The LT
廬
1719 is an UltraFast
TM
comparator optimized for low
voltage operation. Separate supplies allow flexible operation
to accomodate separate analog input ranges and output logic
levels. 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.
The LT1719 is available in the 8-pin SO package; a shutdown
control allows for reduced power consumption and extended
battery life in portable applications.
For a dual/quad comparator with similar performance, see
the LT1720/LT1721.
