40ns, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators
General DescriptionThe MAX9140/MAX9141 are single and the MAX9142/
MAX9144 are dual/quad high-speed comparators opti-
mized for systems powered from a 3V or 5V supply. The
MAX9141 features latch enable and device shutdown.
These devices combine high speed, low power, and
Rail-to-Rail®inputs. Propagation delay is 40ns, while
supply current is only 150µA per comparator.
The input common-mode range of the MAX9140/
MAX9141/MAX9142/MAX9144 extends beyond both
power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, mak-
ing these devices ideal for interface with both CMOS
and TTL logic. All input and output pins can tolerate a
continuous short-circuit fault condition to either rail.
Internal hysteresis ensures clean output switching, even
with slow-moving input signals.
The MAX9140/MAX9141/MAX9142/MAX9144 are high-
er-speed, lower-power, and lower-cost upgrades to
industry-standard comparators MAX941/MAX942/
MAX944.
The MAX9140 are offered in tiny 5-pin SC70 and SOT23
packages. The MAX9141 and MAX9142 are available in
8-pin SOT23 and SO packages, while the MAX9144 is
available in both 14-pin SO and TSSOP packages.

at TA= +25°C.) (Note 1)
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.

ELECTRICAL CHARACTERISTICS (continued)(VCC= 5V, VCM= 0, SHDN= LE= VCC(MAX9141 only), CL = 15pF, TA= TMINto TMAX, unless otherwise noted. Typical values are
at TA= +25°C.) (Note 1)
Note 1:All devices are 100% production tested at TA= +25°C. Specifications over temperature are guaranteed by design.
Note 2:Inferred from PSRR test.
Note 3: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.
Note 4:VOSis defined as the center of the input-referred hysteresis zone. See Figure 1.
Note 5: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 6:The polarity of IBreverses direction as VCM approaches either supply rail.
Note 7:Specified over the full common-mode voltage range (VCMR).
Note 8:Specification is for current flowing into or out of the output pin for VOUTdriven to any voltage from VCCto GND while the part
is in shutdown.
Note 9:Specified between any two channels in the MAX9142/MAX9144.
Note 10:Specified as the difference between tPD+and tPD-for any one comparator.
Note 11:Applies to the MAX9141 only for both SHDNand LE.
Note 12:Applies to the MAX9141 only. Comparator is active with LEdriven high and is latched with LEdriven low (VOD= 10mV). See
Figure 2.
Note 13:Applicable to the MAX9141 only. Comparator is active with the SHDNdriven high and is shutdown with SHDNdriven low.
Shutdown enable time is the delay when the SHDNis driven high to the time the output is valid. Shutdown disable time is the
delay when the SHDNis driven low to the time the comparator shuts down.
