Product Details

The LT1711 is 4.5ns comparator featuring rail-to-rail inputs, rail-to-rail complementary outputs and an output latch. Optimized for 3V and 5V power supplies, it operates over a single supply voltage range from 2.4V to 12V or from ±2.4V to ±6V dual supplies.

The LT1711 is designed for ease of use in a variety of systems. In addition to the wide supply voltage flexibility, the 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 has an internal TTL/CMOS compatible latch for retaining data at the outputs. The 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.
