Product details
Overview
TLV3603DCKT from Texas Instruments is a 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 serves as a precision timing decision element in laser distance meters and LIDAR time-of-flight signal conditioning paths.
For engineers reviewing the TLV3603DCKT datasheet, TLV3603DCKT pinout, TLV3603DCKT application, or TLV3603DCKT equivalent, key selection criteria include adjustable hysteresis control via LE/HYS pin, latch functionality, narrow 1.25 ns pulse detection capability, and operation across –40°C to +125°C ambient temperature.
Technical Context
The TLV3603DCKT implements a single-channel, high-speed comparator architecture with internal push-pull output stage eliminating external pull-up resistors. Its input stage supports common-mode voltages from VEE – 0.2 V to VCC + 0.2 V and delivers 2.5 ns typical propagation delay at 50 mV overdrive.
It features dual-mode operation: active mode (LE/HYS pin pulled high or resistor-connected) enables adjustable hysteresis (0–60 mV), while latch mode (LE/HYS pin low) holds output state. Input bias current remains ≤5 µA across –40°C to +125°C, and quiescent current is 5.7–7.8 mA at VCC = 2.4–5.5 V.
Key Specifications

Pinout & Package
TLV3603DCKT is packaged in a 6-pin SC70 (DCK) package measuring 1.25 mm × 2.00 mm, optimized for space-constrained high-speed PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Output | Push-pull digital output capable of sourcing/sinking ≥1 mA; directly interfaces FPGA I/O, microcontroller GPIO, or logic analyzers without external termination |
| VEE | Negative power supply | Ground or negative rail reference; supports single-supply (0 V) or dual-supply (±2.5 V) configurations |
| IN+ | Non-inverting input | Differential input node with rail-to-rail common-mode range (VEE – 0.2 V to VCC + 0.2 V) |
| IN− | Inverting input | Differential input node matching IN+; enables precise threshold comparison with low input capacitance (1 pF) |
| LE/HYS | Latch enable / hysteresis control | Configures device mode: floating/resistor-grounded → adjustable hysteresis; logic-low → latch; logic-high → active compare |
| VCC | Positive power supply | Primary supply rail (2.4–5.5 V); powers internal amplifier and output stage; decoupling required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable hysteresis | Hysteresis voltage set from 0 mV to 60 mV via external resistor on LE/HYS pin - suppresses noise-induced false triggering in noisy sensor interfaces |
| Latch function | LE/HYS pin low holds output state indefinitely - enables edge capture and pulse stretching without external flip-flops |
| Rail-to-rail input range | Operates with inputs 200 mV beyond VEE and VCC - eliminates level-shifting circuitry when interfacing with sensors or DACs |
| Push-pull output | No external pull-up needed - reduces BOM count, board area, and power consumption vs. open-drain comparators |
| Low input offset drift | ±3.0 µV/°C - maintains threshold stability across wide temperature ranges without recalibration |
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 sub-millimeter resolution. IC Role / Device Role / Timing Role: Comparator detects leading edge of weak, fast-return photodiode signals; TLV3603DCKT's 1.25 ns pulse width capability captures short-duration echoes. Use Value: Enables <1 ns timing jitter and 2.5 ns propagation delay consistency across temperature, improving distance measurement repeatability. | Use Scenario: Generates precise trigger events from high-frequency analog waveforms in real-time oscilloscopes and logic analyzers. IC Role / Device Role / Timing Role: Acts as ultra-fast threshold detector on acquisition path; latched output provides stable trigger hold-off during waveform processing. Use Value: 325 MHz toggle frequency and 600 ps overdrive dispersion ensure reliable triggering on fast edges without amplitude-dependent timing skew. |
| LIDAR Distance Sensing | High-Speed Differential Line Receiver |
Use Scenario: Detects return pulses in automotive or drone-based LIDAR systems operating at multi-MHz pulse repetition rates. IC Role / Device Role / Timing Role: Front-end comparator in time-of-flight receiver chain; rail-to-rail inputs interface directly with transimpedance amplifier outputs. Use Value: Input common-mode range extending 200 mV beyond rails allows direct connection to biased photodiode amplifiers without AC coupling or level shifters. | Use Scenario: Converts high-speed differential signals (e.g., LVDS, PECL) to single-ended CMOS logic for FPGA or ASIC input. IC Role / Device Role / Timing Role: Single-ended comparator receiving one leg of differential pair; hysteresis suppresses common-mode noise on long traces. Use Value: Adjustable hysteresis (0–60 mV) via LE/HYS pin tailors noise immunity to specific line impedance and interference conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3603DCKR | Same electrical specs and pinout; tape-and-reel packaging (3,000 units) vs. DCKT's 250-unit reel | Identical functional use; suited for high-volume automated assembly | Select DCKR for production runs; DCKT for prototyping and validation |
| TLV3603EDCKR | Extended temperature range (–55°C to +125°C); otherwise identical pinout, speed, and hysteresis/latch functions | Required for aerospace, defense, or extended-temperature industrial deployments | Choose TLV3603EDCKR only when operation below –40°C is mandatory |
Compared with TLV3603DCKT, TLV3603DCKR offers identical performance in volume packaging, while TLV3603EDCKR adds extended cold-temperature capability-neither requires PCB layout changes, but thermal validation is needed for –55°C operation.

FAQ
What is the maximum operating temperature for TLV3603DCKT?
The TLV3603DCKT is rated 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 specifications including propagation delay, input offset, and hysteresis control. The TLV3603E variant extends the lower limit to –55°C, but TLV3603DCKT itself maintains full specification compliance across its stated range.
Does TLV3603DCKT require external pull-up resistors on its output?
No, TLV3603DCKT does not require external pull-up resistors. It features a true push-pull output stage capable of actively driving high and low states. This eliminates the need for external components, reduces power consumption versus open-drain alternatives, and ensures fast rise/fall times (0.75 ns each) without load-dependent delays.
How is hysteresis adjusted on TLV3603DCKT?
Hysteresis on TLV3603DCKT is adjusted by connecting an external resistor between the LE/HYS pin and ground. With RHYS = 150 kΩ, hysteresis is ~30 mV; with 56 kΩ, it increases to ~60 mV. Floating the LE/HYS pin yields ~3 mV hysteresis, while pulling it low disables hysteresis and activates latch mode. All configurations are supported across the full operating temperature range.
Can TLV3603DCKT operate with a single 2.5 V supply?
Yes, TLV3603DCKT operates fully specified with a single 2.5 V supply (VCC = 2.5 V, VEE = 0 V). Its rail-to-rail input stage accepts common-mode voltages from –0.2 V to +2.7 V, and the push-pull output swings from near 0 V to near 2.5 V. Propagation delay remains 2.5 ns typical, and quiescent current is 5.7–7.8 mA under these conditions.
What is the function of the LE/HYS pin on TLV3603DCKT?
The LE/HYS pin on TLV3603DCKT serves two distinct functions: when pulled high or terminated with a resistor to ground, it configures adjustable hysteresis for noise immunity; when driven logic-low, it places the device into latch mode, holding the output at its last valid state until the pin is returned high. No external clock or timing signal is required for latching.
