LT1711/LT1712

Single/Dual 4.5ns, 3V/5V/±5V,

Rail-to-Rail Comparators

FEATURES

DESCRIPTIO

■

Ultrafast: 4.5ns at 20mV Overdrive

The LT^®1711/LT1712 are UltraFast^TM4.5ns 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⁺.

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.
