LT1720/LT1721  
Dual/Quad, 4.5ns, Single  
Supply 3V/5V Comparators  
with Rail-to-Rail Outputs  
DESCRIPTION  
The LT®1720/LT1721 are UltraFastTM dual/quad compara-  
tors optimized for single supply operation, with a supply  
voltagerangeof2.7Vto6V.Theinputvoltagerangeextends  
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.  
FEATURES

Low Dynamic Current Drain; 15μA/(V-MHz),  
Dominated by Load In Most Circuits  
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 profile (0.8mm)  
dualfinepitchleadlesspackage(DFN)isavailableforspace  
limited applications. The LT1721 is available in the 16-pin  
SSOP and S packages.

APPLICATIONS  
n
High Speed Differential Line Receiver  
n
Crystal Oscillator Circuits  
n
Window Comparators  
Threshold Detectors/Discriminators  
Pulse Stretchers  
Zero-Crossing Detectors  
High Speed Sampling Circuits  
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.
