Description

General part information

LT1719 Series

The LT1719 is an UltraFast™comparator optimized for low voltage operation. The input voltage range extends from 100mV below VEEto 1.2V below VCC. 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.ApplicationsHigh Speed Differential Line ReceiverCrystal Oscillator CircuitsLevel TranslatorsThreshold Detectors/DiscriminatorsZero-Crossing DetectorsHigh Speed Sampling CircuitsDelay Lines
