Product details
Overview
TLV7041DCKT from Texas Instruments is a single-channel, nanopower, open-drain comparator in SC-70-5 (DCK) package. It operates from 1.6V to 6.5V supply, draws only 315nA quiescent current, delivers 3µs propagation delay, and features rail-to-rail input with internal hysteresis - enabling precise voltage monitoring in battery-powered smoke detectors and portable gas sensors.
For engineers reviewing the TLV7041DCKT datasheet, TLV7041DCKT pinout, TLV7041DCKT application, or TLV7041DCKT equivalent, this page provides verified pin functions, real-world use cases in low-power sensing systems, confirmed electrical specs including input offset (±0.1mV typ), hysteresis (2–17mV), and validated alternatives for open-drain comparator selection.
Technical Context
The TLV7041DCKT implements a rail-to-rail input stage capable of accepting signals up to 100mV beyond VCC or below VEE, paired with an open-drain output stage that supports pull-up voltages exceeding VCC - making it suitable for level translation and bipolar-to-single-ended conversion. Its internal hysteresis (2–17mV) eliminates oscillation on slow-moving inputs in noisy environments.
A dedicated power-on-reset (POR) circuit holds the output in high-impedance state during power ramp-up until VCC ≥ 1.6V, ensuring glitch-free startup. The device maintains stable operation across –40°C to +125°C and exhibits ultra-low input bias current (2pA) and input offset current (1pA), critical for high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - compatible with 1.8V, 3.3V, and 5V systems; supports single-supply operation down to 1.6V minimum. |
| Quiescent Current | 315nA at 1.8V - enables multi-year battery life in always-on sensing nodes like smoke detectors. |
| Propagation Delay | 3µs at 5V, 100mV overdrive - fast enough to detect rapid fault transitions while preserving nanoPower efficiency. |
| Input Offset Voltage | ±0.1mV (min), ±8mV (max) - ensures accurate threshold detection in precision voltage monitoring applications. |
| Hysteresis | 2mV (min) to 17mV (max) - suppresses noise-induced chatter on slow analog inputs without external components. |
| Input Bias Current | 2pA - minimizes loading error when interfacing with high-impedance sources such as thermistors or electrochemical sensors. |
| Open-Drain Leakage | 100pA at 5V - guarantees reliable high-state retention in pull-up configurations used in I²C-compatible wake-up circuits. |
Pinout & Package
TLV7041DCKT is packaged in a 5-pin SC-70 (DCK) package measuring 2.00mm × 1.25mm, optimized for space-constrained PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Output | Open-drain output requiring external pull-up; supports voltage translation beyond VCC and wired-OR logic. |
| 2: IN− | Inverting Input | Differential input node; accepts rail-to-rail common-mode signals from VEE − 0.1V to VCC + 0.1V. |
| 3: IN+ | Non-Inverting Input | Differential input node; same rail-to-rail range as IN−; used for threshold comparison against reference or sensor signal. |
| 4: VEE | Negative Supply / Ground | Reference potential for single-supply operation; must be connected to system ground or lowest supply rail. |
| 5: VCC | Positive Supply | Main power input; supplies internal bias and POR circuit; minimum valid voltage is 1.6V (1.2V for S/L variants). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts input signals from VEE − 0.1V to VCC + 0.1V - enables direct interface with sensors operating near supply rails. |
| Internal hysteresis | 2–17mV programmable via supply and temperature - eliminates need for external positive feedback resistors in noisy environments. |
| Open-drain output | Supports pull-up to any voltage ≤7V - allows level shifting between 1.8V logic and 5V bus or interfacing with I²C-compatible interrupt lines. |
| No phase reversal | Maintains correct output polarity even when inputs exceed common-mode range - prevents false triggering during overvoltage transients. |
| Power-on-reset (POR) | Asserts high-impedance output until VCC ≥ 1.6V - eliminates startup glitches in battery-powered systems with slow-ramping supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7041DBVR | SOT-23-5 package (2.90mm × 1.60mm); identical electrical specs and pinout (North-West configuration). | Larger footprint but higher thermal mass; preferred for manual assembly or prototyping with breadboards. | Select TLV7041DBVR when board space permits and thermal dissipation under sustained load is a concern. |
| MAX9021AUT+T | 320nA quiescent current, 3.5µs propagation delay, 1.7V–5.5V supply; open-drain output; no internal hysteresis. | Requires external hysteresis resistor network; less suitable for noisy industrial environments without added components. | Choose MAX9021AUT+T only if legacy design compatibility or specific vendor qualification requirements mandate Maxim Integrated parts. |
Compared with TLV7041DBVR, TLV7041DCKT saves 55% board area in SC-70 packaging while maintaining identical functionality; versus MAX9021AUT+T, TLV7041DCKT eliminates external hysteresis components and extends supply range to 6.5V for wider system compatibility.

FAQ
What is the minimum supply voltage required for TLV7041DCKT to operate correctly?
The TLV7041DCKT requires a minimum supply voltage of 1.6V under standard operating conditions. However, the TLV7041DCKT variant with "S" pinout (which matches the SC-70 package) supports operation down to 1.2V - confirmed in Section 5.3 of the official datasheet. This extended range enables direct use with partially discharged lithium coin cells in long-life applications.
Does TLV7041DCKT include internal hysteresis, and how does it affect threshold stability?
Yes, TLV7041DCKT integrates internal hysteresis ranging from 2mV (minimum) to 17mV (maximum), depending on supply voltage and temperature. This built-in hysteresis prevents output oscillation when input signals cross the threshold slowly or in the presence of noise - eliminating the need for external feedback resistors and improving reliability in smoke detectors and gas sensors.
Can TLV7041DCKT drive an LED directly, or is external circuitry required?
TLV7041DCKT cannot drive an LED directly because it features an open-drain output - meaning it can only sink current, not source it. To drive an LED, connect the anode to a positive supply (e.g., VCC or higher) and the cathode to the OUT pin, with a series current-limiting resistor. This configuration leverages the device's ability to pull down and supports level-shifted signaling.
What is the purpose of the VEE pin on TLV7041DCKT, and how should it be connected?
The VEE pin on TLV7041DCKT serves as the negative supply or ground reference terminal. In single-supply applications - which constitute most use cases - VEE must be connected directly to system ground. It is not intended for negative voltage operation; applying voltage below ground risks violating absolute maximum ratings and may damage the device.
How does the power-on-reset (POR) function behave on TLV7041DCKT during startup?
During power-up, TLV7041DCKT's internal POR circuit holds the OUT pin in high-impedance (Hi-Z) state until VCC reaches and sustains ≥1.6V for at least 200µs. This prevents undefined or spurious output transitions during supply ramp-up - a critical feature for reliable wake-up signaling in battery-powered motion detectors and safety monitors.
