The LMV331 is designed to operate in the
temperature range of -40°C to +85°C. It is then
suitable for a large variety of applications.
Description
The LMV331 is a single and low voltage version of
industry standard LM339 and LM393. It can
operate with a supply voltage ranging from 2.7 to
5 V, and exhibits a lower current consumption
than its predecessors LM339 and LM393. This
device is a perfect choice for low-voltage
applications.
The device is available in both SOT23-5 and
SC70-5 packages, making it ideal for applications
where space saving is a constraint. The SC70-5
package is approximately half the size of the
SOT23-5.

1. All voltage values, except differential voltage, are referenced to Vcc-.
2. The magnitude of input and output voltages must never exceed the supply rail 0.3 V.
3. Short-circuits can cause excessive heating. These values are typical.
4. 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.
5. 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.
6. 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.
