The LT1721CS#PBF is an UltraFast? dual/quad single-supply Comparator optimized for single supply operation, with a supply voltage range of 2.7 to 6V. The input voltage range extends from 100mV below ground to 1.2V below the supply voltage. Internal hysteresis makes the LT1721 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 pin-outs of the LT1721 minimize parasitic effects by placing the most sensitive inputs (inverting) away from the outputs, shielded by the power rails. The LT1721 is ideal for systems where small size and low power are paramount.
