LTC6752IMS8-2#TRPBF

Overview

The LTC6752IMS8-2#TRPBF is a high-speed analog comparator from Analog Devices, packaged in an 8-lead MSOP. It features rail-to-rail inputs and CMOS outputs with separate input (VCC) and output (VDD) supply pins. The device supports toggle rates up to 280MHz with a typical propagation delay of 2.9ns. It includes a shutdown pin for power reduction and an LE/HYST pin for latching or adjustable hysteresis functionality.

Feature Summary

• Rail-to-rail inputs extend beyond both supply rails for flexible signal interfacing
• Separate input and output supply options allow direct interfacing to 1.8V logic devices
• Shutdown pin enables reduced power consumption during idle periods
• LE/HYST pin provides configurable output latch and adjustable hysteresis capabilities

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when ordering. Confirm the IMS8 package designation matches your PCB footprint requirements. Ensure the -2 variant selection aligns with your need for separate VCC and VDD supplies rather than a single supply configuration.

Selection Notes

Select this part when separate input and output voltage domains are required for level shifting. The -2 suffix indicates the inclusion of a shutdown control pin and latch/hysteresis functionality. Verify that the 280MHz toggle rate meets your system's frequency requirements compared to slower comparator alternatives.

Part Context

This component belongs to the LTC6752 family of very high-speed comparators. The family includes variants with different supply configurations, packages, and feature sets such as complementary outputs or fixed hysteresis. The IMS8-2 variant specifically targets applications requiring independent supply rails and power management controls.

Replacement Considerations

The datasheet identifies the ADCMP60X family as a direct replacement option. Verify pin compatibility and electrical specifications before substituting.
