ANALOG DEVICES LT1721IS#PBF Analogue Comparator, High Speed, 4 Channels, 4.5 ns, 2.7V to 6V, SOIC, 16 Pins

LT1721IS#PBF is an UltraFast� quad comparator optimized for single supply operation, with a supply voltage range of 2.7V to 6V. The input voltage range extends from 100mV below ground to 1.2V below the supply voltage. Internal hysteresis makes the device easy to use even with slow-moving input signals. The rail-to-rail outputs directly interface to TTL and CMOS. Alternatively, the symmetric output drive can be harnessed for analogue applications or for easy translation to other single-supply logic levels. The pinouts of the device minimize parasitic effects by placing the most sensitive inputs (inverting) away from the outputs, shielded by the power rails. It is ideal for systems where small size and low power are paramount. It is used in applications such as high-speed differential line receivers, crystal oscillator circuits, window comparators, threshold detectors/discriminators, pulse stretchers, zero-crossing detectors, and high-speed sampling circuits.
