LTC6754ISC6

Overview

The LTC6754ISC6 is a high-speed, single-channel analog comparator manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with an LVDS-compatible differential output stage. The device operates within a supply voltage range of 2.4 V to 5.25 V and draws a typical operating current of 13.4 µA. Key electrical specifications include a propagation delay of 2.9 ns, an input offset voltage (Vos) of 750 µV, and an input bias current (Ib) of 2.5 µA. Each channel provides an output current capability of 3.6 mA. The component is designed for operation across an extended industrial temperature range from -40°C to +85°C and is housed in a compact 12-lead QFN package.

Feature Summary

• High-speed performance with low propagation delay for rapid signal processing
• LVDS-compatible differential output interface for noise immunity
• Rail-to-rail input and output functionality for wide dynamic range
• Low power consumption suitable for battery-operated applications

Applications

• High-speed data acquisition systems
• Portable instrumentation requiring low power
• Communication equipment interfaces
• Automotive sensor signal conditioning

Procurement Notes

Verify the specific suffix 'ISC6' against the official Analog Devices datasheet to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the required PCB footprint for the 12-lead QFN package. Confirm that the LVDS output requirements match the receiving circuitry standards. Check for any recent product change notices regarding manufacturing updates or pinout modifications before finalizing procurement.

Selection Notes

Select this component when a single-channel comparator with LVDS outputs is required. Consider the 2.9 ns propagation delay for timing-critical applications. Evaluate the 750 µV input offset voltage against system accuracy needs. Verify that the 2.4 V to 5.25 V supply range aligns with the available power rails. Compare the 13.4 µA quiescent current against other low-power alternatives if energy efficiency is the primary constraint.

Part Context

The LTC6754 belongs to a family of high-speed comparators from Analog Devices. It shares functional similarities with other members like the LTC6752 and LTC6755 but differs in channel count and specific output configurations. The ISC6 suffix typically denotes a specific thermal and mechanical variant within the broader LTC6754 product line, distinguishing it from commercial or military grade options.

Replacement Considerations

Direct replacements may include the LTC6752HDC6 for dual-channel applications or the LTC6755HDC6 for similar performance characteristics. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Consult the manufacturer's cross-reference guide for validated alternative part numbers.
