Overview
The LTC6754IUD#TRPBF is a high-speed rail-to-rail input comparator with LVDS-compatible outputs manufactured by Analog Devices Inc. It operates on a supply voltage range of 2.4V to 5.25V and features a propagation delay of 1.8ns typical, with an overdrive dispersion of 1ns. The device supports a toggle rate up to 890Mbps and includes a shutdown pin for power reduction. It utilizes a 12-lead QFN package and provides separate supplies for the input and output stages.
Feature Summary
- Features rail-to-rail inputs that extend beyond both supply rails
- Includes LVDS compatible differential output stage
- Provides separate positive supply pins for input and output stages
- Offers adjustable hysteresis and output latching capabilities
Applications
- Clock and data recovery circuits
- High speed line receivers
- Time domain reflectometry systems
- Window comparators
- Level translation applications
Procurement Notes
Verify the specific temperature grade suffix 'I' corresponds to the required operating range of -40°C to 85°C. Confirm the '#TRPBF' designation indicates tape and reel packaging. Ensure the QFN package thermal requirements are met in the final design layout.
Selection Notes
Select this component when low propagation delay and minimal dispersion are critical for timing accuracy. The separate VCCI and VCCO pins allow for optimized power consumption and noise isolation between sensitive inputs and logic outputs. Verify input common mode voltage ranges against the application signals.
Part Context
This part belongs to the LTC6754 family of high-speed comparators. The 'I' suffix denotes the industrial temperature range variant (-40°C to 85°C), while the 'H' suffix covers the extended range. The 'UD' specifies the 12-lead QFN package format.

FAQ
How does the device handle input voltages exceeding the supply rails?
The LTC6754 features rail-to-rail inputs that can operate from VEE – 0.2V to VCCI + 0.1V without damage.
What is the function of the LE/HYST pin?
The LE/HYST pin allows users to adjust the input hysteresis or latch the output state to capture the comparator's status.
