus.)
Note 8:
An additional reset or communication sequence cannot begin until the reset high time has
expired.
Note 9:
The reset low time (t
RSTL
) should be restricted to a maximum of 960 s, to allow interrupt
signaling; otherwise it could mask or conceal interrupt pulses.
