Product details
Overview
TLV3602DGKR from Texas Instruments is a dual-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 enables narrow-pulse detection (1.25 ns) in LIDAR time-of-flight systems and clock/data recovery circuits.
For engineers reviewing the TLV3602DGKR datasheet, TLV3602DGKR pinout, TLV3602DGKR application, or TLV3602DGKR equivalent, key selection criteria include channel count, propagation delay skew (24 ps), VSSOP-8 package compatibility, and functional safety documentation support for automotive and industrial safety-critical designs.
Technical Context
The TLV3602DGKR implements a dual independent comparator architecture with fully differential input stages capable of common-mode operation from VEE – 0.2 V to VCC + 0.2 V. Each channel features matched internal design to achieve 24 ps max channel-to-channel propagation delay skew under 50 MHz square-wave excitation.
Its push-pull output drives capacitive loads up to 100 pF while maintaining sub-3.5 ns typical propagation delay across 2.4–5.5 V supply range and –40°C to +125°C ambient temperature. Input overdrive dispersion is limited to 600 ps, ensuring consistent timing response across varying signal amplitudes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5 ns typical (50 mV overdrive); ensures precise timing alignment in high-speed sampling and trigger circuits |
| Toggle frequency | 325 MHz maximum; supports reliable decision-making at RF and data-rate boundaries |
| Input offset voltage | ±5 mV max (–40°C to +125°C); enables 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 and mixed-supply systems |
| Channel-to-channel skew | 24 ps max; critical for synchronized dual-input applications like differential line receivers |
| Input common-mode range | VEE – 0.2 V to VCC + 0.2 V; allows direct interfacing with signals exceeding supply rails |
| Output type | Push-pull; eliminates need for external pull-up resistors and reduces power vs. open-drain alternatives |
Pinout & Package
TLV3602DGKR is packaged in an 8-pin VSSOP (DGK) with 3.00 mm × 3.00 mm body size and exposed thermal pad connected to V–. Pin functions are validated per TI SNOSDB1E Rev E.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+ | Non-inverting input, channel 1 | Accepts analog input referenced to system ground or negative rail; rail-to-rail capable |
| IN1– | Inverting input, channel 1 | Differential pair input with matched layout to IN1+ for low offset and skew |
| IN2– | Inverting input, channel 2 | Independent second channel input; electrically isolated from channel 1 |
| IN2+ | Non-inverting input, channel 2 | Second full-differential input path; supports dual-signal monitoring or redundancy |
| OUT1 | Output, channel 1 | Push-pull CMOS-compatible output; sinks or sources up to 30 mA |
| OUT2 | Output, channel 2 | Independent digital output; no cross-talk with OUT1 under specified load conditions |
| V– | Negative supply or ground | Primary return path; thermal pad must be soldered to PCB ground plane for thermal management |
| V+ | Positive supply | Single positive rail input (2.4–5.5 V); no separate VEE required when V– = GND |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates 200 mV beyond both supply rails-enables direct sensing of signals outside supply domain without level-shifting |
| 24 ps channel skew | Guaranteed matching between dual channels supports time-critical differential measurements and synchronous triggering |
| 1.25 ns minimum pulse width detection | Supports ultra-short event capture in laser pulse timing and time-of-flight distance measurement |
| Functional safety documentation | TI provides FIT rate, failure mode analysis, and diagnostic coverage reports for ISO 26262 ASIL-B compliance |
| Low overdrive dispersion (600 ps) | Minimizes timing jitter across input amplitude variations-critical for consistent edge detection in noisy environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3602DR | Same dual-channel architecture and electrical specs; packaged in SOIC-8 (D) instead of VSSOP-8 (DGK) | SOIC-8 offers easier manual soldering and prototyping but occupies ~2.5× more PCB area than VSSOP | Select TLV3602DR for breadboarding, legacy board reuse, or where thermal performance is less critical than footprint |
| LMH7322MA | Higher 4.5 ns propagation delay, 2.7 V to 12.6 V supply, and differential LVDS outputs-not pin-compatible | Designed for high-voltage, high-noise industrial interfaces; requires external termination and level translation | Choose LMH7322MA only when system requires LVDS signaling or extended supply range beyond 5.5 V |
Compared with TLV3602DR and LMH7322MA, TLV3602DGKR delivers optimal trade-off of speed, compact VSSOP-8 packaging, rail-to-rail input flexibility, and functional safety documentation-making it preferred for space-constrained, high-reliability LIDAR and CDR designs.

FAQ
What is the maximum operating temperature for TLV3602DGKR?
The TLV3602DGKR is rated for operation from –40°C to +125°C ambient temperature, as confirmed in Section 6.3 of the TI SNOSDB1E datasheet. This extended temperature range supports deployment in automotive engine compartments, industrial motor drives, and outdoor LIDAR enclosures without derating.
Does TLV3602DGKR support single-supply operation?
Yes, TLV3602DGKR supports true single-supply operation with V– connected to ground and V+ supplied from 2.4 V to 5.5 V. Its rail-to-rail inputs function down to V– – 0.2 V and up to V+ + 0.2 V, enabling direct interface with ground-referenced sensors and amplifiers without level-shifting circuitry.
Is TLV3602DGKR pin-compatible with other TLV360x variants?
No-TLV3602DGKR (VSSOP-8) is not pin-compatible with TLV3601 (SC70-5/SOT23-5) or TLV3603(E) (SC70-6). Its 8-pin dual-channel layout differs fundamentally from the 5- and 6-pin single-channel packages. Board redesign is required when substituting across family members.
What is the purpose of the thermal pad on TLV3602DGKR?
The exposed thermal pad on the TLV3602DGKR VSSOP package must be soldered directly to the V– (ground) plane on the PCB. Per Section 6.4 of the datasheet, this connection reduces junction-to-board thermal resistance to 92.4°C/W, preventing thermal shutdown during sustained 325 MHz toggling and ensuring long-term reliability.
Does TLV3602DGKR include hysteresis or latch functionality?
No-TLV3602DGKR is a dual-channel comparator without adjustable hysteresis or latch control. Those features are exclusive to the TLV3603(E) variant (6-pin SC70), which includes the LE/HYST pin. TLV3602DGKR provides fixed internal hysteresis of 1.5–5 mV, optimized for general-purpose high-speed comparison.
