LTC6752IMS8-2#TRPBF

LTC6752IMS8-2#TRPBF is a 280MHz, 2.9ns comparator with rail-to-rail input and CMOS output. It is a family of very high speed comparators capable of supporting toggle rates up to 280MHz. This comparator exhibits low propagation delays of 2.9ns, and fast rise/fall times of 1.2ns. There are a total of 5 members in the LTC6752 family, with different options for separate input and output supplies, shutdown, output latch, adjustable hysteresis, complementary outputs, and package. Outputs are CMOS and separate supply options can operate down to 1.71V, allowing for directly interfacing to 1.8V logic devices. The low propagation delay of only 2.9ns combined with low dispersion of only 1.8ns makes this comparator an excellent choice for critical timing applications. Application includes clock and data recovery, level shifting, high speed data acquisition systems, window comparators, high speed line receivers, fast crystal oscillators, time of flight measurements, time domain reflectometry.
