Note 1.
Stresses listed as the above
“
Absolute Maximum Ratings
”
may cause permanent damage to the device. These are
for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2.
Devices are ESD sensitive. Handling precaution recommended.
Note 3.
The device is not guaranteed to function outside its operating conditions.
Note 4.
θ
JA
is measured in the natural convection at T
A
= 25
°
C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard.
Note 5.
The voltage V
OL
can be calculated by V
OL
= V
DD
Ir * R. Where R is the pull-up resistor and Ir is the current flowing
through the pull-up resistor. For typical application (R=100k
Ω
), V
OL
is less than 0.2V.
