Note 1: All voltages are referenced to ground.

Note 4: Input load is to ground.

Note 5: Capacitance on the data line could be 800pF when power is first applied. If a 5k

W resistor is used

ms after power has been applied, the parasite capacitance does

not affect normal communications.

Note 6: Guaranteed by design, not production tested.

Note 7: 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

ms of this falling edge, and remains valid for 14ms minimum.

(15

ms total from falling edge on 1-Wire bus.)

Note 8: An additional reset or communication sequence cannot begin until the reset high time has

expired.

ms, to allow interrupt

signaling; otherwise it could mask or conceal interrupt pulses.
