Note 1:

System requirement.

Note 2:

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 DS2482-x00, DS2480B, or DS2490 may be required.

Note 3:

The I-V characteristic is linear for voltages greater than 10V.

Note 4:

Note 5:

Guaranteed by design and simulation. Not production tested.

Note 6:

Note 7:

Note 8:

Voltage below which, during a falling edge on IO, a logic 0 is detected.

Note 9:

Voltage above which, during a rising edge on IO, a logic 1 is detected.

Note 10:

Note 11:

The I-V characteristic is linear for voltages less than 1V.

Note 12:

Applies to a single DS2413 attached to a 1-Wire line.

Note 13:

Note 14:

Highlighted numbers are NOT in compliance with legacy 1-Wire product standards. See comparison table below.

Note 17:

ε in Figure 12 represents the time required for the pullup circuitry to pull the voltage on IO up from V

Note 18:

δ in Figure 12 represents the time required for the pullup circuitry to pull the voltage on IO up from V

Note 19:

The I-V characteristic is linear for voltages greater than 7V.
