FEATURES  
DESCRIPTIO  
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  
from100mVbelowgroundto1.2Vbelowthesupplyvoltage.  
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.  
■
UltraFast: 4.5ns at 20mV Overdrive  
7ns at 5mV Overdrive  
■
Low Power: 4mA per Comparator  
■
Optimized for 3V and 5V Operation  
■
Pinout Optimized for High Speed Ease of Use  
■
Input Voltage Range Extends 100mV  
Below Negative Rail  
■
TTL/CMOS Compatible Rail-to-Rail Outputs  
■
Internal Hysteresis with Specified Limits  
■
Low Dynamic Current Drain; 15µA/(V-MHz),  
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.
