General-Purpose, Low-Voltage,  
Single/Dual/Quad, Tiny-Pack Comparators  
General Description  
Features  
The LMX331/LMX393/LMX339 single/dual/quad com-  
parators are drop-in, pin-for-pin-compatible replace-  
ments for the LMV331/LMV393/LMV339. The LMX331H/  
LMX393H/LMX339H offer the performance of the  
LMX331/LMX393/LMX339 with the added benefit of inter-  
nal hysteresis to provide noise immunity, preventing out-  
put oscillations even with slow-moving input signals.  
o Guaranteed 1.8V to 5.5V Performance  
o -40°C to +125°C Automotive Temperature Range  
o Low Supply Current (60µA/Comparator at  
V
DD  
= 5.0V)  
o Input Common-Mode Voltage Range Includes  
Ground  
Advantages of the LMX331/LMX393/LMX339 series  
include low supply voltage, small package, and low cost.  
The LMX331 is available in both 5-pin SC70 and SOT23  
packages, LMX393 is available in both 8-pin µMAX and  
smaller SOT23 packages, and the LMX339 is available in  
14-pin TSSOP and SO packages. They are manufac-  
tured using advanced submicron CMOS technology.  
Designed with the most modern techniques, the  
LMX331/LMX393/LMX339 achieve superior performance  
over BiCMOS or bipolar versions on the market.  
o No Phase Reversal for Overdriven Inputs  
o Low Output Saturation Voltage (100mV)  
o Internal 2mV Hysteresis  
(LMX331H/LMX393H/LMX339H)  
o 5-Pin SC70 Space-Saving Package  
(2.0mm 2.1mm 1.0mm)  
(LMX331/LMX331H)  
The LMX331/LMX393/LMX339 offer performance  
advantages such as wider supply voltage range, wider  
operating temperature range, better CMRR and PSRR,  
improved response time characteristics, reduced off-  
set, reduced output saturation voltage, reduced input  
bias current, and improved RF immunity.
