Description

The LT®1711/LT1712 are UltraFastTM 4.5ns comparators featuring rail-to-rail inputs, rail-to-rail complementary outputs 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. 

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 further beyond the rails. Also, the rail-to-rail inputs may be 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 to within 0.5V of GND or source 10mA to within 0.7V of V +. 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.
