The LT1719 is an UltraFast^™ comparator optimized for low voltage operation. The input voltage range extends from 100mV below V_EE to 1.2V below V_CC. Internal hysteresis makes the LT1719 easy to use even with slow moving input signals. The rail-to-rail outputs directly interface to TTL and CMOS. Alternatively the symmetric output drive can be harnessed for analog applications or for easy translation to other single supply logic levels. A shutdown control allows for reduced power consumption and extended battery life in portable applications.

The LT1719 is available in the SO-8 and 6-lead SOT-23 package. The SO-8 package has separate supplies which allow flexible operation, accomodating separate analog input ranges and output logic levels.

For a dual/quad comparator with similar performance, see the LT1720/LT1721.
