LTC6752ISC6-4#TRMPBF

Overview

The LTC6752ISC6-4#TRMPBF is a high-speed analog comparator from Analog Devices, packaged in a 6-lead SC-70 format. It features rail-to-rail inputs and CMOS outputs with a propagation delay of 2.9ns and a toggle rate up to 280MHz. The device operates on a single supply voltage ranging from 2.45V to 3.5V. Key electrical characteristics include an input offset voltage of ±1.2mV, low jitter of 4.5ps RMS at 100MHz, and an output current capability of ±22mA. It functions within a specified temperature range of –40°C to +85°C.

Feature Summary

• Rail-to-rail input capability extending beyond both supply rails
• CMOS outputs allowing direct interfacing with logic devices
• Low propagation delay combined with minimal overdrive dispersion for critical timing
• High toggle rate supporting frequencies up to 280MHz

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces. Confirm the ISC6 designation corresponds to the industrial temperature grade (-40°C to +85°C) and the SC-70 package type. Ensure compatibility with the required supply voltage range of 2.45V to 3.5V before integration into the design.

Selection Notes

Select this component when ultra-fast response times are required for signal comparison. The rail-to-rail input allows handling signals that swing near or slightly beyond the supply rails. The CMOS output simplifies interface requirements with standard digital logic families without needing additional pull-up resistors.

Part Context

This part belongs to the LTC6752 family of very high-speed comparators. The family includes variants with separate input/output supplies, shutdown pins, and complementary outputs. This specific model represents the -4 variant, which provides a single-ended CMOS output in a compact SC-70 package suitable for space-constrained designs.

Replacement Considerations

The datasheet identifies the ADCMP60X family as a direct replacement option. Verify pinout compatibility and electrical specifications against the target application requirements before substituting.
