FEATURES  
DESCRIPTIO  
Ultrafast: 4.5ns at 20mV Overdrive  
The LT®1711/LT1712 are UltraFastTM 4.5ns comparators  
featuringrail-to-railinputs,rail-to-railcomplementaryout-  
puts and an output latch. Optimized for 3V and 5V power  
supplies, they operate over a single supply voltage range  
from 2.4V to 12V or from ±2.4V to ±6V dual supplies.  
5.5ns at 5mV Overdrive  
Rail-to-Rail Inputs  
Rail-to-Rail Complementary Outputs (TTL/CMOS  
Compatible)  
Specified at 2.7V, 5V and ±5V Supplies  
The LT1711/LT1712 are designed for ease of use in a  
variety of systems. In addition to wide supply voltage  
flexibility, rail-to-rail input common mode range extends  
100mV beyond both supply rails, and the outputs are  
protected against phase reversal for inputs extending  
furtherbeyondtherails. Also, therail-to-railinputsmaybe  
taken to opposite rails with no significant increase in input  
current. The rail-to-rail matched complementary outputs  
interface directly to TTL or CMOS logic and can sink 10mA  
towithin0.5VofGNDorsource10mAtowithin0.7VofV+.  
Output Latch  
Inputs Can Exceed Supplies Without Phase Reversal

APPLICATIO S  
High Speed Automatic Test Equipment  
Current Sense for Switching Regulators  
Crystal Oscillator Circuits  
High Speed Sampling Circuits  
The LT1711/LT1712 have internal TTL/CMOS compatible  
latches for retaining data at the outputs. Each latch holds  
data as long as the latch pin is held high. Latch pin  
hysteresis provides protection against slow moving or  
noisy latch signals. The LT1711 is available in the 8-pin  
MSOP package. The LT1712 is available in the 16-pin  
narrow SSOP package.
