*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Absolute maximum limits apply
individually, not in combination. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.

The device must suffer no reliability degradation if any supply pin is either shorted
to ground or left floating for an indefinite periods of time during normal operation.

If either of the latch enables, LEA or LEB are low, the output
follows the input. If LEA or LEB are high, the comparator out-
puts will be latched and they won’t change.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD53042 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
