LTC6752/LTC6752-1/ LTC6752-2/LTC6752-3/ LTC6752-4 280MHz, 2.9ns Comparator Family with Rail-to-Rail Inputs and CMOS Outputs Fea T Descrip T n Very High Toggle Rate: 280MHz The LTC 6752 is a family of very high speed comparators n Low Propagation Delay: 2.9ns capable of supporting toggle rates up to 280MHz. These n Rail-to-Rail Inputs Extend Beyond Both Rails comparators exhibit low propagation delays of 2.9ns, and n Output Current Capability: 22mA fast rise/fall times of 1.2ns. There are a total of 5 members n Low Quiescent Current: 4.5mA in the LTC6752 family, with different options for separate n Features within the LTC6752 Family: input and output supplies, shutdown, output latch, adjust- n 2.45V to 5.25V Input Supply and 1.71V to 3.5V able hysteresis, complementary outputs, and package. Output Supply (Separate Supply Option) The LTC6752 comparators have rail-to-rail inputs that n 2.45V to 3.5V Supply (Single Supply Option) operate from 2.45V, up to 3.5V or 5.25V, depending on n Shutdown Pin for Reduced Power the option. The outputs are CMOS and the separate supply n Output Latch and Adjustable Hysteresis options can operate down to 1.71V, allowing for directly n Complementary Outputs interfacing to 1.8V logic devices. n Packages: TSOT-23, SC70, MSOP, 3mm 3mm QFN n The low propagation delay of only 2.9ns combined with Direct Replacement for ADCMP60X Family n low dispersion of only 1.8ns (10mV to 125mV overdrive Fully Specified from 55C to 125C variation) makes these comparators an excellent choice for critical timing applications. Similarly, the fast toggle a T rate and the low jitter of 4.5ps RMS (100mV , 100MHz P-P input) make the LTC6752 family ideally suited for high n Clock and Data Recovery frequency line driver and clock recovery circuits. n Level Shifting n L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Analog High Speed Data Acquisition Systems Devices, Inc.
