* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

FUNCTIONAL DESCRIPTION
The IL75XX series is the set of voltage detectors equipped with a high stability voltage reference which is connected
to the negative input of a comparator denoted as V
REF
in block diagram.
When the voltage drop to the positive input of the comparator (V
B
) is high than V
REF
, V
OUT
goes high. If V
CC
is
decreased so that V
B
falls to a value less than V
REF
, the comparator output inverts from high to low, V
OUT
goes low. The
device has hysteresis to prevent the circuit from oscillation when V
B
V
REF
. If V
CC
falls below the minimum operating
voltage, the output becomes undefined. The detectable voltage is defined as:
VDET
