40ns, Low-Power, 3V/5V, Rail-to-Rail  
Single-Supply Comparators  
MAX9140/MAX9141/  
MAX9142/MAX9144  
General Description  
Features  
The 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.  
● Fast, 40ns Propagation Delay (10mV Overdrive)  
● Low Power  
• 150μA Supply Current Per Comparator (3V)  
● Optimized for 3V and 5V Applications  
● Rail-to-Rail Input Voltage Range  
● Low, 500μV Offset Voltage  
The input common-mode range of the devices extends  
beyond both power-supply rails. The outputs pull to within  
0.3V of either supply rail without external pullup circuitry,  
making 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.  
● Internal Hysteresis for Clean Switching  
● Outputs Swing 300mV of Power Rails  
● CMOS/TTL-Compatible Outputs  
● Output Latch (MAX9141 Only)  
● Shutdown Function (MAX9141 Only)  
● Available in SC70 and SOT23 Packages  
● AEC-Q100 Qualified (MAX9140AAXK/V+T Only)  
The devices are higher-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.  
Applications  
● Line Receivers  
● Battery-Powered Systems  
● Threshold Detectors/Discriminators  
● 3V/5V Systems  
● Zero-Crossing Detectors  
● Sampling Circuits
