Product details
Overview
LTC6754ISC6#TRPBF 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 (10–125mV), 890Mbps toggle rate, and operates from 2.4V to 5.25V supply. It is used in timing-critical clock/data recovery circuits where low jitter (1.5psRMS at 245.76MHz) and precise edge detection are essential.
For engineers reviewing the LTC6754ISC6#TRPBF datasheet, LTC6754ISC6#TRPBF pinout, LTC6754ISC6#TRPBF application, or LTC6754ISC6#TRPBF equivalent, this page provides verified specifications, SC70 package terminal mapping, real-world use cases in high-speed line receivers and time-of-flight systems, and two validated alternative comparators with documented functional trade-offs.
Technical Context
The LTC6754ISC6#TRPBF integrates a rail-to-rail input stage composed of complementary PNP/NPN pairs enabling operation beyond both supply rails (VEE −0.2V to VCCI +0.1V), followed by a gain stage and an LVDS output driver with common-mode feedback maintaining VOCM ≈1.26V. Its dual-supply architecture (VCCI/VCCO) is internally tied in the SC70 variant, simplifying layout but eliminating independent input/output voltage scaling.
It features fixed 4.5mV hysteresis (LE/HYST pin unconnected), shutdown mode reducing total current to 1.05mA, and wake-up time of 120ns. Propagation delay skew between Q and Q outputs is 50ps, and rise/fall times are 0.77ns (20%–80%), supporting deterministic timing in high-frequency sampling and serial link monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.8ns typ. at 50mV overdrive - enables sub-2ns timing resolution in clock recovery and TDR systems. |
| Overdrive Dispersion | 1ns typ. (10–125mV) - ensures consistent decision timing across varying signal amplitudes. |
| Toggle Rate | 890Mbps typ. - supports high-speed serial data acquisition up to ~445MHz fundamental frequency. |
| LVDS Output Swing | 362mV diff. (VOD), 1.26V common-mode (VOCM) - compliant with ANSI/TIA/EIA-644 LVDS standard for point-to-point interconnects. |
| Supply Range | 2.4V to 5.25V (VCCI = VCCO) - allows direct interface with 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Offset Voltage | ±0.75mV max - supports accurate threshold detection in precision window comparators and analog front-ends. |
| Shutdown Current | 1.05mA typ. - reduces power by >92% vs active mode (13.4mA), critical for burst-mode instrumentation. |
Pinout & Package
Package: 6-lead SC70 (SC6), 2.0mm × 1.25mm × 0.9mm body, moisture sensitivity level 1, Pb-free (RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q) | Positive LVDS Output | Drives high when +IN > –IN; swings VOCM ± VOD/2 across 100Ω load; requires termination to VCCO/2 for LVDS compliance. |
| 2 (VEE) | Negative Supply | Reference ground for both input and output stages; must be connected directly to PCB ground plane for noise immunity. |
| 3 (+IN) | Non-inverting Input | Rail-to-rail capable (VEE −0.2V to VCCI +0.1V); accepts differential or single-ended signals; bias current < ±2.5µA. |
| 4 (–IN) | Inverting Input | Matched to +IN; differential input resistance 55kΩ; common-mode rejection >58dB across full VCM range. |
| 5 (VCCI/VCCO) | Combined Input/Output Supply | Single 2.4–5.25V supply powers both stages in SC70; eliminates need for separate VCCO bypassing required in QFN version. |
| 6 (Q) | Negative LVDS Output | Complementary to Pin 1; forms true differential pair; unused pins must not be left floating - terminate or tie to defined state. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates with inputs extending 0.2V below VEE and 0.1V above VCCI - enables direct sensing of signals near supply rails in sensor interfaces. |
| LVDS-compatible outputs | Delivers 362mV differential swing and 1.26V common-mode voltage into 100Ω - ensures interoperability with FPGA transceivers and SERDES PHYs. |
| Low overdrive dispersion | 1ns variation across 10–125mV overdrive - preserves timing integrity in variable-amplitude data streams like PRBS patterns. |
| Fast wake-up from shutdown | 120ns transition to valid output - supports low-duty-cycle sampling in portable test equipment and battery-powered TDR probes. |
| Integrated hysteresis | 4.5mV fixed (pin floating) - suppresses chatter on slow or noisy inputs without external components in industrial control thresholds. |

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; no integrated hysteresis; 2.7–5.5V supply. | Requires external termination and level-shifting for LVDS systems; better suited for driving FPGAs with CMOS inputs. | Select when interfacing with non-LVDS logic and lower power (5.5mA) is prioritized over differential noise immunity. |
| TLV3501CDCKR | Push-pull CMOS output; 4.5ns propagation delay; rail-to-rail input; 2.7–5.5V supply; no shutdown. | Lacks LVDS drive strength and jitter performance; unsuitable for >500Mbps serial links. | Choose for cost-sensitive, lower-speed (<300Mbps) applications where board space is constrained and LVDS compliance is unnecessary. |
Compared with ADCMP600BRJZ-REEL7 and TLV3501CDCKR, the LTC6754ISC6#TRPBF uniquely combines LVDS output compliance, sub-2ns delay, and integrated hysteresis in SC70 - making it irreplaceable in timing-critical, noise-prone serial data paths requiring guaranteed differential signaling.

FAQ
What is the maximum operating temperature range for the LTC6754ISC6#TRPBF?
The LTC6754ISC6#TRPBF 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 per Linear's layout guidelines.
Does the LTC6754ISC6#TRPBF require external hysteresis resistors?
No. The LTC6754ISC6#TRPBF provides 4.5mV of internal hysteresis when the LE/HYST pin is left unconnected. This fixed hysteresis is sufficient for most noise-immune threshold detection tasks. The LE/HYST pin is not brought out in the SC70 package, so hysteresis adjustment or latching is unavailable in this variant.
Can the LTC6754ISC6#TRPBF drive a 100Ω differential load directly?
Yes. The LTC6754ISC6#TRPBF is designed to drive a 100Ω termination resistor placed across Q and Q outputs. With VCCI = VCCO = 5V, it delivers 362mV differential output voltage (VOD) and 1.26V common-mode voltage (VOCM), meeting ANSI/TIA/EIA-644 LVDS specifications without external components.
Is the LTC6754ISC6#TRPBF pin-compatible with other members of the LTC6754 family?
No. The LTC6754ISC6#TRPBF uses the 6-pin SC70 package with VCCI and VCCO internally tied. In contrast, the QFN variants (e.g., LTC6754IUD#TRPBF) have 12 pins, separate VCCI/VCCO supplies, LE/HYST and SHDN pins, and different pinouts. Direct PCB replacement is not possible without layout revision.
What is the shutdown behavior of the LTC6754ISC6#TRPBF?
The LTC6754ISC6#TRPBF enters shutdown when the SHDN pin is pulled low (<0.8V). Total supply current drops to 1.05mA, outputs go high-impedance, and wake-up time to valid output is 120ns. SHDN is internally pulled up; leaving it unconnected keeps the device fully operational.
