Product details
Overview
TLV3604DCKT from Texas Instruments is a single-channel, 800ps propagation delay, rail-to-rail input comparator with LVDS differential outputs, operating from 2.4V to 5.5V supply, delivering ±350mV output swing into 100Ω and detecting 600ps input pulses - deployed in LIDAR front-ends and high-speed optical time-of-flight sensors.
For engineers reviewing the TLV3604DCKT datasheet, TLV3604DCKT pinout, TLV3604DCKT application, or TLV3604DCKT equivalent, key selection criteria include sub-nanosecond timing precision, LVDS interface compatibility with FPGAs/CPUs, rail-to-rail input operation beyond supply rails by ±200mV, and SC-70 package suitability for space-constrained optical modules.
Technical Context
The TLV3604DCKT implements a high-gain, low-offset comparator core with dedicated input and output supply domains (VCCI/VCCO), enabling independent optimization of input dynamic range and LVDS output drive. Its rail-to-rail input stage supports common-mode voltages from VEE − 200mV to VCCI + 200mV, while the LVDS output stage delivers fast toggle rates up to 3.0Gbps with matched rise/fall times of 350ps.
Unlike the TLV3605/TLV3607 variants, the TLV3604DCKT lacks shutdown, latch, or adjustable hysteresis control pins - it operates in a single functional mode with fixed internal hysteresis and no external control interfaces, simplifying integration where minimal feature set and smallest footprint are prioritized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 800ps typical - enables precise time-of-flight measurement resolution down to ~12 cm in LIDAR systems. |
| Overdrive dispersion | 350ps maximum - ensures consistent timing across varying input signal amplitudes, critical for pulse-width discrimination. |
| Supply voltage range | 2.4V to 5.5V - supports direct interfacing with 2.5V, 3.3V, and 5V logic and analog subsystems without level-shifting. |
| Input common-mode range | VEE − 200mV to VCCI + 200mV - allows zero-crossing detection and maximizes usable input dynamic range. |
| Differential output swing | ±350mV into 100Ω - meets LVDS standard compliance and ensures robust noise margin when driving FPGA LVDS inputs. |
| Quiescent current | 12.1mA typical at 2.5–5V - balances ultra-high speed with moderate power consumption for portable or thermally constrained designs. |
| Minimum detectable pulse width | 600ps - supports high-resolution optical pulse discrimination in drone vision and laser ranging applications. |
Pinout & Package
The TLV3604DCKT is housed in a 6-pin SC-70 (DCK) package measuring 1.25mm × 2.00mm, optimized for compact optical sensor modules and PCB area-sensitive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT+ | Non-inverting LVDS output | Drives positive side of differential LVDS bus; requires 100Ω termination to VCCO for standard swing. |
| IN− | Inverting input | Accepts rail-to-rail differential or single-ended signals; common-mode range extends ±200mV beyond supplies. |
| OUT− | Inverting LVDS output | Complements OUT+; differential pair suppresses common-mode EMI and improves signal integrity. |
| VEE | Negative power supply | Reference for both input and output stages; may be connected to ground or negative rail depending on system architecture. |
| IN+ | Non-inverting input | Primary signal input node; paired with IN− for differential sensing or used alone with reference on IN−. |
| VCCI/VCCO | Positive supply (shared input/output) | Single supply pin powers both input and output sections; simplifies layout but couples supply noise between domains. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Supports input voltages 200mV beyond VEE and VCCI - enables direct connection to photodiode transimpedance amplifier outputs without clamping or level shift. |
| LVDS differential outputs | Delivers 350mV swing into 100Ω load with 350ps rise/fall times - ensures clean, low-jitter digital transitions compatible with Xilinx/Intel FPGA LVDS receivers. |
| 800ps propagation delay | Fixed, low-latency response across temperature and supply - critical for deterministic timing in time-of-flight distance measurement circuits. |
| 600ps minimum pulse width detection | Validates ability to resolve ultra-short optical pulses in high-speed LIDAR return signals, extending maximum measurable range. |
| 2.4V to 5.5V single-supply operation | Eliminates need for dual supplies or charge pumps - reduces BOM count and simplifies power delivery in embedded optical modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3605RVKT | 12-pin QFN; adds shutdown, latch enable, and adjustable hysteresis control pins; identical 800ps delay and LVDS output specs. | Required where dynamic power gating, output state hold, or noise-immune threshold adjustment is needed - e.g., programmable test fixtures. | Select TLV3605RVKT only if control features justify larger footprint and added complexity; TLV3604DCKT remains optimal for fixed-function, space-limited use cases. |
| ADCMP572BCPZ-R7 | 5.5ns propagation delay; PECL output; 3.3V-only supply; higher quiescent current (35mA); no rail-to-rail input. | Suitable for legacy PECL systems or where longer delay is acceptable; not interchangeable due to incompatible output standard and supply constraints. | Choose ADCMP572BCPZ-R7 only for existing PECL infrastructure; TLV3604DCKT provides superior speed, LVDS compatibility, and wider supply range for new designs. |
Compared with TLV3605RVKT, TLV3604DCKT offers identical speed and LVDS performance in half the package size but lacks configurability; compared with ADCMP572BCPZ-R7, it delivers 7× faster propagation, LVDS instead of PECL, and broader supply support - making it the preferred choice for modern high-density, low-jitter optical and test systems.

FAQ
What is the propagation delay specification for TLV3604DCKT?
The TLV3604DCKT has a typical propagation delay of 800ps under standard test conditions (50mV overdrive, 50MHz square wave). This value is confirmed across temperature (–40°C to +125°C) and supply voltage (2.5V to 5V) in the official datasheet, enabling precise timing in LIDAR and time-of-flight applications where nanosecond-level accuracy is essential. TLV3604DCKT maintains this performance without requiring external calibration or trimming.
Does TLV3604DCKT support rail-to-rail input operation?
Yes, TLV3604DCKT supports rail-to-rail input operation with a common-mode voltage range extending 200mV beyond both supply rails (VEE − 200mV to VCCI + 200mV). This capability is explicitly verified in the datasheet's Electrical Characteristics table and enables direct interfacing with transimpedance amplifiers and other signal sources operating near supply limits - a key advantage of TLV3604DCKT in optical front-end designs.
What output standard does TLV3604DCKT implement?
TLV3604DCKT implements a fully compliant Low-Voltage Differential Signaling (LVDS) output stage, delivering ±350mV differential swing into a 100Ω load. The datasheet confirms LVDS compatibility, including rise/fall times of 350ps and common-mode voltage of 1.2V, ensuring seamless interoperability with FPGA, ASIC, and processor LVDS input receivers without additional level-shifting circuitry - a defining feature of TLV3604DCKT.
Is TLV3604DCKT pin-compatible with TLV3605 or TLV3607?
No, TLV3604DCKT is not pin-compatible with TLV3605 or TLV3607. TLV3604DCKT uses a 6-pin SC-70 (DCK) package with no control pins, while TLV3605 (12-pin QFN) and TLV3607 (16-pin WQFN) include dedicated SHDN, LE/HYS, and dual-channel routing. The pin functions, counts, and physical layouts differ fundamentally - TLV3604DCKT is a purpose-built minimal variant, and TLV3604DCKT PCB footprints cannot accommodate either alternative without redesign.
What is the quiescent current consumption of TLV3604DCKT?
TLV3604DCKT draws a typical quiescent current of 12.1mA at VCCI = VCCO = 2.5V to 5V and TA = 25°C, with a maximum of 16.5mA across temperature and voltage extremes. This value is measured and specified in Section 5.5 of the datasheet under "ICC (TLV3604) Total quiescent current", confirming TLV3604DCKT's balance of ultra-high speed and moderate power efficiency for battery-sensitive or thermally constrained optical modules.
