The LT1719 is an UltraFast comparator optimized for low
voltage operation. The input voltage range extends from
100mV below VEE to 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 exible operation, accomodating separate analog
input ranges and output logic levels.
For a dual/quad comparator with similar performance, see
the LT1720/LT1721.
