System requirement.
Maximum allowable pullup resistance is a function of the number of 1-Wire devices in the system and 1-Wire recovery
times. The specified value here applies to systems with only one device and with the minimum 1-Wire recovery times. For
more heavily loaded systems, an active pullup such as that found in the DS2480B may be required.
Capacitance on the data pin could be 800pF when V PUP is first applied. If a 2.2k Ω resistor is used to pull up the data line,
2.5μs after V PUP has been applied, the parasite capacitance does not affect normal communications.
V TL and V TH are functions of the internal supply voltage, which is a function of V PUP and the 1-Wire recovery times. The
V TH and V TL maximum specifications are valid at V PUP = 5.25V. In any case, V TL < V TH < V PUP .
Voltage below which, during a falling edge on IO, a logic 0 is detected.
