Product details
Overview
LTC6752HSC6-1#TRMPBF from Analog Devices is a high-speed rail-to-rail input comparator with CMOS output, 2.9ns propagation delay, 280MHz toggle rate, and 4.5ps RMS jitter (100MHz input). It operates from 2.45V to 3.5V single supply and features latching/adjustable hysteresis, targeting clock recovery and high-speed line receiver applications in industrial and automotive timing systems.
For engineers reviewing the LTC6752HSC6-1#TRMPBF datasheet, LTC6752HSC6-1#TRMPBF pinout, LTC6752HSC6-1#TRMPBF application, or LTC6752HSC6-1#TRMPBF equivalent, this device delivers verified low overdrive dispersion (1.8ns), rail-to-rail input range extending beyond both rails, ±22mA output drive, and guaranteed operation from –40°C to 125°C in SC70-6 package.
Technical Context
The LTC6752HSC6-1#TRMPBF implements a differential-input, single-ended-output comparator architecture with internal latch and adjustable hysteresis via the LE/HYST pin. Its rail-to-rail input stage supports common-mode voltages from VEE – 0.2V to VCC + 0.1V, enabling direct interfacing with diverse signal sources including crystal oscillators and LVDS receivers.
It uses separate internal biasing for input and output stages, allowing stable operation across VCC = 2.45V–3.5V while maintaining 1.2ns rise/fall times and <600ps propagation skew. The device exhibits 51dB typical CMRR and 59dB PSRR_VCC, making it suitable for noisy mixed-signal environments requiring precise threshold detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 2.9ns typical at 50mV overdrive - enables sub-3ns timing-critical decision paths in SERDES and TDR systems. |
| Toggle Rate | 280MHz - supports high-frequency clock/data recovery up to 280MSPS without duty-cycle degradation. |
| RMS Jitter | 4.5ps at 100MHz input - ensures <100fs timing uncertainty in precision sampling and phase alignment circuits. |
| Input Offset Voltage | ±1.2mV max - guarantees accurate threshold setting within 1.2mV across temperature and supply variation. |
| Supply Range | 2.45V to 3.5V single supply - compatible with 2.5V and 3.3V logic domains without level-shifting circuitry. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and industrial control applications. |
| Output Drive | ±22mA - directly drives 50Ω transmission lines or fan-out to multiple CMOS inputs without buffering. |
Pinout & Package
Package: 6-lead plastic SC70 (SC6), 2.0mm × 1.25mm footprint, exposed pad not present, moisture sensitivity level MSL1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 Q | CMOS Output | Active-high digital output referenced to VCC; sinks 22mA / sources 22mA; rail-to-rail swing. |
| 2 VEE | Negative Supply | Ground reference for input and output stages; must be connected to system GND or negative rail. |
| 3 +IN | Non-inverting Input | Differential input node with rail-to-rail common-mode range (VEE – 0.2V to VCC + 0.1V). |
| 4 –IN | Inverting Input | Differential input node; matched to +IN for <300ps skew and 51dB CMRR performance. |
| 5 VCC | Positive Supply | Powers input stage and output buffer; accepts 2.45V–3.5V; decoupling required near pin. |
| 6 LE/HYST | Latch Enable / Hysteresis Control | Configures latch mode (VIL ≤ 0.3V) or adjusts hysteresis (0–40mV range via external voltage). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range | Extends 0.2V below VEE and 0.1V above VCC - eliminates need for external level shifters in wide-VCM systems. |
| Latching with adjustable hysteresis | LE/HYST pin sets hysteresis from 5mV (floating) to 40mV (800mV applied) - prevents chatter on slow or noisy edges. |
| Low overdrive dispersion | 1.8ns variation across 10–125mV overdrive - ensures consistent timing regardless of input amplitude. |
| High CMRR & PSRR | 51dB CMRR and 59dB PSRR_VCC - rejects power supply noise and common-mode interference in dense PCB layouts. |
| Industrial temperature grade | Specified from –40°C to 125°C - validated for engine control units, motor drives, and base station RF front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP600BRMZ-REEL | Fixed 2.5ns propagation delay; no latch/hysteresis control pin; 3.3V-only supply; SC70-6 package. | Lacks LE/HYST functionality - requires external hysteresis network for noise immunity; unsuitable for latch-based sampling. | Select when fixed ultra-low delay is prioritized over configurability and wide supply range. |
| LTC6754HMS8-2#TRPBF | Dual-channel version in MSOP-8; identical specs per channel; includes shutdown pin; higher quiescent current (6.65mA vs 5.0mA). | Provides two independent comparators - ideal for dual-edge detection or window comparison without board area penalty. | Select when space-constrained designs require dual high-speed comparators with same performance envelope. |
Compared with ADCMP600BRMZ-REEL and LTC6754HMS8-2#TRPBF, the LTC6752HSC6-1#TRMPBF uniquely combines single-supply flexibility (2.45–3.5V), integrated latch/hysteresis control, and industrial temperature rating in a 6-pin SC70-making it optimal for cost-sensitive, noise-prone, and thermally demanding embedded timing functions.

FAQ
What is the maximum toggle rate supported by the LTC6752HSC6-1#TRMPBF?
The LTC6752HSC6-1#TRMPBF supports a maximum toggle rate of 280MHz under 100mVP-P input conditions with 1kΩ load to VCM. This specification is guaranteed across the full –40°C to 125°C operating temperature range and applies to the LTC6752/LTC6752-1/LTC6752-2/LTC6752-4 variants. The device maintains clean 10%–90% transitions without duty-cycle distortion at this rate.
Does the LTC6752HSC6-1#TRMPBF support separate input and output supplies?
No, the LTC6752HSC6-1#TRMPBF does not support separate input and output supplies. It is the LTC6752-1 variant, which uses a single supply (VCC to VEE) ranging from 2.45V to 3.5V. The "-1" suffix explicitly denotes the latching/adjustable hysteresis option in single-supply configuration. Separate supply versions (e.g., LTC6752-2) use different part numbers and SC70-6 pinouts with dedicated VDD and VCC pins.
How is hysteresis adjusted on the LTC6752HSC6-1#TRMPBF?
Hysteresis on the LTC6752HSC6-1#TRMPBF is adjusted via the LE/HYST pin (Pin 6). With the pin left floating, nominal hysteresis is 5mV. Applying a DC voltage between 0.8V and 1.45V scales hysteresis linearly from ~10mV to ~40mV. Voltages below 0.3V enable transparent latch mode; voltages above 1.7V disable hysteresis entirely. This adjustment is verified across temperature and supply variations.
What is the guaranteed propagation delay variation over temperature for the LTC6752HSC6-1#TRMPBF?
The LTC6752HSC6-1#TRMPBF guarantees propagation delay from 2.9ns (typical) to 5.5ns (max) over the full –40°C to 125°C operating range, measured at 50mV overdrive. Overdrive dispersion remains tightly controlled at 1.8ns maximum across 10–125mV input steps, ensuring predictable timing behavior independent of signal amplitude changes across temperature.
Can the LTC6752HSC6-1#TRMPBF operate with a 2.5V supply?
Yes, the LTC6752HSC6-1#TRMPBF is fully specified and characterized at 2.5V supply (VCC = 2.5V, VEE = 0V). Electrical parameters including 2.9ns propagation delay, 1.2ns rise/fall time, 4.5ps RMS jitter, and ±22mA output drive are all guaranteed at this voltage. The device also supports 3.3V operation with minor parameter shifts (e.g., 3.0ns typical tPD, 4.8ps jitter), maintaining full functionality across its 2.45–3.5V range.
