Note:
*²⁾ fall time right after start-up depends on the load used and can be as long as 10ms
*³⁾ this is the maximum start-up time of the IC itself; this parameter does not reflect performance of a sensor; during start-up the
output is inactive (off) regardless of the state of the NO/NC pin
*⁴⁾ for more information on capacitive loads refer to Overload Explanation in Section 5.7.
