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.

Note 14:
Inferred from the 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.
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).
V
OS
is defined as the center of the input-referred hysteresis zone (see Figure 1).
The polarity of IB reverses direction as V
CM
approaches either supply rail. See
Typical Operating Characteristics
for more
detail.
Specified over the full common-mode range (V
CMR
).
Applies to the MAX941 only when in shutdown mode. Specification is for current flowing into or out of the output pin for
V
OUT
driven to any voltage from V+ to GND.
Typical power dissipation specified with V+ = 3V; maximum with V+ = 5.5V.
Parameter is guaranteed by design and specified with V
OD
= 5mV and C
LOAD
= 15pF in parallel with 400μA of sink or
source current. V
OS
is added to the overdrive voltage for low values of overdrive (see Figure 2).
Specified between any two channels in the MAX942/MAX944.
Specified as the difference between t
PD+
and t
PD-
for any one comparator.
Applies to the MAX941 only for both
SHDN
and
LATCH
pins.
Applies to the MAX941 only. Comparator is active with
LATCH
pin driven high and is latched with
LATCH
pin driven low
(see Figure 2).
Applicable to the MAX941 only. Comparator is active with
SHDN
pin driven high and is in shutdown with
SHDN
pin driven
low. Shutdown disable time is the delay when
SHDN
is driven high to the time the output is valid.
The MAX941_UA and MAX942_UA are 100% production tested at T
