LT1016 UltraFast Precision 10ns Comparator FEATURES DESCRIPTION n UltraFast (10ns typ) The LT 1016 is an UltraFast 10ns comparator that interfaces n Operates Off Single 5V Supply or 5V directly to TTL/CMOS logic while operating off either 5V n Complementary Output to TTL or single 5V supplies. Tight offset voltage specifications n Low Offset Voltage and high gain allow the LT1016 to be used in precision n No Minimum Input Slew Rate Requirement applications. Matched complementary outputs further n No Power Supply Current Spiking extend the versatility of this comparator. n Output Latch Capability A unique output stage provides active drive in both direc- tions for maximum speed into TTL/CMOS logic or passive loads, yet does not exhibit the large current spikes found APPLICATIONS in conventional output stages. This allows the LT1016 to n High Speed A/D Converters remain stable with the outputs in the active region which, High Speed Sampling Circuits greatly reduces the problem of output glitching when Line Receivers the input signal is slow moving or islow level. Extended Range V-to-F Converters The LT1016 has a LATCH pin which will retain input data Fast Pulse Height/Width Discriminators at the outputs, when held high. Quiescent negative power Zero-Crossing Detectors supply current is only 3mA. This allows the negative supply Current Sense for Switching Regulators pin to be driven from virtually any supply voltage with a High Speed Triggers simple resistivedivider. Device performance is not affected Crystal Oscillators by variations in negative supply voltage. All registered trademarks and trademarks are the property of their respective owners. Analog Devices offers a wide range of comparators in addition to the LT1016 that address different applica- tions. See the Related Parts section on the back page of the data sheet.
