NOTES:
1.
All voltages are referenced to ground.
2.
Logic one voltages are specified at a source current of 1 mA.
3.
Logic zero voltages are specified at a sink current of 4 mA.
4.
Active current refers to either temperature conversion or writing to the E
2
memory. Writing to E
2
memory consumes approximately 200
μ
A for up to 10 ms.
5.
Input load is to ground.
6.
Standby current specified up to 70
°
C. Standby current typically is 3
μ
A at 125
°
C.
7.
To always guarantee a presence pulse under low voltage parasite power conditions, V
ILMAX
may have
to be reduced to as much as 0.5V.
8.
To minimize I
DDS
, DQ should be: GND
≤
DQ
≤
GND +0.3V or V

9.
Under parasite power, the max t
RSTL
before a power on reset occurs is 960
