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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

All devices are 100% production tested at T
A
= +25°C. Specifications over temperature are guaranteed by design.
Inferred from PSRR test.
Inferred from CMRR test. Note also that either or both inputs can be driven to the absolute maximum limit (0.3V beyond
either supply rail) without damage or false output inversion.
V
OS
is defined as the center of the input-referred hysteresis zone. See Figure 1.
The input-referred trip points are the extremities of the differential input voltage required to make the comparator output
change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis
zone. See Figure 1.
The polarity of I
B
reverses direction as V
CM
approaches either supply rail.
Specified over the full common-mode voltage range (V
CMR
).
Specification is for current flowing into or out of the output pin for V
OUT
driven to any voltage from V
CC
to GND while the part
is in shutdown.
Specified between any two channels in the MAX9142/MAX9144.
Specified as the difference between t
PD+
and t
PD-
for any one comparator.
Applies to the MAX9141 only for both
SHDN
and
LE.
Applies to the MAX9141 only. Comparator is active with
LE
driven high and is latched with
LE
driven low (V
OD
= 10mV). See
Figure 2.
Applicable to the MAX9141 only. Comparator is active with the
SHDN
driven high and is shutdown with
SHDN
driven low.
Shutdown enable time is the delay when the
SHDN
is driven high to the time the output is valid. Shutdown disable time is the
delay when the
SHDN
is driven low to the time the comparator shuts down.
