General purpose low voltage comparator
December 2011 Doc ID 16866 Rev 3 1/17
LMV331, LMV393, LMV339General-purpose low voltage comparators
Features Supply operation from 2.7 to 5V Low current consumption: 20 μA Input common mode range includes ground Wide temperature range: -40°C to +85°C Low output saturation voltage Propagation delay: 200ns Open drain output ESD tolerance: 2 kV HBM / 200 V MM SMD packages
Applications Mobile phones Notebooks and PDAs Battery supplied electronics General-purpose portable devices General-purpose low voltage applications
DescriptionThe LMV331, LMV393 and LMV339 are the
single/dual/quad and low voltage versions of the
industry standard LM339 and LM393. They can
operate with a supply voltage ranging from 2.7 to V , and exhibit a lower current consumption than
their predecessors LM339 and LM393. These
devices are a perfect choice for low-voltage
applications.
The LMV3xx are available in tiny packages,
making them ideal for applications where space
saving is a constraint.
The devices are designed to operate in the
temperature range of -40°C to +85°C and are
suitable for a variety of applications.

LMV331, LMV393, LMV339 Absolute maximum ratings and operating conditionsDoc ID 16866 Rev 3 3/17
Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings All voltage values, except the differential voltage, are referenced to Vcc-. Short-circuits can cause excessive heating. These values are typical. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating. Charged device model: all pins and package are charged together to the specified voltage and then
discharged directly to ground through only one pin. This is done for all pins.
