Product details
Overview
TLV3601DCKR 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 stage. It operates from 2.4 V to 5.5 V and is used in laser distance meters, LIDAR time-of-flight signal conditioning, and high-speed trigger circuits in oscilloscopes.
For engineers reviewing the TLV3601DCKR datasheet, TLV3601DCKR pinout, TLV3601DCKR application, or TLV3601DCKR equivalent, this page delivers verified electrical specs, SC70-5 package details, functional context for fast pulse detection, and validated alternative comparators for timing-critical designs.
Technical Context
The TLV3601DCKR implements a fully differential front-end with rail-to-rail input common-mode range (VEE – 0.2 V to VCC + 0.2 V) and a push-pull output stage eliminating external pull-up resistors. Its 2.5 ns propagation delay is specified at 50 mV overdrive and remains stable across 2.4–5.5 V supply and –40°C to +125°C ambient.
It supports narrow pulse detection down to 1.25 ns and exhibits low overdrive dispersion (600 ps), enabling accurate timing in high-frequency edge-detection applications such as clock/data recovery and LIDAR echo processing where jitter and skew directly impact resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5 ns typical at 50 mV overdrive - enables sub-nanosecond timing resolution in time-of-flight systems |
| Toggle frequency | 325 MHz - supports reliable decision-making on fast digital or RF-derived signals |
| Input offset voltage | ±5 mV max over –40°C to +125°C - ensures consistent threshold accuracy without calibration |
| Supply voltage range | 2.4 V to 5.5 V - interoperable with 2.5 V, 3.3 V, and 5 V logic domains and mixed-supply systems |
| Input common-mode range | VEE – 0.2 V to VCC + 0.2 V - accepts signals beyond rails, simplifying level-shifting in sensor interfaces |
| Output type | Push-pull - drives CMOS/TTL loads directly without external components, reducing board area and power |
| Minimum input pulse width | 1.25 ns - detects ultra-short events in laser ranging and high-speed data sampling |
Pinout & Package
TLV3601DCKR is packaged in a 5-pin SC70 (DCK) package with nominal body size 1.25 mm × 2.00 mm, optimized for space-constrained high-speed PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Push-pull output - sinks or sources current to drive downstream logic without pull-up resistor |
| 2 | VEE | Negative supply or ground reference - establishes lower rail for input and output swing |
| 3 | IN+ | Non-inverting input - accepts rail-to-rail analog signals up to 200 mV beyond VEE/VCC |
| 4 | IN− | Inverting input - differential pair input with 67 kΩ differential resistance and 5 MΩ common-mode impedance |
| 5 | VCC | Positive supply - powers internal amplifier and output stage; supports 2.4–5.5 V operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates 200 mV beyond both supply rails - eliminates need for external biasing in sensor front-ends |
| Low overdrive dispersion (600 ps) | Minimizes timing uncertainty across varying input amplitudes - critical for consistent pulse-width measurement |
| Known startup condition | Guaranteed defined output state after power-on - prevents metastability in synchronous trigger chains |
| Functional safety documentation support | TI provides FIT rate, failure mode, and diagnostic coverage data - accelerates ISO 26262/IEC 61508 system certification |
| ESD robustness | ±2000 V HBM - withstands handling and board-level ESD events without latch-up or parameter shift |
Applications
| Laser Distance Meter | High-Speed Oscilloscope Trigger |
|---|---|
Use Scenario: Measures time-of-flight of pulsed laser light reflected from targets to compute distance with <1 cm resolution. IC Role / Device Role / Timing Role: Compares photodiode amplifier output against threshold to generate precise start/stop timing edges for TDC. Use Value: 2.5 ns propagation delay and 1.25 ns minimum pulse width enable sub-nanosecond time resolution, directly improving distance accuracy. |
Use Scenario: Detects fast signal edges in real-time waveform acquisition to initiate digitization and display triggering. IC Role / Device Role / Timing Role: Acts as edge-sensitive comparator feeding FPGA or ASIC trigger logic with minimal latency. Use Value: 325 MHz toggle frequency and low overdrive dispersion ensure reliable triggering on GHz-range harmonics without false positives. |
| LIDAR Echo Detection | High-Speed Differential Line Receiver |
Use Scenario: Captures weak, short-duration return pulses from long-range LIDAR systems operating in noisy environments. IC Role / Device Role / Timing Role: Front-end comparator converting analog echo signal into clean digital timing mark for time-of-flight calculation. Use Value: Rail-to-rail input range accommodates variable baseline offsets; push-pull output drives FPGA I/O directly with no external components. |
Use Scenario: Receives high-speed serial data from differential transmission lines (e.g., LVDS-like signals) and converts to single-ended logic levels. IC Role / Device Role / Timing Role: Single-ended conversion stage with fast response, interfacing differential sensors or communication links to digital controllers. Use Value: 2.4–5.5 V supply range allows direct interface to 3.3 V or 5 V microcontrollers; low input capacitance (1 pF) minimizes signal integrity degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3601DBVR | Same core specs (2.5 ns tPD, 325 MHz, push-pull), but in 5-pin SOT-23-5 (2.90 mm × 1.60 mm) - larger footprint, higher thermal resistance (RθJA = 176.5°C/W vs. 187.5°C/W). | Suitable for less space-constrained boards where thermal margin is prioritized over miniaturization. | Select TLV3601DBVR only if SC70 assembly capability is unavailable or board layout requires larger pad spacing. |
| LMH7322MA/NOPB | Dual-channel, 4.5 ns tPD, 350 MHz toggle, differential outputs - lacks rail-to-rail inputs and push-pull drive; requires external termination and level-shifting. | Better suited for dual-signal monitoring or differential receiver architectures where channel density outweighs single-channel speed. | Choose LMH7322MA/NOPB when dual comparators are needed and system design accommodates differential signaling overhead. |
Compared with TLV3601DCKR, TLV3601DBVR offers identical performance in a larger, more manufacturable package, while LMH7322MA/NOPB trades single-channel speed for dual-channel capability and differential flexibility - neither is pin-compatible, and both require layout changes.

FAQ
What is the maximum operating temperature for TLV3601DCKR?
The TLV3601DCKR is rated for operation from –40°C to +125°C ambient temperature under recommended conditions. This extended range supports deployment in automotive cabin modules, industrial laser scanners, and outdoor LIDAR enclosures where thermal management is constrained. The TLV3603E variant extends to –55°C, but TLV3601DCKR does not.
Does TLV3601DCKR support rail-to-rail input operation?
Yes, TLV3601DCKR supports input common-mode voltages from VEE – 0.2 V to VCC + 0.2 V - meaning it accepts signals 200 mV below ground or above VCC. This eliminates the need for external bias networks when interfacing with sensors or AC-coupled sources, and is confirmed in Section 6.3 and Figure 6-5 through 6-10 of the datasheet.
Is TLV3601DCKR pin-compatible with TLV3603 or TLV3603E?
No, TLV3601DCKR is not pin-compatible with TLV3603 or TLV3603E. TLV3601DCKR uses a 5-pin SC70 package (IN+, IN−, OUT, VEE, VCC), while TLV3603(E) uses a 6-pin SC70 adding the LE/HYST control pin. Pin 5 on TLV3601DCKR is VCC; on TLV3603(E), pin 5 is LE/HYST and VCC moves to pin 6 - requiring PCB redesign.
What is the output drive capability of TLV3601DCKR?
TLV3601DCKR features a push-pull output capable of sourcing or sinking ≥1 mA while maintaining VOH ≤ 80 mV below VCC and VOL ≤ 80 mV above VEE. Short-circuit output current is rated at ±10 mA to ±30 mA, allowing direct interface to standard CMOS and TTL logic families without external buffering or pull-up resistors.
Can TLV3601DCKR be used in functional safety–certified systems?
Yes, TLV3601DCKR is functional safety capable: Texas Instruments provides documented FIT rate, failure mode analysis, and diagnostic coverage data per ISO 26262 and IEC 61508 requirements. This documentation is explicitly referenced in the "Functional Safety Capable" section of the datasheet for TLV3601/2, supporting its use in ASIL-B or SIL-2 subsystems.
