PARAMETER
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. Minimum
allowable pullup resistance is slightly greater than the value necessary to produce the
absolute maximum current (20mA) during 1-Wire low times at V
