Description
The TS331, TS332 and TS334 are single, dual and quad micropower and low-voltage comparators. They can operate with a supply voltage ranging from 1.6 to 5 V with a typical current consumption as low as 20 μA. In addition, rail-to-rail inputs make them a perfect choice for low-voltage applications.
Their availability in tiny packages is a real advantage for space saving constraints.
The TS33x are specified for a wide temperature range of -40°C to +125°C, making them ideal for a wide range of applications.

VMachine model (MM)
1. All voltage values, except differential voltage, are referenced to Vcc-.
2. Short-circuits can cause excessive heating. These values are typical.
3. 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.
4. 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.
5. 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.
