Analog Devices Inc. LTC6752ISC6-1#TRMPBF

Overview

LTC6752ISC6-1#TRMPBF from Analog Devices is a high-speed rail-to-rail input comparator with CMOS output, 2.9ns propagation delay, 280MHz toggle rate, and 1.2ns rise/fall times. It operates from 2.45V to 3.5V single supply and delivers ±22mA output drive, enabling direct interface with 1.8V logic in clock recovery and high-speed data acquisition systems.

For engineers reviewing the LTC6752ISC6-1#TRMPBF datasheet, LTC6752ISC6-1#TRMPBF pinout, LTC6752ISC6-1#TRMPBF application, or LTC6752ISC6-1#TRMPBF equivalent, key selection criteria include propagation delay dispersion (1.8ns), input common-mode range extending beyond rails (VEE – 0.2V to VCC + 0.1V), latch/hysteresis capability, and SC70-6 package compatibility for space-constrained timing circuits.

Technical Context

The LTC6752ISC6-1#TRMPBF implements a high-gain, low-dispersion comparator architecture optimized for sub-3ns timing-critical decisions. Its rail-to-rail input stage supports common-mode voltages from –0.2V below VEE to +0.1V above VCC, while the CMOS output stage drives loads directly without external level-shifting.

This variant includes latching and adjustable hysteresis via the LE/HYST pin (1.05–1.45V threshold), enabling configurable noise immunity and state retention. It lacks shutdown and complementary outputs-features reserved for LTC6752-2/–3/–4 variants-and uses a single-supply configuration (VCC–VEE) rather than separate input/output supplies.

The LTC6752 family was designed for ultra-low-latency, high-accuracy signal decision-making in timing-critical systems-including clock/data recovery, time-of-flight measurement, and high-speed test equipment-where sub-3ns propagation delay and rail-to-rail input flexibility are essential.

FAQ

What is the maximum operating supply voltage for the LTC6752ISC6-1#TRMPBF?

The LTC6752ISC6-1#TRMPBF supports a total supply voltage (VCC–VEE) of 2.45V to 3.5V per its datasheet specifications. Absolute maximum rating is 3.6V. Exceeding 3.5V may degrade performance or reliability, and operation above 3.6V risks permanent damage. This single-supply range excludes separate-output-supply variants like LTC6752-2.

Does the LTC6752ISC6-1#TRMPBF support rail-to-rail input voltage beyond the supply rails?

Yes, the LTC6752ISC6-1#TRMPBF supports an input common-mode range from VEE – 0.2V to VCC + 0.1V. This rail-overdrive capability allows it to accept AC-coupled signals or mismatched source voltages without clamping diodes or external biasing-critical for interfacing with transformers or high-side current sense amplifiers.

How does the LE/HYST pin function on the LTC6752ISC6-1#TRMPBF?

The LE/HYST pin on the LTC6752ISC6-1#TRMPBF serves dual functions: at ≥1.7V, it disables hysteresis and enables transparent latching; at ≤0.3V, it guarantees latched output state; when floating, it defaults to ~5mV hysteresis. Internal resistance is 15–25kΩ, enabling simple resistor-divider programming for custom hysteresis levels up to 40mV.

What is the guaranteed temperature range for the LTC6752ISC6-1#TRMPBF?

The LTC6752ISC6-1#TRMPBF is rated for operation from –40°C to +85°C (Industrial grade). This is confirmed by its part marking "I" suffix and ordering information table, which lists "LTC6752ISC6-1#TRMPBF" explicitly under the –40°C to 85°C temperature column-not the H (–40°C to 125°C) or MP (–55°C to 125°C) grades.

Can the LTC6752ISC6-1#TRMPBF drive a 50Ω transmission line directly?

Yes, the LTC6752ISC6-1#TRMPBF can drive a 50Ω load directly: its CMOS output delivers ±22mA, yielding ~1.1V swing into 50Ω (at VCC = 3.3V), sufficient for LVCMOS/LVTTL signaling. Rise/fall times remain <1.35ns under this load, preserving signal integrity for short traces (<5cm) without termination resistors.
