LTC6752HSC6-1

Overview

The Analog Devices LTC6752HSC6-1 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 a single supply voltage ranging from 2.45V to 3.5V. Key electrical characteristics include an input offset voltage of ±1.2mV, quiescent current of 4.5mA, and output current capability of ±22mA. It is housed in a 6-lead plastic SC-70 package and specified for operation from -40°C to +125°C.

Feature Summary

• Rail-to-rail inputs extend beyond both supply rails for wide common-mode range
• CMOS outputs provide direct interfacing to logic devices
• Integrated latching and adjustable hysteresis via LE/HYST pin
• Low propagation delay dispersion ensures critical timing accuracy

Applications

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

Procurement Notes

Verify the specific suffix HSC6-1 against official documentation to confirm the SC-70 package and temperature grade. Ensure the ordering code matches the required lead-free finish and tape-and-reel specifications. Confirm availability through designated sales channels as distribution may vary by region.

Selection Notes

Select this component when low jitter and fast toggle rates are required. The separate supply option allows independent optimization of input and output stages. Consider the integrated latch feature if signal holding is necessary. Verify that the SC-70 package fits the design constraints compared to TSOT-23 or QFN alternatives.

Part Context

This part belongs to the LTC6752 family of ultra-high-speed comparators. The family includes variants with different supply configurations, shutdown pins, and complementary outputs. The HSC6-1 specifically denotes the industrial/high-temperature grade version in the compact SC-70 package with latching capabilities.

Replacement Considerations

The datasheet identifies the ADCMP60X family as a direct replacement option. Verify pin compatibility and electrical performance matching before substitution.
