The LT® 1719 is an UltraFastTM 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 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.
