Product details
Overview
TLV3602DGKT 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, and push-pull outputs. It operates from 2.4 V to 5.5 V and delivers ±5 mV input offset voltage and 1.25 ns minimum detectable pulse width-enabling precise timing in LIDAR distance sensing and clock/data recovery circuits.
For engineers reviewing the TLV3602DGKT datasheet, TLV3602DGKT pinout, TLV3602DGKT application, or TLV3602DGKT equivalent, this page provides verified functional specifications, dual-channel timing behavior, VSSOP-8 package details, thermal metrics (RθJA = 170.5°C/W), and validated alternatives for high-speed comparator selection in time-of-flight and oscilloscope trigger systems.
Technical Context
The TLV3602DGKT implements two independent high-speed comparators in a single VSSOP-8 package, each featuring identical 2.5 ns typical propagation delay and 325 MHz toggle frequency under 50 mV overdrive. Its rail-to-rail input stage supports common-mode voltages from VEE – 0.2 V to VCC + 0.2 V, and its push-pull output drives directly into CMOS/TTL logic without external pull-ups.
Channel-to-channel propagation delay skew is specified at 24 ps (max), enabling precise differential timing applications. The device lacks hysteresis control or latch functionality-features exclusive to the TLV3603(E) variant-making it optimized for synchronous dual-compare tasks like high-speed line receiver channel pairing or dual-edge clock recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5 ns typical (50 mV overdrive); enables sub-nanosecond timing resolution in time-of-flight measurements |
| Toggle frequency | 325 MHz maximum; supports high-data-rate signal discrimination in serial link receivers |
| Input offset voltage | ±5 mV max (–40°C to +125°C); ensures consistent threshold accuracy across industrial temperature range |
| Supply voltage range | 2.4 V to 5.5 V; compatible with 2.5 V, 3.3 V, and 5 V logic domains without level-shifting |
| Input common-mode range | VEE – 0.2 V to VCC + 0.2 V; allows direct interface with sensors operating beyond supply rails |
| Minimum pulse width | 1.25 ns; detects narrow laser pulses in LIDAR and fast transient triggers in oscilloscopes |
| Channel skew | 24 ps max; maintains tight timing alignment between dual channels for differential signal processing |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, exposed thermal pad connected to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+ | Non-inverting input, channel 1 | Accepts rail-to-rail analog signals up to 200 mV beyond supplies; primary reference for first comparator |
| IN1– | Inverting input, channel 1 | Differential pair input for channel 1; used with IN1+ to determine output state transition |
| IN2– | Inverting input, channel 2 | Independent second comparator input; enables parallel comparison of two signal paths |

| OUT2 | Output, channel 2 | Independent push-pull output; electrically isolated from OUT1 for noise-sensitive dual-channel use |
| V– | Negative supply or ground | Reference for both comparators and thermal pad connection point; must be low-impedance |
| V+ | Positive supply | Primary power rail (2.4–5.5 V); powers both comparator cores and output stages |
Key Features

Applications
| Laser Distance Meter | High-Speed Oscilloscope Trigger |
|---|---|
Use Scenario: Detects leading edge of reflected laser pulse to compute round-trip time in handheld rangefinders. IC Role / Device Role / Timing Role: Dual comparator performs synchronized start/stop timing using separate channels for transmit and receive paths. Use Value: 2.5 ns propagation delay and 1.25 ns pulse width capability enable ±1.5 cm distance resolution at 10 m range. |
Use Scenario: Triggers acquisition on fast transient events (e.g., glitches, edges) in digital storage oscilloscopes. IC Role / Device Role / Timing Role: One channel monitors signal threshold; second channel validates edge polarity or width before triggering. Use Value: 325 MHz toggle frequency and 24 ps channel skew ensure accurate multi-level trigger sequencing without timing jitter. |
| LIDAR Distance Sensing | High-Speed Differential Line Receiver |
Use Scenario: Measures time-of-flight between emitted and returned infrared pulses in automotive or drone LIDAR systems. IC Role / Device Role / Timing Role: Dual comparator captures precise rising/falling edges of amplified photodiode signals for time-stamping. Use Value: Rail-to-rail inputs accept wide dynamic range sensor outputs; 2.5 ns delay minimizes timing uncertainty in sub-meter ranging. |
Use Scenario: Converts high-frequency differential data streams (e.g., LVDS, PECL) into single-ended logic levels for FPGA/CPU interfaces. IC Role / Device Role / Timing Role: Each channel processes one leg of differential pair; outputs combined via logic to reconstruct data. Use Value: Push-pull outputs drive 5 pF probe loads directly; 325 MHz bandwidth supports >1 Gbps serial data recovery. |
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 | Single-channel, SOT-23-5, same 2.5 ns delay and 325 MHz toggle frequency; no dual-channel capability | Suitable for space-constrained single-threshold detection; cannot replace dual-channel timing alignment needs | Select when only one comparator is required and board area is critical; not a drop-in replacement for TLV3602DGKT |
| LMH7322MA/NOPB | Dual-channel, 4.5 ns propagation delay, 2.7 V to 12.6 V supply, differential LVDS outputs | Requires external termination and level translation; higher power (14 mA/channel) but wider voltage range | Choose for systems needing LVDS compatibility or >5.5 V operation; requires PCB redesign due to different pinout and output type |
Compared with TLV3601DBVR, TLV3602DGKT adds channel redundancy and skew-controlled timing; compared with LMH7322MA/NOPB, it offers lower latency, lower supply voltage, and simpler push-pull interfacing-but lacks differential output support.

FAQ
What is the maximum operating temperature for TLV3602DGKT?
The TLV3602DGKT is rated for operation from –40°C to +125°C ambient temperature, matching the extended industrial range required for automotive LIDAR and industrial test equipment. This specification is confirmed in Section 6.3 (Recommended Operating Conditions) of the official TI datasheet SNOSDB1E.
Does TLV3602DGKT support adjustable hysteresis or latch mode?
No, TLV3602DGKT does not include hysteresis control or latch functionality. Those features are exclusive to the TLV3603(E) variant (6-pin SC70), which has a dedicated LE/HYST pin. The TLV3602DGKT is a dual-channel comparator with fixed internal hysteresis of 1.5–5 mV, as specified in Table 6-5 of the datasheet.
What is the thermal resistance (RθJA) of TLV3602DGKT in VSSOP-8 package?
The junction-to-ambient thermal resistance (RθJA) for TLV3602DGKT in the DGK (VSSOP-8) package is 170.5°C/W, per Table 6.4 of the TI datasheet SNOSDB1E. This value assumes standard JEDEC 2-layer board conditions and guides heatsinking requirements for continuous high-speed operation.
Can TLV3602DGKT operate from a 2.5 V supply?
Yes, TLV3602DGKT supports 2.5 V single-supply operation (VCC = 2.5 V, VEE = 0 V), as confirmed in Section 6.3 (Recommended Operating Conditions). All key AC specs-including 2.5 ns propagation delay and 325 MHz toggle frequency-are characterized at 2.5 V, 3.3 V, and 5 V supplies.
Is TLV3602DGKT pin-compatible with other TLV360x variants?
No, TLV3602DGKT (VSSOP-8) is not pin-compatible with TLV3601 (SC70-5/SOT-23-5) or TLV3603(E) (SC70-6). Its 8-pin VSSOP layout allocates dedicated pins for two full comparator channels (IN1+, IN1–, IN2–, IN2+, OUT1, OUT2, V–, V+), differing fundamentally from the 5- and 6-pin variants' single-channel configurations.
