NOTES:
1. All voltages are referenced to ground.
2. VPUP = external pull-up voltage.
3. Input load is to ground.
4. An additional reset or communication sequence cannot begin until the reset high time has expired.
5. Read data setup time refers to the time the host must pull the 1-Wire bus low to read a bit. Data is
guaranteed to be valid within 1
μs of this falling edge.
6. VIH is a function of the external pull-up resistor and VPUP .
7. 30 nanocoulombs per 72 time slots @ 5.0V.
8. At VCC =5.0V with a 5 kΩ pull-up to VCC and a maximum time slot of 120 μs.
9. Capacitance on the data pin could be 800 pF when power is first applied. If a 5 k
Ω resistor is used to
pull up the data line to VCC , 5 μs after power has been applied the parasite capacitance will not affect
normal communications.
10. Under certain low voltage conditions VILMAX may have to be reduced to as much as 0.5V to always
guarantee a presence pulse.
