NOTES:
1. All voltages are referenced to ground.
2. Measured with outputs open.
3. VPUP = external pullup voltage.
4. Input load is to ground.
5. An additional reset or communication sequence cannot begin until the reset high time has expired.
6. Read data setup time refers to the time the bus master must pull the I/O line low to read a bit. Data is
guaranteed to be valid within 1
ms of this falling edge.
7. Under certain low voltage conditions VIL1MAX may have to be reduced to as much as 0.5V to always
guarantee a Presence Pulse.
8. The reset low time (tRSTL) should be restricted to a maximum of 960
ms, to allow interrupt signaling,
otherwise, it could mask or conceal interrupt pulses.
9. When VBAT ramps up, the oscillator is always off.
10. At VBAT = 3V
± 10%
11. At VBAT = 5V
± 10%
12. VIH1 has to be VBAT -0.3V or higher.
13. The optimal sampling point for the master is as close as possible to the end time of the 15s tRDV
period without exceeding tRDV. For the case of a Read-One Time Slot, this maximizes the amount of
time for the pull-up resistor to recover to a high level. For a Read-Zero Time Slot, it ensures that a
read will occur before the fastest 1-Wire device(s) release the line.
14. The duration of the low pulse sent by the master should be a minimum of 1s with a maximum value
as short as possible to allow time for the pull-up resistor to recover the line to a high level before the
1-Wire device samples in the case of a Write-One Time or before the master samples in the case of a
Read-One Time.
