NOTES:
1. All voltages are referenced to ground.
2. The Pullup Supply Voltage specification assumes that the pullup device (resistor or transistor) is
ideal, and therefore the high level of the pullup is equal to V PU . In order to meet the V IH spec of the
DS1822-PAR, the actual supply rail for the strong pullup transistor must include margin for the
voltage drop across the transistor when it is turned on; thus: V PU_ACTUAL = V PU_IDEAL + V TRANSISTOR .
3. See typical performance curve in Figure 15.
4. Logic low voltages are specified at a sink current of 4mA.
5. To always guarantee a presence pulse under low voltage parasite power conditions, V ILMAX may have
to be reduced to as low as 0.5V.
6. Logic high voltages are specified at a source current of 1mA.
7. Active current refers to supply current during active temperature conversions or EEPROM writes.
8. DQ line is high (“high-Z” state).
9. Drift data is based on a 1000 hour stress test at +125°C.
