LTC6752HSC6-4#TRMPBF

Overview

The Analog Devices LTC6752HSC6-4#TRMPBF is a high-speed analog comparator featuring rail-to-rail inputs and CMOS outputs. It supports toggle rates up to 280MHz with a propagation delay of 2.9ns and rise/fall times of 1.2ns. The device operates on input supply voltages from 2.45V to 5.25V and output supplies from 1.71V to 3.5V. It includes latching and adjustable hysteresis capabilities, complementary outputs, and is housed in a 6-lead SC-70 package.

Feature Summary

• Features rail-to-rail inputs that extend beyond both supply rails for flexible signal interfacing.
• Provides complementary outputs alongside standard single-ended options.
• Includes integrated latching functionality and adjustable hysteresis via the LE/HYST pin.
• Supports separate input and output supply rails to facilitate direct interfacing with lower voltage logic.

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces. Confirm the H grade ensures operation across the full industrial temperature range of -40°C to +125°C. Ensure the SC-70 package dimensions match the target PCB footprint constraints during procurement planning.

Selection Notes

Select this part when low propagation delay and high toggle rates are critical. The separate supply option allows independent optimization of input and output stages. Verify that the required hysteresis levels can be achieved using the external LE/HYST pin configuration rather than internal fixed values.

Part Context

This component belongs to the LTC6752 family of ultra-high-speed comparators. The family offers various configurations including shutdown pins, different package types like TSOT-23 and QFN, and distinct electrical grades. This specific variant focuses on performance within a compact surface-mount form factor.

Replacement Considerations

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