Separate supplies allow flexible operation to accomodate separate analog input ranges and output logic levels. The input voltage range extends from 100mV below VEE to 1.2V below VCC. Internal hysteresis makes Alternatively the symmetric output drive can be harnessed for analog applications or for easy translation to other single supply logic levels. For a dual/quad comparator with similar performance, see the LT1720/LT1721. , LTC and LT are registered trademarks of Linear Technology Corporation.
