LT1720IDD#PBF

LT1720 is an UltraFast™ dual 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 this 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 this minimize parasitic effects by placing the most sensitive inputs (inverting) away from the outputs, shielded by the power rails. This is ideal for systems where small size and low power are paramount. Typical applications are high speed differential line receiver, crystal oscillator circuits, window comparators, threshold detectors/discriminators, pulse stretchers, zero-crossing detectors, high speed sampling circuits.
