This datasheet details the LT1711/LT1712 UltraFast 4.5ns comparators featuring rail-to-rail inputs and outputs with an internal latch.
The LT1711/LT1712 are UltraFast 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 devices are designed for ease of use in a variety of systems, offering wide supply voltage flexibility and protection against phase reversal for inputs extending beyond the rails.
The LT1711 is available in an 8-pin MSOP package, while the LT1712 is available in a 16-pin narrow SSOP package. Key features include rail-to-rail input common mode range extending 100mV beyond both supply rails and outputs that can sink or source 10mA to within 0.5V of GND or V+. The internal TTL/CMOS compatible latches retain data at the outputs as long as the latch pin is held high.
