LT1715 4ns, 150MHz Dual Comparator with Independent Input/Output Supplies FEATURES DESCRIPTION n UltraFast: 4ns at 20mV Overdriven The LT 1715 is an UltraFast dual comparator optimized for n 150MHz Toggle Frequency low voltage operation. Separate supplies allow independent n Separate Input and Output Power Supplies analog input ranges and output logic levels with no loss of n Low Power: 4.6mA per Comparator at 3V performance. The input voltage range extends from 100mV n Pinout Optimized for High Speed Use below V to 1.2V below V . Internal hysteresis makes the EE CC n Output Optimized for 3V and 5V Supplies LT1715 easy to use even with slow moving input signals. n TTL/CMOS Compatible Rail-to-Rail Output The rail-to-rail outputs directly interface toTTL and CMOS. n Input Voltage Range Extends 100mV The symmetric output drive results in similar rise and fall Below Negative Rail times that can be harnessed for analog applications or for n Internal Hysteresis with Speci ed Limits easy translation to other single supply logic levels. n Speci ed for 40C to 125C Temperature Range The LT1715 is available in the 10-pin MSOP package. The n Available in the 10-pin MSOP Package pinout of the LT1715 minimizes parasitic effects by placing the most sensitive inputs away from the outputs, shielded by the power rails.
