LTC6752ISC6-4

Overview

The LTC6752ISC6-4#TRMPBF is a single-channel, very high-speed analog comparator from Analog Devices. It features rail-to-rail inputs and CMOS outputs within a 6-lead SC-70 package. The device supports toggle rates up to 280MHz with a typical propagation delay of 2.9ns and rise/fall times of 1.2ns. It operates on a single supply voltage ranging from 2.45V to 3.5V. Key electrical characteristics include an input offset voltage of ±1.2mV (typical), low jitter of 4.5ps RMS at 100MHz, and an output current capability of ±22mA. The specified operating temperature range for the 'I' grade is -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage allows signal processing across the full supply voltage range.
• CMOS output stage provides direct interfacing capabilities with standard logic families.
• Integrated latching function and adjustable hysteresis via the LE/HYST pin for noise immunity and state retention.
• Low dispersion and jitter performance suitable for critical timing applications.

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces. Confirm the 'I' designation matches the required -40°C to +85°C industrial temperature range. Ensure the SC-70 package footprint aligns with the PCB layout. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a single-channel comparator with integrated latch functionality is required in a small SC-70 package. It is appropriate for designs needing rail-to-rail input swing and CMOS outputs. Consider the separate supply options if different input and output voltage levels are necessary, though this specific part uses a single supply configuration.

Part Context

This part belongs to the LTC6752 family of ultra-high-speed comparators. The family includes variants with different pin counts, supply configurations, and output types. The LTC6752-4 variant specifically offers latching and hysteresis features in a compact 6-lead SC-70 package, distinguishing it from the basic LTC6752 and other multi-supply versions.

Replacement Considerations

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