| LMV331 General-purpose low voltage comparator Features Supply operation from 2.7 to 5 V Low current consumption: 20 A Input common mode range includes ground Wide temperature range: -40C to +85C Low output saturation voltage Propagation delay: 200 ns Open drain output ESD tolerance: 2 kV HBM/200 V MM SMD packages: SC70-5 and SOT23-5 IN + LMV331 SOT23-5/SC70-5 Pin connections (top view) Applications 1 + - 5 VCC + Mobile phones Notebooks and PDAs Battery supplied electronics General-purpose portable devices General-purpose low voltage applications VCC - 2 IN 3 4 OUT 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. The LMV331 is designed to operate in the temperature range of -40C to +85C. It is then suitable for a large variety of applications.

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 k 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 ). 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. Table 2.
