TYPICAL APPLICATION
DESCRIPTION
Dual/Quad, 4.5ns, Single
Supply 3V/5V Comparators
with Rail-to-Rail Outputs
The LT
1720/LT1721 are UltraFastTM 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 volt-
age. 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 symmetric output drive can be harnessed for analog
applications or for easy translation to other single supply
logic levels.
The LT1720 is available in three 8-pin packages; three pins
per comparator plus power and ground. In addition to SO
and MSOP packages, a 3mm
× 3mm low prole (0.8mm)
dual ne pitch leadless package (DFN) is available for space
limited applications. 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.
