The LT1719CS8#PBF is a 4.5ns UltraFast Comparator with rail-to-rail output optimized for low voltage operation. The input voltage range extends from 100mV below VEE to 1.2V below VCC. Internal hysteresis makes the LT1719 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. A shutdown control allows for reduced power consumption and extended battery life in portable applications. The LT1719S8 has separate supply pins for the input and output stages that allow flexible operation, accommodating separate voltage ranges for the analogue input and the output logic. The input stage is protected against damage from large differential signals, up to and beyond a differential voltage equal to the supply voltage, limited only by the absolute maximum currents noted.
