LTC6752HMS8-2#TRPBF

Overview

The LTC6752HMS8-2#TRPBF is a high-speed comparator featuring rail-to-rail inputs and CMOS outputs. It supports toggle rates up to 280MHz with a propagation delay of 2.9ns. The device utilizes separate input and output supply rails, allowing the output stage to interface directly with 1.8V logic. Key electrical characteristics include an input voltage range from VEE–0.2V to VCC+0.1V, an output current capability of ±22mA, and a low quiescent current of 4.5mA. It includes a shutdown pin for power reduction and operates within a temperature range of –40°C to 125°C.

Feature Summary

• Rail-to-rail inputs extend beyond both supply rails for flexible signal handling
• Separate input and output supply options enable direct interfacing with 1.8V logic devices
• Integrated shutdown pin reduces power consumption when the device is not in use

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm the H-grade designation matches the required operating temperature range of –40°C to 125°C for your application environment. Ensure the MSOP-8 package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when high toggle rates and low propagation delay are critical. The separate supply architecture is ideal for level shifting applications where input and output logic voltages differ. Consider the shutdown feature if power management during idle states is a design priority compared to single-supply alternatives.

Part Context

This part belongs to the LTC6752 family of very high-speed comparators. The family offers various configurations including latch/hysteresis features and complementary outputs. The MSOP-8 package provides a compact solution for space-constrained designs requiring high performance in clock recovery and data acquisition systems.

Replacement Considerations

The datasheet identifies the ADCMP60X family as a direct replacement option. Verify compatibility regarding supply voltage ranges and package dimensions when substituting.
