The LT
1720/LT1721 are UltraFast
TM
dual/quad compara-
tors optimized for single supply operation, with a supply
voltage range of 2.7V to 6V. The input voltage range extends
from 100mV below ground to 1.2V below the supply voltage.
Internal hysteresis makes the LT1720/LT1721 easy to use
even with slow moving input signals. The rail-to-rail outputs
directly interface to TTL and CMOS. Alternatively, the sym-
metric output drive can be harnessed for analog applications
or for easy translation to other single supply logic levels.
The LT1720 is available in the 8-pin MSOP and SO packages;
three pins per comparator plus power and ground. The
LT1721 is available in the 16-pin SSOP and S packages.
The pinouts of the LT1720/LT1721 minimize parasitic effects
by placing the most sensitive inputs (inverting) away from the
outputs, shielded by the power rails. The LT1720/LT1721 are
ideal for systems where small size and low power are
paramount.
