ELECTRICAL CHARACTERISTICS (continued)
(V+ = 2.7V to 5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 14)
Note 1:
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.
Note 2:
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).
Note 3:
VOS is defined as the center of the input-referred hysteresis zone (see Figure 1).
Note 4:
The polarity of IB reverses direction as VCM approaches either supply rail. See Typical Operating Characteristics for more
detail.
Note 5:
Specified over the full common-mode range (VCMR).
Note 6:
Applies to the MAX941 only when in shutdown mode. Specification is for current flowing into or out of the output pin for
VOUT driven to any voltage from V+ to GND.
Note 7:
Typical power dissipation specified with V+ = 3V; maximum with V+ = 5.5V.
Note 8:
Parameter is guaranteed by design and specified with VOD = 5mV and CLOAD = 15pF in parallel with 400A of sink or
source current. VOS is added to the overdrive voltage for low values of overdrive (see Figure 2).
Note 9:
Specified between any two channels in the MAX942/MAX944.
Note 10: Specified as the difference between tPD+ and tPD- for any one comparator.
Note 11: Applies to the MAX941 only for both
S

and
L

pins.
Note 12: Applies to the MAX941 only. Comparator is active with
L
A
T
C
H
pin driven high and is latched with

H
pin driven low
(see Figure 2).
Note 13: Applicable to the MAX941 only. Comparator is active with
S
H
D
N
pin driven high and is in shutdown with
S

D
N
pin driven
low. Shutdown disable time is the delay when
S

N
is driven high to the time the output is valid.
Note 14: The MAX941_UA and MAX942_UA are 100% production tested at TA = +25°C. Specifications over temperature are
guaranteed by design.
