Note 2: Full RPUP range guaranteed by design and simulation. not production tested. Production testing performed at a fixed RPUP value. 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: Capacitance on the data pin could be 800pF when VPUP is first applied. If a 2.2k W resistor is used to pull up the data line, 2.5µs after VPUP has been applied the parasite capacitance will not affect normal communications. Note 5: Guaranteed by design and simulation. Not production tested. Note 6: The voltage on IO needs to be less than or equal to VILMAX whenever the master drives the line low. Note 7: VTL and VTH are functions of the internal supply voltage, which is a function of VPUP and the 1-Wire Recovery Times. 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: After VTH is crossed during a rising edge on IO, the voltage on IO has to drop by at least VHY to be detected as logic '0'. 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: The earliest recognition of a negative edge is possible at tREH after VTH has been previously reached. Note 14: Highlighted numbers are NOT in compliance with legacy 1-Wire product standards. See comparison table below. Note 15: tPDH is deemed to have ended when the voltage on IO drops below 80% of VPUP on the leading edge of the presence-detect low pulse. tPDL is deemed to have begun when the voltage on IO drops below 20% of VPUP on the leading edge of the pulse. Note 16: Interval during the negative edge on IO at the beginning of a Presence Detect pulse between the time at which the voltage is 80% of VPUP and the time at which the voltage is 20% of VPUP. Note 17: e represents the time required for the pullup circuitry to pull the voltage on IO up from VIL to VTH. Note 18: d represents the time required for the pullup circuitry to pull the voltage on IO up from VIL to the input high threshold of the bus master. Note 19: Note 20: Note 21: The I-V characteristic is linear for voltages greater than 7V. tMSP is a system required sample point and not directly production tested. Production testing is performed on related parameters tPDH and tPDL. Parameter tFPD is guaranteed by design and simulation, not production tested. Production tested for VIHP(min). VIHP(max) is guaranteed by design and simulation, not production tested.
