LTC6754HSC6#PBF

Overview

The LTC6754HSC6#PBF is a high-speed rail-to-rail input comparator with LVDS-compatible outputs manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.4V to 5.25V and features a typical propagation delay of 1.8ns with an overdrive dispersion of 1ns. The device supports toggle rates up to 890Mbps and includes a shutdown pin for power reduction, waking in 120ns. It utilizes a 6-lead SC70 package and maintains an operating temperature range from -40°C to +125°C.

Feature Summary

• High-speed operation with low propagation delay and minimal overdrive dispersion
• Rail-to-rail inputs extending beyond both supply rails
• LVDS compatible differential output stage
• Shutdown mode capability for reduced power consumption

Applications

• Clock and data recovery circuits
• Level translation between logic families
• High-speed data acquisition systems
• Time domain reflectometry applications
• Time of flight measurements

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature grade. Ensure compatibility with the required supply voltages and load conditions before integration. Confirm lead-free finish status and RoHS compliance requirements for your manufacturing process.

Selection Notes

Select this component for timing-critical designs requiring fast response times and low jitter. Consider the separate input and output supply pins available in other packages if isolation is needed, though the SC70 version combines them. Evaluate the need for adjustable hysteresis or latching features, which are present in QFN variants but absent in the SC70 package.

Part Context

This part belongs to the LTC6754 family of high-speed comparators designed for demanding signal processing tasks. The family offers various package options including SC70 and QFN, providing flexibility for different board space and thermal requirements while maintaining consistent electrical performance characteristics across the series.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify that any replacement matches the required propagation delay, supply voltage range, and package dimensions.
