Product details
Overview
TLV7011DCKT from Texas Instruments is a single-channel, micropower comparator with push-pull output, rail-to-rail input capability, 5 µA quiescent current, 260 ns propagation delay (tPHL), and operation from 1.6 V to 6.5 V supply. It delivers precision voltage monitoring in battery-powered IR receivers and portable threshold detection circuits.
For engineers reviewing the TLV7011DCKT datasheet, TLV7011DCKT pinout, TLV7011DCKT application, or TLV7011DCKT equivalent, this page provides verified package mapping (SC70-5), confirmed switching characteristics, real-world use-value tradeoffs between speed and power, and validated alternative comparators for low-voltage, space-constrained designs.
Technical Context
The TLV7011DCKT implements a rail-to-rail input stage tolerant up to VCC + 100 mV and VEE – 0.3 V, with internal hysteresis (1.2–14 mV) and no phase reversal under overdriven inputs. Its push-pull output sources/sinks ≥3 mA at 5 V, enabling direct LED drive or capacitive load switching without external pull-up.
It integrates a Power-on-Reset (POR) circuit that holds output low during supply ramp-up until VCC ≥ 1.6 V, ensuring deterministic startup behavior. Operating across –40°C to +125°C, it maintains stable offset voltage (±0.5 mV typ) and CMRR (78 dB) in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V logic domains without level shifting. |
| Quiescent Current | 5 µA - enables multi-year battery life in always-on sensor monitors and wake-up circuits. |
| Propagation Delay | 260 ns (tPHL, VOD = 100 mV) - fast enough for 1 MHz signal edge detection in portable power management. |
| Input Offset Voltage | ±0.5 mV (typ), ±8 mV (max) - ensures accurate threshold discrimination down to sub-millivolt levels. |
| Common-Mode Range | VEE to VCC + 0.1 V - allows input signals exceeding VCC (e.g., 5.5 V inputs on 3.3 V supply) without damage or inversion. |
| Output Type | Push-pull - eliminates need for external pull-up resistor; drives loads directly with VOH ≥ 4.7 V / VOL ≤ 220 mV @ 3 mA. |
| Hysteresis | 1.2–14 mV - suppresses chatter in slow-moving or noisy analog inputs like battery voltage ramps. |
Pinout & Package
TLV7011DCKT is packaged in a 5-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for high-density PCB layouts in handheld devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Push-pull digital output; sinks/source ≥3 mA; compatible with 1.8 V–5 V logic families. |
| 2 (VEE) | Negative Supply | Ground reference or negative rail; must be connected for proper biasing and POR function. |
| 3 (IN+) | Noninverting Input | Differential input node with rail-to-rail common-mode range; fault-tolerant to 5.5 V regardless of VCC. |
| 4 (IN−) | Inverting Input | Differential input node with identical rail-to-rail and fault-tolerance specs as IN+. |
| 5 (VCC) | Positive Supply | Main power input; POR activates below 1.6 V; supplies internal bias and output stage. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with overvoltage tolerance | Accepts inputs from VEE to VCC + 0.1 V; survives up to 5.5 V even when unpowered - simplifies front-end protection in mixed-voltage systems. |
| Internal hysteresis | 1.2–14 mV programmable via supply and temperature - eliminates need for external positive feedback resistors in threshold detectors. |
| Power-on-reset (POR) | Holds OUT low during VCC ramp-up until ≥1.6 V - prevents spurious outputs during power sequencing in embedded controllers. |
| Ultra-low quiescent current | 5 µA across –40°C to +125°C - enables continuous monitoring in energy-harvesting and coin-cell applications. |
| No phase inversion on overdrive | Maintains correct output polarity even when IN+ or IN− exceeds supply rails - critical for reliable zero-crossing detection. |
Applications
| IR Receiver Front End | Portable Battery Monitor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7021DCKT | Open-drain output, same 5 µA IQ and 260 ns tPHL, but requires external pull-up and supports rail-to-rail output beyond VCC. | Suitable for level translation where output must exceed VCC (e.g., 3.3 V comparator driving 5 V bus). | Select TLV7021DCKT only when open-drain functionality or output voltage flexibility is required; not drop-in compatible due to different output architecture. |
| LMV331M5X/NOPB | Higher IQ (110 µA), slower tPHL (250–500 ns), wider supply range (2.7–5.5 V), no internal hysteresis. | Better for cost-sensitive, non-battery applications where speed and ultra-low power are secondary. | Choose LMV331M5X/NOPB if board space allows SOT-23-5 and design tolerates higher current draw; verify external hysteresis is added if needed. |
Compared with TLV7011DCKT, TLV7021DCKT offers output voltage flexibility at the cost of added external components, while LMV331M5X/NOPB trades micropower efficiency for broader legacy compatibility and lower unit cost - both require schematic and layout review before substitution.

FAQ
What is the maximum input voltage the TLV7011DCKT can tolerate without damage?
The TLV7011DCKT inputs are fault-tolerant up to 5.5 V independent of VCC, meaning they withstand signals from 0 V to 5.5 V even when unpowered or operating at 1.8 V. This eliminates need for clamping diodes in mixed-voltage interfaces. The absolute maximum rating remains VEE – 0.3 V to 6 V per datasheet Section 6.1, but 5.5 V is the guaranteed safe operating limit for fault tolerance.
Does TLV7011DCKT require external hysteresis for stable threshold detection?
No - TLV7011DCKT includes internal hysteresis ranging from 1.2 mV to 14 mV depending on supply and temperature. This built-in hysteresis suppresses output chatter caused by noise on slow-moving inputs, eliminating the need for external positive feedback resistors in most battery monitor and window comparator designs.
Can TLV7011DCKT operate from a 1.8 V supply while interfacing with 3.3 V logic?
Yes - TLV7011DCKT operates from 1.6 V to 6.5 V and features rail-to-rail inputs that accept voltages up to VCC + 0.1 V. With 1.8 V supply, it safely compares 3.3 V signals (within its 5.5 V fault-tolerant limit) and its push-pull output swings from near VEE to near VCC, making level translation straightforward using a simple resistive divider on the input side.
What is the purpose of the Power-on-Reset (POR) circuit in TLV7011DCKT?
The POR circuit in TLV7011DCKT holds the output low (at VEE) during power-up until VCC reaches ≥1.6 V, preventing undefined or glitchy outputs during supply ramp-up. This ensures deterministic startup in microcontroller wake-up circuits and avoids false triggers in safety-critical monitoring applications - a key reliability feature absent in many generic comparators.
How does TLV7011DCKT's 260 ns propagation delay impact its use in 38 kHz IR receiver designs?
At 38 kHz, the signal period is ~26.3 µs; TLV7011DCKT's 260 ns propagation delay introduces <1% timing error per edge, preserving pulse width fidelity required for NEC or RC-5 protocol decoding. Combined with its 5 µA supply current and SC70 footprint, it enables compact, low-power IR front ends without compromising responsiveness.
