LTC6752HSC6-4

Overview

The LTC6752HSC6-4 is a high-speed analog comparator from Analog Devices, housed in a 6-lead SC-70 package. It features rail-to-rail inputs and CMOS outputs with separate input (VCC) and output (VDD) supply options. Key electrical parameters include a propagation delay of 2.9ns, toggle rates up to 280MHz, and an input offset voltage of ±1.2mV. The device operates on input supplies from 2.45V to 5.25V and output supplies from 1.71V to 3.5V. It supports a specified temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail inputs extend beyond both supply rails for flexible signal interfacing.
• Separate input and output supply options allow direct interfacing to 1.8V logic devices.
• Low propagation delay combined with low dispersion ensures accurate critical timing performance.
• CMOS outputs provide high current capability for driving loads directly.

Applications

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

Procurement Notes

Verify the specific suffix HSC6-4 against official documentation to confirm the SC-70 package and separate supply configuration. Ensure the required operating temperature grade matches the 'H' designation (-40°C to +125°C). Confirm lead-free finish requirements align with the #PBF or #TRPBF ordering codes provided in the manufacturer's order information table.

Selection Notes

Select this component when separate input and output supplies are necessary to interface with lower voltage logic levels while maintaining high-speed performance. The SC-70 package is suitable for space-constrained designs requiring a single channel. Consider the LTC6752-1 if latching or adjustable hysteresis functionality is required instead of the standard output found in the -4 variant.

Part Context

The LTC6752 family consists of five members offering various configurations including shutdown pins, complementary outputs, and latch capabilities. The -4 variant specifically provides separate VCC and VDD supplies in a compact SC-70 footprint without additional control features like shutdown or latching. This family serves as a direct replacement for older ADCMP60X series comparators.
