NOTES:

1. V_PP– ∆V

must be within 11.5 to 12.0V.

PROG

2. Applies only if a 12.0V supply is connected. If V and V are tied together, current is less than 1 µA.

3. Input load is to GND.

4. Voltage difference between V and 1–W.

5. Voltage difference between V and 1–W.

6. 8.68 µs (115.2 kbps), 52 µs (19.2 kbps), 17.36 µs (57.6 kbps), 104 µs (9.6 kbps).

7. Nominal values; tolerance = ±5%.

8. At V = 5.0V and 100 pF load to GND.

9. See Table 7, Function and Speed Matrix.

10.Independent of baud rate.

11. Minimum at 115.2 kbps, maximum at 9.6 kbps.

12.The master reset cycle is complete after t

is over.

13.Minimum value at Overdrive speed; maximum value at regular speed.

14.∆ is the time to complete the activity on the 1–Wire bus; values range from 0 (configuration command) up to

5130 µs (alarming presence pulse)
