LTC6752ISC6-4#TRPBF

Overview

The LTC6752ISC6-4#TRPBF is a high-speed analog comparator from the LTC6752 family, housed in a 6-lead SC-70 package. It features rail-to-rail inputs and CMOS outputs with separate input and output supply options. Key electrical parameters include a propagation delay of 2.9ns, a toggle rate up to 280MHz, and an input offset voltage of ±1.2mV. The device operates on an input supply (VCC) ranging from 2.45V to 5.25V and an output supply (VDD) from 1.71V to 3.5V. It supports a quiescent current of approximately 4.5mA and provides an output current capability of ±22mA.

Feature Summary

• Rail-to-rail inputs extend beyond both supply rails for flexible signal interfacing
• Separate input and output supply options allow direct connection to 1.8V logic devices
• Low propagation delay and low jitter support critical timing applications
• CMOS outputs provide strong drive capability with ±22mA output current

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the ISC6 designation corresponds to the SC-70 package and I-grade temperature range. Ensure the -4 variant matches the required separate supply configuration. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and revision status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring ultra-fast switching speeds and precise timing. The separate supply architecture is ideal for level shifting between different voltage domains. Consider the SC-70 package size for space-constrained layouts. Evaluate the low dispersion characteristics if maintaining signal integrity across varying overdrive conditions is critical for the application performance.

Part Context

This part belongs to the LTC6752 family of very high-speed comparators designed for demanding signal processing tasks. The family includes variants with different packages and feature sets such as shutdown pins or latching capabilities. The LTC6752-4 specifically offers separate supplies and complementary outputs in a compact SC-70 form factor, distinguishing it from single-supply or latch-enabled siblings.

Replacement Considerations

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