Product details
Overview
TLV3605RVKT from Texas Instruments is a single-channel, 800ps high-speed rail-to-rail input comparator with LVDS outputs, operating from 2.4V to 5.5V supply rails. It delivers ±5mV input offset voltage, 350ps overdrive dispersion, and 600ps minimum detectable pulse width-enabling precise timing in LIDAR front-ends and test equipment trigger paths.
For engineers reviewing the TLV3605RVKT datasheet, TLV3605RVKT pinout, TLV3605RVKT application, or TLV3605RVKT equivalent, this device is selected for ultra-low propagation delay consistency, differential output noise immunity, and direct interface capability with high-speed FPGAs and clock recovery ICs in optical sensing and instrumentation systems.
Technical Context
The TLV3605RVKT implements a fully differential LVDS output stage with 100Ω internal termination support, delivering ±350mV swing into standard 100Ω loads while suppressing common-mode EMI. Its rail-to-rail input stage extends 200mV beyond both VEE and VCCI rails, enabling zero-crossing detection without level-shifting circuitry.
It integrates adjustable hysteresis (0–60mV via external resistor) and active-low shutdown (SHDN), with latch enable (LE/HYS) supporting hold functionality for stable edge capture in oscilloscope trigger circuits. Propagation delay skew between channels is not applicable (single-channel), but tPD_SKEW is specified at 40ps for output pair matching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 800ps typical - enables sub-nanosecond timing resolution in time-of-flight distance measurement |
| Overdrive dispersion | 350ps max - ensures consistent timing across varying input signal amplitudes in pulsed LIDAR receivers |
| Input offset voltage | ±5mV max - supports accurate threshold detection in low-amplitude analog front-ends |
| Supply range | 2.4V to 5.5V - compatible with 2.5V, 3.3V, and 5V logic domains without level translation |
| LVDS output swing | 250–450mV differential - meets ANSI/TIA/EIA-644 LVDS standard for direct FPGA/CPU interfacing |
| Minimum pulse width | 600ps - allows detection of narrow optical return pulses in high-resolution LIDAR systems |
| Quiescent current | 12.1mA typical - balances speed and power in battery-constrained portable test instruments |
Pinout & Package
TLV3605RVKT is housed in a 12-pin QFN (RVK) package, 3.00mm × 3.00mm body size, with exposed thermal pad for enhanced thermal performance in compact optical modules and PCB space-constrained instrumentation designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Non-inverting input | Rail-to-rail analog input accepting signals from VEE – 0.2V to VCCI + 0.2V |
| IN− | Inverting input | Differential input pair with matched impedance and low capacitance (1pF) |
| OUT+ | Non-inverting LVDS output | Active-high LVDS output referenced to VCCO; requires 100Ω termination to VCCO/2 |
| OUT− | Inverting LVDS output | Complementary LVDS output; together with OUT+ forms noise-immune differential signaling |
| VEE | Negative supply | Common ground or negative rail; shared across pins 3, 5, 9, 11 for low-impedance return path |
| VCCI | Positive input supply | Separate 2.4–5.5V rail for input stage; decoupling required near pin 2 |
| VCCO | Positive output supply | Separate 2.4–5.5V rail for LVDS output stage; independent of VCCI for supply noise isolation |
| SHDN | Shutdown control | Active-low logic input; 1.8V-compatible; reduces ICC to 1.5mA input + 100μA output in sleep mode |
| LE/HYS | Latch enable / hysteresis control | Configures latching (active-low) or adjusts hysteresis (0–60mV) via external resistor to VEE |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates 200mV beyond both supply rails - eliminates need for external biasing in AC-coupled sensor interfaces |
| LVDS output compliance | Meets ANSI/TIA/EIA-644 standard with ±350mV swing - enables direct connection to Xilinx/Kintex or Intel/Arria FPGA transceivers |
| Adjustable hysteresis | 0–60mV via single external resistor - suppresses false triggering on noisy inputs without redesigning feedback networks |
| Low-overdrive dispersion | 350ps max variation - maintains timing accuracy across weak and strong optical return signals in ToF systems |
| Fast wake-up time | 100ns from shutdown - supports burst-mode operation in power-sensitive portable LIDAR units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3604DCKR | 6-pin SC70 package; no SHDN or LE/HYS pins; fixed hysteresis only via external feedback | Suitable for space-constrained optical modules where latch/shutdown not required | Choose TLV3604DCKR when board area is critical and system-level hysteresis control suffices |
| LMH7322MA/NOPB | 2.7V–12.6V supply; 1.8ns propagation delay; PECL output; no rail-to-rail input | Better suited for wide-supply industrial systems requiring higher voltage tolerance and PECL compatibility | Choose LMH7322MA/NOPB when interfacing with legacy PECL logic or operating above 5.5V |
Compared with TLV3605RVKT, TLV3604DCKR saves board space but sacrifices configurability, while LMH7322MA/NOPB offers wider supply range and PECL drive at the cost of slower timing and reduced input flexibility-making TLV3605RVKT optimal for LVDS-centric, low-jitter, rail-to-rail LIDAR and test equipment designs.

FAQ
What is the maximum toggle frequency supported by the TLV3605RVKT?
The TLV3605RVKT supports a maximum input toggle frequency of 1.5GHz and a 3.0Gbps data rate under typical conditions (200mVPP sine input, 50% output swing). This performance is sustained across its full operating temperature range (–40°C to +125°C) and supply range (2.4V to 5.5V), making it suitable for high-speed serial link monitoring and clock recovery applications where deterministic timing is essential.
Does the TLV3605RVKT require external termination resistors for its LVDS outputs?
No-the TLV3605RVKT LVDS outputs are designed to drive standard 100Ω differential loads directly. The device expects an external 100Ω termination resistor placed across OUT+ and OUT– at the receiving end (e.g., FPGA LVDS input), not on the TLV3605RVKT side. Internal output drivers comply with ANSI/TIA/EIA-644 LVDS specifications, delivering 250–450mV differential swing into that load without additional series resistors.
How does the LE/HYS pin function in the TLV3605RVKT?
The LE/HYS pin on the TLV3605RVKT serves dual roles: when pulled below 0.35V (relative to VEE), it enables latch mode, freezing the output state until the pin is released; when biased with a resistor to VEE (150kΩ → 30mV hysteresis; 56kΩ → 60mV), it configures adjustable input hysteresis to prevent chatter on slow or noisy inputs. Both functions operate independently of supply voltage and remain functional across the full –40°C to +125°C temperature range.
Can the TLV3605RVKT operate with separate input and output supply rails?
Yes-the TLV3605RVKT features independent VCCI (input stage supply) and VCCO (output stage supply) pins, each rated for 2.4V to 5.5V. This separation allows optimization of noise isolation: VCCI can be powered from a clean analog rail while VCCO connects to a dedicated low-noise digital supply, minimizing coupling between sensitive input circuitry and high-speed LVDS switching transients-critical in mixed-signal LIDAR receiver designs.
What is the thermal performance of the TLV3605RVKT in its QFN package?
The TLV3605RVKT in the 12-pin RVK QFN package has a junction-to-ambient thermal resistance (RθJA) of 85.8°C/W and a junction-to-board resistance (RθJB) of 52.7°C/W. With its exposed thermal pad soldered to a 4-layer PCB with ≥2 cm² copper pour, it sustains continuous 12.1mA operation at +125°C ambient-validated per TI's SNOSDA2F datasheet. This enables reliable deployment in sealed optical enclosures without forced airflow.
