NOTES:

1. All voltages are referenced to ground.

2. Measured with both 3.3VIN and 5VIN =2.7V.

3. Measured with both 3.3VIN and 5VIN [=2.7V.

4. PBRST is internally pulled up to VIN(MAX) input with an internal impedance of approximately 40 kΩ.

5. Measured with either 3.3VIN or 5VIN =2.7V (valid for DS1834 and DS1834D only).

6. Measured with outputs open and both 3.3VIN and 5VIN [=5.5V.

7. Measured with outputs open and both 3.3VIN and 5VIN [=3.6V.

8. Noise immunity - pulses < 2 µs @ VCCTP minimum will not generate a reset.

9. tR =5 µs.
