Product details
Overview
LTC6754ISC6#TRMPBF from Analog Devices (formerly Linear Technology) is a high-speed rail-to-rail input comparator with LVDS-compatible differential outputs in a 6-lead SC70 package. It delivers 1.8ns typical propagation delay, 1ns overdrive dispersion (10mV–125mV), 890Mbps toggle rate, and operates from 2.4V to 5.25V supply. It is used in clock/data recovery circuits where precise timing and low jitter are critical.
For engineers reviewing the LTC6754ISC6#TRMPBF datasheet, LTC6754ISC6#TRMPBF pinout, LTC6754ISC6#TRMPBF application, or LTC6754ISC6#TRMPBF equivalent, key selection considerations include its LVDS output compliance, shutdown wake-up time (120ns), adjustable hysteresis capability (4.5mV default), rail-to-rail input range extending beyond both rails, and SC70 footprint compatibility with space-constrained high-frequency PCB layouts.
Technical Context
The LTC6754ISC6#TRMPBF implements a dual-stage architecture: a rail-to-rail input stage with PNP/NPN composite front-end enabling operation across VEE – 0.2V to VCCI + 0.1V, followed by a gain stage and LVDS output driver. Its separate VCCI/VCCO pins are internally tied in the SC70 variant, eliminating level translation but retaining low-noise isolation design intent.
It features integrated hysteresis (4.5mV typ., adjustable via external resistor on LE/HYST in QFN variants), active-low shutdown (1.05mA total current in shutdown), and output latching functionality-though latching is not available in the SC70 package due to pin count limitation (no dedicated LE/HYST or SHDN pins).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.8ns typical at 50mV overdrive - enables sub-nanosecond timing resolution in sampling and edge-detection systems. |
| Overdrive Dispersion | 1ns typical (10mV–125mV) - ensures consistent timing across varying signal amplitudes, critical for jitter-sensitive clock recovery. |
| Toggle Rate | 890Mbps typical - supports high-speed serial data acquisition and line receiver applications up to ~445MHz fundamental frequency. |
| Supply Range | 2.4V to 5.25V - compatible with 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Offset Voltage | ±0.75mV max - provides high DC accuracy for precision threshold detection in window comparators. |
| RMS Jitter | 1.5ps at 245.76MHz (10Hz–122.88MHz BW) - meets stringent phase noise requirements in telecom and instrumentation clock paths. |
| Output Common Mode | 1.26V typical - matches standard LVDS receiver common-mode input range (1.12V–1.26V) for direct interface. |
Pinout & Package
Package: 6-lead plastic SC70 (SC6), 2.2mm × 1.35mm × 0.95mm body, exposed pad not present. Pin pitch: 0.65mm. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q) | Positive LVDS Output | Differential output sourcing/sinking 3.6mA into 100Ω load; swings VOCM ± VOD/2 (≈1.26V ± 180mV at 5V). |
| 2 (VEE) | Negative Supply Rail | Reference ground for both input and output stages; must be connected to system ground or negative bias rail. |
| 3 (+IN) | Non-inverting Input | Rail-to-rail capable: accepts signals from VEE – 0.2V to VCCI + 0.1V; supports wide common-mode input in high-speed receivers. |
| 4 (–IN) | Inverting Input | Matches +IN in voltage range and bias behavior; differential pair enables rejection of common-mode noise up to 77dB. |
| 5 (VCCI/VCCO) | Combined Input/Output Supply | Single 2.4V–5.25V supply powers both input and LVDS output stages in SC70 package; no isolation between domains. |
| 6 (Q) | Negative LVDS Output | Complementary to Pin 1; forms true differential LVDS pair meeting ANSI/TIA/EIA-644-A electrical specifications. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts inputs beyond supply rails (VEE – 0.2V to VCCI + 0.1V), enabling direct interface with AC-coupled or overvoltage-tolerant sources. |
| LVDS-compatible outputs | Delivers 360mV differential swing and 1.26V common mode onto 100Ω termination - compliant with industry-standard LVDS receivers. |
| Low propagation delay skew | 50ps Q-to-Q skew ensures matched rising/falling edge alignment critical for clock distribution and time-of-flight measurement. |
| Hysteresis (4.5mV typ.) | Reduces output oscillation near threshold in noisy environments; fixed value in SC70 variant (no external adjustment pin). |
| Shutdown mode | Reduces total supply current to 1.05mA (typ.), enabling power gating in battery-operated or burst-mode systems. |
Applications
| Clock and Data Recovery | High-Speed Line Receiver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP600BRJZ-REEL7 | CMOS output (not LVDS); 1.5ns propagation delay; 2.7V–5.5V supply; no hysteresis; SC70-6 package. | Requires external LVDS translator for interface with LVDS receivers; better suited for single-ended logic interfacing. | Select when LVDS output is unnecessary and lower quiescent current (5.5mA vs 13.4mA) is prioritized over differential noise immunity. |
| TLV3501DBVR | Push-pull CMOS output; 4.5ns propagation delay; 2.7V–5.5V supply; 3mV hysteresis; SOT-23-6 package. | Slower timing performance limits use in >500Mbps systems; lacks LVDS drive strength and common-mode rejection. | Select for cost-sensitive, non-LVDS applications below 300Mbps where board space allows SOT-23 and jitter tolerance >5ps is acceptable. |
Compared with ADCMP600BRJZ-REEL7 and TLV3501DBVR, the LTC6754ISC6#TRMPBF uniquely combines LVDS compliance, sub-2ns delay, and rail-to-rail input in SC70 - making it the only option among the three suitable for direct integration into high-speed serial link receivers without additional level-shifting circuitry.

FAQ
What is the maximum operating temperature range for the LTC6754ISC6#TRMPBF?
The LTC6754ISC6#TRMPBF is specified for operation from –40°C to +85°C (Industrial grade). Its absolute maximum junction temperature is 150°C, and thermal resistance θJA is 256°C/W in the SC70 package. Derating is required above 85°C ambient unless heatsinking is implemented.
Does the LTC6754ISC6#TRMPBF support adjustable hysteresis?
No - the LTC6754ISC6#TRMPBF uses the fixed-hysteresis SC70 variant. Hysteresis is trimmed to 4.5mV (typ.) and cannot be adjusted externally. Adjustable hysteresis requires the QFN package (e.g., LTC6754IUD#PBF) with dedicated LE/HYST pin.
Can the LTC6754ISC6#TRMPBF be used with a single 3.3V supply?
Yes - the LTC6754ISC6#TRMPBF operates from 2.4V to 5.25V. At 3.3V supply, it delivers 1.25V common-mode output and ~345mV differential swing (typ.), remaining fully compliant with LVDS receiver input thresholds and maintaining 1.8ns propagation delay.
Is the LTC6754ISC6#TRMPBF pin-compatible with other SC70 comparators?
No - the LTC6754ISC6#TRMPBF has a unique SC70-6 pinout optimized for LVDS outputs (Q/Q on Pins 1/6, +IN/–IN on Pins 3/4). It is not pin-compatible with generic SC70 comparators like LT1719 or ADCMP600, which assign different functions to Pin 5 (e.g., VREF, DIS, or GND).
What is the shutdown wake-up time for the LTC6754ISC6#TRMPBF?
The LTC6754ISC6#TRMPBF wakes up from shutdown in 120ns (typ.) with valid output, measured at 100mV overdrive. This enables rapid power cycling in burst-mode systems such as time-of-flight sensors or packet-based communication receivers.
