The HMC974LC3C is a SiGe monolithic, ultra fast window comparator with level latched output driver with reduced swings. The window comparator is based on the HMC674LC3C single comparator and incorporates two such comparators and additional output logic. Three output ports detect whether an analog input signal is above, below or between two reference levels supplied at its input.
The outputs are single-ended negative logic. Incorporating two proven comparators at the input provides good DC and dynamic matching and reduces the input capacitance. The reduced swing output stages are designed to directly drive 400 mV into 50 Ohms terminated to a voltage Vterm = Vcco-2 V.
The HMC974LC3C features high speed latches that can either be enabled to latch the output data, or can be left in the transparent mode to implement a tracking window comparator.
