Product details
Overview
TLV3603DCKR-ET 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 rails, ±5 mV input offset voltage, and push-pull output. It operates from 2.4 V to 5.5 V and supports adjustable hysteresis and latch functionality via the LE/HYS pin-enabling precise timing capture in laser distance meters and LIDAR front-ends.
For engineers reviewing the TLV3603DCKR-ET datasheet, TLV3603DCKR-ET pinout, TLV3603DCKR-ET application, or TLV3603DCKR-ET equivalent, this device delivers verified sub-3 ns timing resolution, configurable noise immunity, and latch hold capability critical for time-of-flight signal conditioning, high-speed trigger circuits, and differential line receiver designs requiring deterministic edge detection.
Technical Context
The TLV3603DCKR-ET implements a single-channel, rail-to-rail input comparator core with a push-pull output stage eliminating external pull-up resistors. Its internal architecture supports two functional modes: active comparison (when LE/HYS is pulled high or resistor-biased) and transparent latch (when LE/HYS is driven low), with tSETUP = –1.4 ns and tHOLD = 7.2 ns.
It achieves 1.25 ns minimum detectable pulse width and 325 MHz toggle frequency under 50 mV overdrive, with overdrive dispersion limited to 600 ps. Input common-mode range spans VEE – 0.2 V to VCC + 0.2 V, and quiescent current is 5.7–7.8 mA across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5 ns typical at 50 mV overdrive - enables sub-nanosecond timing alignment in time-of-flight systems |
| Toggle frequency | 325 MHz - supports high-data-rate clock/data recovery without duty-cycle distortion |
| Input offset voltage | ±5 mV max - ensures accurate threshold crossing with minimal calibration overhead |
| Supply voltage range | 2.4 V to 5.5 V - interoperable 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 - accommodates signals beyond supply rails for robust signal acquisition |
| Minimum pulse width | 1.25 ns - detects narrow laser return pulses in LIDAR and rangefinder applications |
| Overdrive dispersion | 600 ps - maintains consistent timing across varying input amplitudes |
Pinout & Package
TLV3603DCKR-ET 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 | Push-pull output | Drives CMOS/TTL loads directly without pull-up; sinks/sourcing up to 30 mA |
| VEE | Negative power supply | Ground reference or negative rail; supports single-supply operation down to 0 V |
| IN+ | Non-inverting input | Rail-to-rail capable; accepts signals 200 mV below VEE or above VCC |
| IN− | Inverting input | Matched to IN+ for precision differential sensing; 1 pF input capacitance minimizes loading |
| LE/HYS | Latch enable / hysteresis control | Configures latch mode (low) or adjustable hysteresis (resistor to ground); VIH = VEE + 1.5 V |
| VCC | Positive power supply | Accepts 2.4–5.5 V; powers internal biasing and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable hysteresis control | Hysteresis voltage set from 0 mV to 60 mV via external resistor on LE/HYS pin - suppresses noise-induced false triggering |
| Transparent latch function | Output holds last state when LE/HYS is low; resumes comparison within nanoseconds after high transition - ideal for strobed sampling |
| Rail-to-rail input stage | Operates 200 mV beyond VEE and VCC - eliminates level-shifting in wide-dynamic-range sensor interfaces |
| Known startup condition | Guaranteed defined output state at power-on - prevents metastability in safety-critical trigger paths |
| Functional safety documentation | TI-provided FIT rate, failure mode analysis, and diagnostic coverage data - supports ISO 26262 ASIL-B system design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3603DCKT | Same electrical specs and pinout; tape-and-reel packaging differs (250 vs. 3000 units/reel) | No functional difference; suited for prototyping or low-volume production | Select TLV3603DCKT for evaluation or small-batch builds where reel size impacts inventory handling |
| TLV3603EDCKR | Extended temperature grade (–55°C to +125°C); identical pinout, hysteresis/latch features, and AC performance | Required for aerospace, defense, or industrial systems operating outside commercial temperature range | Choose TLV3603EDCKR when ambient operating temperature exceeds –40°C or falls below +125°C |

FAQ
What is the maximum operating temperature for TLV3603DCKR-ET?
The TLV3603DCKR-ET is rated for operation from –40°C to +125°C. This commercial-extended temperature range is validated per TI's recommended operating conditions and thermal characterization data, ensuring reliable performance in industrial and automotive under-hood environments where ambient heat buildup occurs.
Does TLV3603DCKR-ET support latch mode, and how is it enabled?
Yes, TLV3603DCKR-ET supports transparent latch mode. It is enabled by driving the LE/HYS pin low. When asserted, the output holds its last valid state regardless of input transitions. The device returns to active comparison mode within nanoseconds after LE/HYS is pulled high, with tSETUP = –1.4 ns and tHOLD = 7.2 ns specified.
Can TLV3603DCKR-ET operate from a single 3.3 V supply?
Yes, TLV3603DCKR-ET fully supports single-supply operation at 3.3 V. Its 2.4 V to 5.5 V supply range, rail-to-rail inputs (extending 200 mV beyond rails), and push-pull output allow direct interfacing with 3.3 V logic without level shifters or external bias networks - confirmed in TI's Electrical Characteristics table at VCC = 3.3 V, VEE = 0 V.
What is the input hysteresis range achievable with TLV3603DCKR-ET?
TLV3603DCKR-ET provides programmable hysteresis from 0 mV (LE/HYS = logic high) to 60 mV (LE/HYS = 56 kΩ to ground), with intermediate values such as 3 mV (floating) and 30 mV (150 kΩ). This is measured and characterized across temperature and supply voltage in TI's Figure 6-19 through 6-21.
Is TLV3603DCKR-ET pin-compatible with other devices in the TLV360x family?
No - TLV3603DCKR-ET uses a 6-pin SC70 (DCK) package with LE/HYS functionality, whereas TLV3601 uses a 5-pin SC70/SOT-23 and lacks the latch/hysteresis pin. TLV3602 is an 8-pin dual-channel device. Pin compatibility exists only within the TLV3603(E) variant group (e.g., TLV3603DCKR-ET, TLV3603DCKT, TLV3603EDCKR).
