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 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 is low 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 resistive divider.
