LTC6752HMS8-2#PBF

Overview

The LTC6752HMS8-2#PBF is a high-speed comparator from Analog Devices, housed in an 8-lead MSOP package. It supports toggle rates up to 280MHz with a propagation delay of 2.9ns and rise/fall times of 1.2ns. The device features rail-to-rail inputs operating between 2.45V and 5.25V, and separate CMOS outputs capable of interfacing with 1.8V logic via output supplies down to 1.71V. It includes shutdown functionality for power reduction and operates within specified temperature ranges.

Feature Summary

• Rail-to-rail input capability extending beyond both supply rails
• Separate input and output supply options for direct 1.8V logic interfacing
• Shutdown pin enables reduced power consumption during idle states
• Low propagation delay dispersion ensures precise timing accuracy

Applications

• Clock and data recovery circuits
• High-speed line receivers
• Time of flight measurements
• Fast crystal oscillators

Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when sourcing. Confirm the H-grade designation matches the required -40°C to +125°C industrial temperature range for your application environment. Ensure the MS8 package footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high-frequency signal comparison with minimal jitter. The separate VCC and VDD supplies allow optimization of input stage voltage against output drive requirements. Consider the shutdown feature if system power management is critical. Verify that the 22mA output current capability meets the load driving needs of downstream logic gates.

Part Context

This part belongs to the LTC6752 family of ultra-high-speed comparators. It serves as a direct replacement for the ADCMP60X family. The family offers various packages including TSOT-23, SC70, MSOP, and QFN, with options for latching, hysteresis, and complementary outputs depending on the specific sub-model variant selected.

Replacement Considerations

The datasheet explicitly identifies the ADCMP60X family as a direct replacement target. Verify pin compatibility and electrical specifications against the legacy component to ensure seamless integration without circuit redesign.
