  • 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 V 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 overcoming space constraints.
    The TS33x are specified for temperatures between -40 °C to +125 °C, making them ideal for a wide range of applications.

    Key Features

    • Supply operation from 1.6 V to 5 V
    • Low current consumption: 20 μA
    • Rail-to-rail inputs
    • Wide temperature range: -40 °C to +125 °C
    • Low output saturation voltage
    • Low propagation delay: 210 ns
    • Open-drain output
    • ESD tolerance: 2 kV HBM/200 V MM
    • SMD packages
    • Automotive qualified
