DC ELECTRICAL CHARACTERISTICS
(V
NOTES:
1) All voltages are referenced to ground.
2) The Pullup Supply Voltage specification assumes that the pullup device is ideal, and therefore the high level of
3) See typical performance curve in
4) Logic-low voltages are specified at a sink current of 4mA.
5) To guarantee a presence pulse under low voltage parasite power conditions, V
6) Logic-high voltages are specified at a source current of 1mA.
7) Standby current specified up to +70°C. Standby current typically is 3µA at +125°C.
8) To minimize I
9) Active current refers to supply current during active temperature conversions or EEPROM writes.
10) DQ line is high (“high-Z” state).
11) Drift data is based on a 1000-hour stress test at +125°C with V

PARAMETER
the pullup is equal to V
pullup transistor must include margin for the voltage drop across the transistor when it is turned on; thus:
