This device can be used in a Standard-mode I
be met. This device does not stretch SCL Low time. It outputs the next data bit to the SDA line within
t
before the SCL line is released.
As a transmitter, the device provides internal minimum delay time t
region (min. 300 ns) of the falling edge of SCL t
conditions.
For V
biased and consumes 100 µA (typical) until the sensor POR resets and acknowledges a shutdown com-
mand.
As a receiver, SDA should not be sampled at the falling edge of SCL. SDA can transition t
