Analog Devices Inc. LTC6752IMS8-2#TRPBF

Overview

LTC6752IMS8-2#TRPBF from Analog Devices is a high-speed rail-to-rail input comparator with CMOS outputs, 2.9ns propagation delay, 280MHz toggle rate, and separate input/output supplies (VCC/VDD). It features latching capability, adjustable hysteresis via the LE/HYST pin, and operates from –40°C to 85°C in an 8-lead MSOP package - ideal for clock/data recovery and high-speed line receiver applications.

For engineers reviewing the LTC6752IMS8-2#TRPBF datasheet, LTC6752IMS8-2#TRPBF pinout, LTC6752IMS8-2#TRPBF application, or LTC6752IMS8-2#TRPBF equivalent, this device delivers low overdrive dispersion (1.8ns), 4.5ps RMS jitter at 100MHz, ±22mA output drive, and rail-to-rail input range extending beyond both rails - critical for timing-critical signal conditioning in data acquisition and TDR systems.

Technical Context

The LTC6752IMS8-2#TRPBF implements a dual-supply architecture: VCC (2.45V–5.25V) powers the input stage, while VDD (1.71V–3.5V) independently powers the CMOS output stage, enabling direct interfacing with 1.8V logic. Its internal latch and adjustable hysteresis are controlled via the LE/HYST pin, supporting precise threshold control and noise immunity in dynamic signal environments.

This variant belongs to the LTC6752-2 subfamily, confirmed by its MS8 package, inclusion of shutdown (SHDN), latch/hysteresis (LE/HYST), and complementary outputs (Q and Q). It exhibits low common-mode dispersion (240ps) and maintains stable propagation delay across 10mV–125mV overdrive - essential for deterministic timing in high-frequency sampling and level-shifting circuits.

FAQ

What is the function of the LE/HYST pin on the LTC6752IMS8-2#TRPBF?

The LE/HYST pin on the LTC6752IMS8-2#TRPBF serves a dual role: when pulled low (<0.3V), it enables transparent latching of the output state; when left floating, it provides 5mV of input hysteresis to suppress noise-induced output toggling. At 0.8V, hysteresis increases to ~40mV - allowing dynamic noise-margin adjustment without external components. This pin is central to the LTC6752IMS8-2#TRPBF's adaptability in real-time signal conditioning.

Does the LTC6752IMS8-2#TRPBF support independent input and output supplies?

Yes, the LTC6752IMS8-2#TRPBF supports fully independent supplies: VCC (2.45V–5.25V) powers the input comparator stage, while VDD (1.71V–3.5V) powers the CMOS output drivers. This architecture allows the LTC6752IMS8-2#TRPBF to accept wide-range analog inputs while driving 1.8V, 2.5V, or 3.3V logic directly - eliminating level shifters and reducing BOM count in mixed-voltage systems.

What is the guaranteed operating temperature range for the LTC6752IMS8-2#TRPBF?

The LTC6752IMS8-2#TRPBF is rated for operation from –40°C to +85°C (Industrial grade, denoted by the "I" suffix in LTC6752IMS8-2). All electrical specifications - including 2.9ns propagation delay, 4.5ps RMS jitter, and 280MHz toggle rate - are guaranteed across this full temperature range, making the LTC6752IMS8-2#TRPBF suitable for deployment in uncontrolled industrial enclosures and telecom infrastructure.

How does the LTC6752IMS8-2#TRPBF achieve low overdrive dispersion?

The LTC6752IMS8-2#TRPBF achieves 1.8ns overdrive dispersion (10mV–125mV input step variation) through proprietary input-stage design that minimizes gain-dependent delay shifts. This ensures consistent propagation delay regardless of signal amplitude - a critical feature for the LTC6752IMS8-2#TRPBF in applications like time-of-flight measurement and high-speed data slicing, where timing predictability must hold across varying input swing.

Can the LTC6752IMS8-2#TRPBF drive standard CMOS loads directly?

Yes, the LTC6752IMS8-2#TRPBF features true CMOS outputs capable of sourcing/sinking ±22mA into 5pF loads, with VOH ≤ 340mV below VDD and VOL ≤ 400mV above VEE (at 8mA). Its 1.2ns rise/fall time and rail-to-rail swing ensure clean, fast switching into standard 74LVC or 74ALVC logic families - confirming the LTC6752IMS8-2#TRPBF's readiness for direct interface without external buffers or termination networks.
