LTC6752HUD-3#TRPBF

Overview

The LTC6752HUD-3#TRPBF is a single-channel, very high-speed analog comparator from the LTC6752 family. It features rail-to-rail inputs and CMOS outputs with separate input (VCC) and output (VDD) supply options. The device supports toggle rates up to 280MHz with a typical propagation delay of 2.9ns and rise/fall times of 1.2ns. Input supply voltage ranges from 2.45V to 5.25V, while the output supply operates from 1.71V to 3.5V. It includes shutdown functionality for power reduction and is housed in a 12-lead QFN package.

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
Shutdown pin enables reduced power consumption by placing the device in low-current mode
Low propagation delay dispersion ensures accurate timing in critical applications

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 500 pieces. Confirm the 'H' grade designation corresponds to the extended temperature range of -40°C to +125°C. Ensure the order number matches the exact pinout and feature set required for the design, as other family members may lack the shutdown or latch functions.

Selection Notes

Select this part when separate input and output supplies are needed to interface with lower voltage logic levels. The inclusion of a shutdown pin makes it suitable for battery-powered systems requiring power management. Verify that the 280MHz toggle rate meets the system's frequency requirements and that the QFN package fits the available PCB footprint.

Part Context

This component belongs to the LTC6752 family of ultra-fast comparators. The '-3' suffix identifies it as the version with separate VCC and VDD supplies, complementary outputs, latching/hysteresis capability, and a shutdown pin. It is designed to replace older ADCMP60X family parts while offering improved speed and flexibility through its modular feature set.
