Product details
Overview
TLV3601DCKT from Texas Instruments is a single-channel, 325 MHz high-speed comparator with 2.5 ns propagation delay, rail-to-rail inputs extending 200 mV beyond both supply rails, ±5 mV input offset voltage, and push-pull output. It operates from 2.4 V to 5.5 V and is used in laser distance meters and LIDAR time-of-flight signal conditioning.
For engineers reviewing the TLV3601DCKT datasheet, TLV3601DCKT pinout, TLV3601DCKT application, or TLV3601DCKT equivalent, this page delivers verified electrical specs, SC70-5 package details, functional safety documentation status, thermal metrics, and real-world use context for narrow-pulse detection and clock/data recovery designs.
Technical Context
The TLV3601DCKT implements a high-gain, low-latency analog comparator core with fully differential input stage and push-pull output driver. Its 2.5 ns propagation delay (typical at 50 mV overdrive) and 1.25 ns minimum detectable pulse width are achieved via optimized internal biasing and low-capacitance node design.
It supports wide common-mode range (VEE – 0.2 V to VCC + 0.2 V), exhibits 600 ps overdrive dispersion, and maintains stable operation across –40°C to +125°C ambient temperature. No hysteresis control or latch function is present-those features are exclusive to TLV3603(E) variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5 ns typical (50 mV overdrive); enables sub-nanosecond timing resolution in TOF systems |
| Toggle frequency | 325 MHz maximum; supports high-speed serial data sampling and clock recovery |
| Input offset voltage | ±5 mV max (–40°C to +125°C); ensures accurate threshold detection without calibration |
| Supply voltage range | 2.4 V to 5.5 V; compatible with 2.5 V, 3.3 V, and 5 V logic domains |
| Input common-mode range | VEE – 0.2 V to VCC + 0.2 V; allows direct interface to signals exceeding supply rails |
| Output type | Push-pull (single-ended); eliminates need for external pull-up resistors and reduces power vs. open-drain |
| Quiescent current | 4.9–7 mA (–40°C to +125°C); balances speed and power in battery-sensitive applications |
Pinout & Package
TLV3601DCKT is packaged in a 5-pin SC70 (DCK) package with nominal body size 1.25 mm × 2.00 mm and 0.65 mm pitch. The package is moisture-sensitive level 1 (MSL-1), RoHS-compliant, and suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Output | Push-pull digital output; drives CMOS/TTL loads directly without external components |
| 2: VEE | Negative supply | Ground or negative rail reference; must be connected for proper biasing of input stage |
| 3: IN+ | Non-inverting input | Differential input node with rail-to-rail common-mode range and 1 pF input capacitance |
| 4: IN– | Inverting input | Differential input node matched to IN+; supports fast edge detection with minimal skew |
| 5: VCC | Positive supply | Primary power rail; supplies internal bias and output driver; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates 200 mV beyond VEE and VCC rails-enables direct sensing of signals outside supply domain |
| 2.5 ns propagation delay | Guaranteed <4.5 ns max over full temperature range; critical for sub-ns timing accuracy in LIDAR |
| 600 ps overdrive dispersion | Minimizes timing jitter across varying input amplitudes-essential for consistent pulse-width measurement |
| 1.25 ns minimum pulse width | Supports detection of ultra-short optical return pulses in high-resolution time-of-flight systems |
| Functional safety documentation | TI provides FIT rate, failure mode analysis, and diagnostic coverage reports for ISO 26262/IEC 61508 compliance |
Applications
| Laser Distance Meter | High-Speed Oscilloscope Trigger |
|---|---|
Use Scenario: Measures round-trip time of pulsed laser light reflected from target surfaces to compute distance with mm-level precision. IC Role / Device Role / Timing Role: Comparator captures leading edge of weak, fast-return photodiode signal; converts analog pulse to clean digital timing edge. Use Value: 2.5 ns propagation delay and 1.25 ns minimum pulse width enable <10 cm resolution at 100 MHz system clock. | Use Scenario: Generates precise trigger events on fast transient signals (e.g., glitches, edges) for oscilloscope acquisition. IC Role / Device Role / Timing Role: High-speed comparator detects crossing of input signal against programmable threshold; outputs synchronous trigger pulse. Use Value: 325 MHz toggle frequency and low overdrive dispersion ensure reliable triggering on 100+ MHz edges with sub-ns jitter. |
| LIDAR Time-of-Flight Receiver | High-Speed Differential Line Receiver |
Use Scenario: Converts weak, nanosecond-scale avalanche photodiode (APD) pulses into digital timing markers for 3D point cloud generation. IC Role / Device Role / Timing Role: Front-end comparator conditions low-amplitude, high-bandwidth return pulses before TDC or FPGA timestamping. Use Value: Rail-to-rail inputs accept APD signals referenced to ground or negative bias; push-pull output drives FPGA I/O directly. | Use Scenario: Receives high-frequency differential data streams (e.g., LVDS, PECL) and converts them to single-ended CMOS logic for processor interfacing. IC Role / Device Role / Timing Role: Single-ended comparator reconstructs logic state from differential pair using one leg as reference and the other as signal. Use Value: Wide 2.4–5.5 V supply range allows compatibility with multiple logic families; 2.5 ns delay preserves signal integrity up to 325 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3601DBVT | Same electrical specs and functionality; packaged in 5-pin SOT-23 (2.90 mm × 1.60 mm), larger footprint than SC70 | Suitable for less space-constrained PCBs where thermal performance (RθJA = 176.5°C/W) is prioritized over miniaturization | Select TLV3601DBVT when board area permits and higher power dissipation margin is needed. |
| TLV3603DCKR | Includes LE/HYST pin for adjustable hysteresis and latch mode; 6-pin SC70; otherwise identical speed, delay, and supply specs | Required when noise immunity (via external resistor hysteresis) or output state retention (latch) is needed in the signal path | Choose TLV3603DCKR only if hysteresis control or latching is explicitly required-adds complexity and pin count. |
Compared with TLV3601DCKT, TLV3601DBVT offers better thermal resistance but larger layout footprint, while TLV3603DCKR adds hysteresis/latch capability at the cost of an extra pin and no speed benefit-making TLV3601DCKT optimal for pure high-speed, space-constrained, single-function comparator use.

FAQ
What is the maximum operating temperature range for TLV3601DCKT?
The TLV3601DCKT is specified for operation from –40°C to +125°C ambient temperature. This range is validated per TI's Recommended Operating Conditions and applies to all electrical parameters in the datasheet, including propagation delay, input offset, and supply current. The TLV3603E variant extends to –55°C, but TLV3601DCKT does not support that extended range.
Does TLV3601DCKT support hysteresis or latch functionality?
No, TLV3601DCKT does not include hysteresis control or latch capability. Those features are exclusive to the TLV3603(E) family members, which add a dedicated LE/HYST pin. TLV3601DCKT operates in a single active mode with fixed internal hysteresis of 1.5–5 mV, as specified in its electrical characteristics table.
What package type is TLV3601DCKT supplied in, and is it RoHS-compliant?
TLV3601DCKT is supplied in a 5-pin SC70 (DCK) package with nominal dimensions 1.25 mm × 2.00 mm. It is RoHS-compliant, lead-free, and rated MSL-1 (moisture sensitivity level 1), meaning it can be stored indefinitely at ≤30°C/85% RH without baking prior to reflow.
Can TLV3601DCKT operate from a 2.5 V supply?
Yes, TLV3601DCKT is fully specified and characterized for operation from 2.4 V to 5.5 V. At 2.5 V supply, it delivers 2.5 ns typical propagation delay, 325 MHz toggle frequency, and maintains rail-to-rail input operation (VEE – 0.2 V to VCC + 0.2 V), making it suitable for low-voltage portable LIDAR and instrumentation designs.
Is functional safety documentation available for TLV3601DCKT?
Yes, Texas Instruments provides functional safety documentation for TLV3601DCKT, including FIT rate calculation, failure mode effects analysis (FMEA), and diagnostic coverage reports aligned with ISO 26262 ASIL-B and IEC 61508 SIL-2 requirements. These documents are accessible via TI's product folder and are intended to support system-level safety certification.
