Product details
Overview
LTC6752ISC6-4#TRMPBF from Analog Devices is a high-speed rail-to-rail input comparator with CMOS outputs, 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, making it suitable for clock recovery, high-speed line receivers, and time-of-flight measurement circuits.
For engineers reviewing the LTC6752ISC6-4#TRMPBF datasheet, LTC6752ISC6-4#TRMPBF pinout, LTC6752ISC6-4#TRMPBF application, or LTC6752ISC6-4#TRMPBF equivalent, key selection criteria include propagation delay skew (≤600ps), overdrive dispersion (1.8ns), RMS jitter (4.5ps at 100MHz), input hysteresis (4.7–5.2mV), and SC70-6 package compatibility with 1.71V–3.5V output supply options.
Technical Context
The LTC6752ISC6-4#TRMPBF implements a differential-input, single-ended-output comparator architecture optimized for low-latency decision-making in timing-critical signal paths. Its rail-to-rail input stage supports common-mode voltages from VEE – 0.2V to VCC + 0.1V, while the CMOS output stage interfaces directly with 1.8V logic via separate VDD/VEE supplies.
This variant belongs to the LTC6752-4 subfamily: it features adjustable hysteresis via the LE/HYST pin (1.05–1.45V threshold), no shutdown function, no latch, and complementary outputs. It is specified for –40°C to 85°C operation and uses the SC70-6 package with pins Q, VEE, +IN, VCC, –IN, and LE/HYST.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 2.9ns typical (50mV overdrive); enables sub-3ns decision latency in high-frequency sampling systems. |
| Toggle Rate | 280MHz maximum; supports direct interface with >200Mbps serial data streams and fast crystal oscillator monitoring. |
| Rise/Fall Time | 1.2ns (10%–90%); ensures clean, fast edge generation for clock distribution and pulse-width discrimination. |
| Input Hysteresis | 4.7–5.2mV (LE/HYST floating); provides noise immunity without external components in noisy analog front-ends. |
| Supply Range | 2.45V–3.5V (VCC–VEE); compatible with 2.5V/3.3V systems and allows direct connection to FPGA I/O banks. |
| Output Drive | ±22mA (sourcing/sinking); drives 50Ω transmission lines or fan-out to multiple CMOS inputs without buffers. |
| RMS Jitter | 4.5ps (100MHz input, 10Hz–50MHz BW); meets stringent timing budget requirements in SERDES and ADC clocking. |
Pinout & Package
Package: 6-lead plastic SC70 (SC6), 2.0mm × 1.25mm, 0.65mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Q | CMOS Output | Active-high digital output; swings rail-to-rail between VDD and VEE (or VCC and VEE for single-supply config). |
| 2 - VEE | Negative Supply | Ground reference for both 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; bias current < ±4.2µA across temperature. |
| 4 - VCC | Positive Input Supply | Powers input stage only; supports 2.45V–3.5V; PSRR ≥53dB reduces sensitivity to power noise. |
| 5 - –IN | Inverting Input | Differential input node; matched impedance (RDM = 57kΩ, RCM = 6.4MΩ) ensures high CMRR (≥50dB). |
| 6 - LE/HYST | Hysteresis Control | Analog-adjustable hysteresis pin; 0.8V sets ~40mV hysteresis; open-circuit defaults to 4.7–5.2mV. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input Stage | Operates with inputs extending 200mV beyond rails (VEE – 0.2V to VCC + 0.1V), enabling direct sensing of signals near supply boundaries. |
| Adjustable Input Hysteresis | LE/HYST pin accepts 0–1.45V to scale hysteresis from 5mV to 40mV, eliminating need for external feedback resistors. |
| Low Overdrive Dispersion | 1.8ns variation across 10–125mV overdrive ensures consistent timing margins in amplitude-varying signal paths. |
| High Common-Mode Rejection | CMRR ≥50dB across full input range suppresses noise coupling in differential signaling environments like LVDS receivers. |
| Ultra-Low Propagation Skew | 600ps max skew between rising/falling transitions preserves duty-cycle integrity in clock regeneration applications. |

FAQ
What is the supply voltage range for LTC6752ISC6-4#TRMPBF?
The LTC6752ISC6-4#TRMPBF operates from a single 2.45V to 3.5V supply across VCC and VEE. It does not support separate input/output supplies (unlike LTC6752-2/3 variants). This range ensures compatibility with standard 2.5V and 3.3V systems while maintaining rail-to-rail input operation down to 2.45V.
Does LTC6752ISC6-4#TRMPBF support adjustable hysteresis, and how is it configured?
Yes, LTC6752ISC6-4#TRMPBF supports adjustable hysteresis via its LE/HYST pin (Pin 6). Applying 0.8V to this pin sets hysteresis to ~40mV; leaving it open yields 4.7–5.2mV. The pin's voltage threshold (1.05–1.45V) and internal resistance (15–25kΩ) allow precise analog tuning without external components-critical for noise-sensitive sensor interfaces.
What is the propagation delay specification for LTC6752ISC6-4#TRMPBF, and how does overdrive affect it?
LTC6752ISC6-4#TRMPBF has a typical propagation delay of 2.9ns at 50mV overdrive, with a maximum of 5.5ns across temperature. Its overdrive dispersion is tightly controlled at 1.8ns (10–125mV), meaning delay variation remains under 2ns regardless of input step size-ensuring predictable timing in amplitude-variable signal chains.
Can LTC6752ISC6-4#TRMPBF drive 50Ω transmission lines directly?
Yes, LTC6752ISC6-4#TRMPBF delivers ±22mA output current, enabling direct 50Ω line driving with <1.2ns edge rates. When terminated properly, it achieves clean 1Vpp CMOS swings into 50Ω loads-eliminating need for external buffers in high-speed interconnects such as FPGA clock distribution or test probe interfaces.
Is LTC6752ISC6-4#TRMPBF pin-compatible with other SC70-6 comparators like ADCMP600 series?
No, LTC6752ISC6-4#TRMPBF is not pin-compatible with ADCMP600-series SC70-6 comparators. Its pinout (Q, VEE, +IN, VCC, –IN, LE/HYST) differs from ADCMP600's (OUT, –IN, +IN, VDD, VSS, EN). Layout reuse requires redesign; however, functional equivalents exist with different footprints-always verify pin mapping before PCB integration.
