HMC974LC3CTR-R5

Overview

The HMC974LC3CTR-R5 is a silicon germanium monolithic ultra-fast window comparator featuring reduced swing positive emitter-coupled logic (RSPECL) output drivers with level latching. It operates at 10 GHz with an equivalent input bandwidth of 11 GHz and a propagation delay of 88 ps. The device utilizes a 16-terminal 2.9 mm × 2.9 mm LCC package, supports differential latch control, and dissipates 240 mW.

Feature Summary

• Features three single-ended negative logic outputs to detect if an analog input signal is above, below, or between two reference levels.
• Incorporates high-speed latches that can be enabled for data latching or left in track mode for tracking window comparison.
• Designed with reduced swing output stages capable of directly driving 400 mV into 50 Ω terminated loads.

Applications

• Automatic test equipment (ATE)
• High speed instrumentation
• Clock and data restoration
• Semiconductor test systems
• Threshold detection in electronic warfare systems

Selection Notes

Select this component when a high-speed window comparator with precise threshold detection is required. Consider the 16-terminal ceramic leadless chip carrier package for surface mount applications. Evaluate the power supply requirements and thermal management needs associated with the specified power dissipation.

Part Context

This part belongs to the HMC974 series of high-speed window comparators manufactured by Analog Devices Inc. It is designed for demanding RF and microwave applications requiring fast response times and accurate voltage window monitoring within complex signal processing chains.

Replacement Considerations

HMC974LC3C and HMC974LC3CTR are confirmed substitutes within the same family offering identical electrical specifications and pin configurations.

FAQ

What are the three output states of the HMC974LC3CTR-R5?

The device provides Under-range (URB), Window (WOUTB), and Over-range (ORB) outputs, which are asserted low based on the analog input voltage relative to the RT and RB reference pins.

How does the latch functionality operate?

The device features differential latch enable inputs (LE and LE). When enabled, it latches the output data; otherwise, it remains in track mode to continuously monitor the input signal against the window thresholds.
