The LT1711 is 4.5ns comparator featuring rail-to-rail inputs, rail-to-rail complementary outputs and an output latch. Optimized for 3V and 5V power supplies, it operates over a single supply voltage range from 2.4V to 12V or from ±2.4V to ±6V dual supplies.The LT1711 is designed for ease of use in a variety of systems. In addition to the wide supply voltage flexibility, the rail-to-rail input common mode range extends 100mV beyond both supply rails, and the outputs are protected against phase reversal for inputs extending further beyond the rails. Also, the rail-to-rail inputs may be taken to opposite rails with no significant increase in input current. The rail-to-rail matched complementary outputs interface directly to TTL or CMOS logic and can sink 10mA to within 0.5V of GND or source 10mA to within 0.7V of V+.The LT1711 has an internal TTL/CMOS compatible latch for retaining data at the outputs. The latch holds data as long as the latch pin is held high. Latch pin hysteresis provides protection against slow moving or noisy latch signals. The LT1711 is available in the 8-pin MSOP package.ApplicationsHigh Speed Automatic Test EquipmentCurrent Sense for Switching RegulatorsCrystal Oscillator CircuitsHigh Speed Sampling CircuitsHigh Speed A/D ConvertersPulse Width ModulatorsWindow ComparatorsExtended Range V/F ConvertersFast Pulse Height/Width DiscriminatorsLine ReceiversHigh Speed Triggers

The LT1715 is an UltraFast™dual comparator optimized for low voltage operation. Separate supplies allow independent analog input ranges and output logic levels with no loss of performance. The input voltage range extends from 100mV below VEEto 1.2V below VCC.Internal hysteresis makes the LT1715 easy to use even with slow moving input signals. The rail-to-rail outputs directly interface to TTL and CMOS. The symmetric output drive results in similar rise and fall times that can be harnessed for analog applications or for easy translation to other single supply logic levels.The LT1715 is available in the 10-pin MSOP package. The pinout of the LT1715 minimizes parasitic effects by placing the most sensitive inputs away from the outputs, shielded by the power rails.For a dual/quad single supply comparator with similar propagation delay, see the LT1720/LT1721. For a single comparator with similar propagation delay,see the LT1719.ApplicationsHigh Speed Differential Line ReceiversLevel TranslatorsWindow ComparatorsCrystal Oscillator CircuitsThreshold Detectors/DiscriminatorsHigh Speed Sampling CircuitsDelay Lines

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
