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.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 swingoutput stages are designed to directly drive 400 mV into 50 ? terminated to a voltage (VTERM = VCCO ? 2 V).HMC974LC3C features high speed latches that can either be enabled to latch the output data or left in the track mode toimplement a tracking window comparator.Applications Automatic test equipment (ATE) High speed instrumentation Clock and data restoration Semiconductor test systems Threshold detection in electronic warfare systems
