GENERAL DESCRIPTION
The HMC974LC3C is a silicon germanium (SiGe) monolithic,
ultra fast window comparator that features reduced swing
positive emitter-coupled logic (RSPECL) output drivers that are
level latched. Three output ports detect whether an analog input
signal is above, below, or between two reference levels supplied
at the input (see Figure 2).

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 Ω
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 left in the track mode to
implement a tracking window comparator.
