Analog Devices Inc. LTC6752HMS8-2#PBF

Overview

LTC6752HMS8-2#PBF from Analog Devices is a high-speed rail-to-rail input comparator with CMOS outputs, 2.9ns propagation delay, 280MHz toggle rate, and operation over –40°C to 125°C. It features separate input/output supplies (VCC/VDD), latch/hysteresis control via LE/HYST pin, and is housed in an 8-lead MSOP package - optimized for clock/data recovery, high-speed line receivers, and time-of-flight measurement circuits.

For engineers reviewing the LTC6752HMS8-2#PBF datasheet, LTC6752HMS8-2#PBF pinout, LTC6752HMS8-2#PBF application, or LTC6752HMS8-2#PBF equivalent, this device delivers low-jitter (4.5ps RMS), fast rise/fall times (1.2ns), and configurable hysteresis - critical for precision timing, level-shifting, and high-frequency signal conditioning where propagation delay dispersion (<1.8ns) and common-mode rejection (>50dB) are design-critical.

Technical Context

The LTC6752HMS8-2#PBF implements a dual-supply architecture with independent VCC (2.45V–5.25V) and VDD (1.71V–3.5V) rails, enabling direct interfacing to 1.8V logic while accepting wide-range analog inputs. Its internal latch function is controlled by the LE/HYST pin, supporting both hysteresis adjustment and output latching modes.

Propagation delay skew is specified at ≤600ps (rising vs. falling edge), and overdrive dispersion remains tightly bounded at 1.8ns across 10mV–125mV input overdrive - ensuring deterministic timing behavior in high-speed sampling and threshold-detection applications.

FAQ

What is the maximum operating temperature rating for the LTC6752HMS8-2#PBF?

The LTC6752HMS8-2#PBF is rated for operation from –40°C to +125°C (H-grade), verified per Analog Devices' qualification standards and guaranteed across the full temperature range for all key parameters including propagation delay, offset voltage, and supply current.

Does the LTC6752HMS8-2#PBF support separate input and output supply rails?

Yes, the LTC6752HMS8-2#PBF supports independent VCC (2.45V–5.25V) for the input stage and VDD (1.71V–3.5V) for the CMOS output stage - enabling seamless interfacing between higher-voltage analog domains and low-voltage digital logic without external level shifters.

How does the LE/HYST pin function on the LTC6752HMS8-2#PBF?

The LE/HYST pin on the LTC6752HMS8-2#PBF serves dual roles: pulled low, it latches the output state; biased at intermediate voltages (e.g., 800mV), it adjusts input hysteresis from 5mV to 40mV - providing programmable noise immunity without external components.

What is the typical propagation delay and overdrive dispersion for the LTC6752HMS8-2#PBF?

The LTC6752HMS8-2#PBF has a typical propagation delay of 2.9ns (50mV overdrive) and overdrive dispersion of 1.8ns across 10mV–125mV input overdrive - ensuring consistent timing performance regardless of signal amplitude variations in high-speed detection applications.

Is the LTC6752HMS8-2#PBF pin-compatible with other members of the LTC6752 family?

No - the LTC6752HMS8-2#PBF uses the 8-lead MSOP (MS8) package with specific pin assignments for VCC, VDD, SHDN, and LE/HYST. Other variants like LTC6752HSC6-4#TRPBF (SC70-6) or LTC6752HUD-3#PBF (QFN-12) have different pin counts, layouts, and feature sets; PCB layout is not interchangeable.
