Product details
Overview
TLV1702AIRUGR from Texas Instruments is a dual-channel, rail-to-rail input microPower comparator with open-collector outputs, 55 µA per channel quiescent current, 560 ns low-to-high propagation delay at 2.2 V supply, and operation across –40°C to +125°C for industrial overvoltage detection and window comparator applications.
For engineers reviewing the TLV1702AIRUGR datasheet, TLV1702AIRUGR pinout, TLV1702AIRUGR application, or TLV1702AIRUGR equivalent, this page delivers verified electrical parameters, X2QFN-8 package mapping, temperature-stable propagation delay behavior, and real-world design context for high-voltage sensing and hysteresis-based thresholding circuits.
Technical Context
The TLV1702AIRUGR implements a rail-to-rail input stage that accepts common-mode voltages from V– to V+, enabling precise detection near supply rails. Its open-collector output supports wired-OR configurations and pull-up to up to +36 V regardless of its own supply voltage.
It operates from a single 2.2 V to 36 V supply or dual ±1.1 V to ±18 V supplies, with input offset voltage drift of ±4 µV/°C and power-supply rejection ratio of 20 µV/V over full temperature range - critical for stable thresholding in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.2 V to +36 V (single) or ±1.1 V to ±18 V (dual) - enables direct interface with 3.3 V, 5 V, 12 V, 24 V, and 36 V systems without level-shifting. |
| Quiescent Current | 55 µA per channel - allows battery-powered or energy-harvested designs to operate for years on small coin cells. |
| Propagation Delay | 560 ns (low-to-high), 460 ns (high-to-low) at 100 mV overdrive - ensures fast response for transient fault detection in power supplies. |
| Input Offset Voltage | ±300 µV (typical), ±5.5 mV (max over –40°C to +125°C) - supports accurate voltage thresholds in precision monitoring circuits. |
| Input Common-Mode Range | V– to V+ - permits direct sensing of signals at ground or rail, eliminating need for external biasing networks. |
| Output Type | Open-collector - enables flexible logic-level translation, wired-OR combining, and pull-up to higher voltage than V+ (up to +36 V). |
| ESD Rating | ±2000 V HBM - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
X2QFN-8 (RUG) package: 1.50 mm × 1.50 mm, 0.5-mm pitch, thermally enhanced bottom-exposed pad, no lead, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-collector output for comparator channel 1 - requires external pull-up; sinks current when asserted. |
| 2 | IN1– | Inverting input for channel 1 - accepts rail-to-rail common-mode voltage; phase-inversion immune. |
| 3 | V+ | Positive supply pin - connects to highest potential in single- or dual-supply configuration. |
| 4 | IN1+ | Noninverting input for channel 1 - used with IN1– to define threshold; matched input impedance. |
| 5 | IN2+ | Noninverting input for channel 2 - independent of channel 1; enables dual-threshold or differential sensing. |
| 6 | IN2– | Inverting input for channel 2 - rail-to-rail capable; supports independent reference or feedback path. |
| 7 | OUT2 | Open-collector output for comparator channel 2 - electrically isolated from OUT1; supports parallel or cascaded logic. |
| 8 | V– | Negative supply pin - connects to lowest potential (GND in single-supply, –VS in dual-supply). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail inputs | Enables direct sensing of signals at V– or V+ without external resistive dividers or biasing - reduces BOM count and layout area. |
| 55 µA per channel quiescent current | Supports always-on system monitoring in battery-backed controllers and IoT edge nodes with multi-year runtime. |
| 560 ns propagation delay at 2.2 V | Delivers sub-microsecond response even at minimum supply - critical for fast overvoltage shutdown in DC-DC converters. |
| Open-collector outputs with 36 V tolerance | Allows output pull-up to higher voltage rails (e.g., 12 V or 24 V) while operating from 3.3 V - simplifies mixed-voltage interface design. |

|
Use Scenario: Monitoring current through shunt resistor in 36 V solar charge controller to detect overcurrent faults before MOSFET thermal runaway. IC Role / Device Role / Timing Role: One comparator compares amplified shunt voltage against fixed reference; open-collector output drives fault latch. Use Value: Input common-mode range includes V+ (36 V), allowing direct connection to high-side shunt without level-shifting op amp. |
Use Scenario: Synchronizing microcontroller ADC sampling to AC line zero-crossing in smart metering and lighting control. IC Role / Device Role / Timing Role: Single channel compares scaled AC waveform against ground-referenced threshold; output toggles at polarity reversal. Use Value: Low input bias current (5 nA typ.) prevents loading of high-impedance transformer or capacitive divider networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel open-collector comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1702IDGKR | VSSOP-8 package (3.0 mm × 3.0 mm); identical electrical specs and pinout; higher thermal resistance (199 °C/W vs 205.6 °C/W). | Better suited for manual assembly or prototyping due to larger pad spacing; less space-constrained than RUG. | Select TLV1702IDGKR when board real estate allows larger footprint and hand-soldering is required. |
| LM393DR | Higher quiescent current (500 µA vs 55 µA); slower propagation delay (1.3 µs typ.); wider offset voltage (±7 mV max); no rail-to-rail inputs. | Limited to low-speed, non-rail-sensing applications; unsuitable for battery-powered or precision thresholding. | Choose LM393DR only for cost-sensitive, non-critical 5 V systems where power and accuracy are secondary. |
Compared with TLV1702IDGKR, TLV1702AIRUGR saves 54% board area and improves thermal performance marginally; compared with LM393DR, it delivers 9x lower supply current, 2.3x faster response, and rail-to-rail input capability essential for modern wide-input-range systems.

FAQ
What is the maximum allowable supply voltage for TLV1702AIRUGR?
The absolute maximum supply voltage for TLV1702AIRUGR is +40 V (or ±20 V). Operation beyond this rating risks permanent damage. The recommended operating range is +2.2 V to +36 V (or ±1.1 V to ±18 V), and all published specifications - including propagation delay, offset voltage, and quiescent current - are guaranteed within this range. Always use 0.1-µF ceramic bypass capacitors at V+ and V– pins to ensure stability.
Does TLV1702AIRUGR support single-supply operation?
Yes, TLV1702AIRUGR fully supports single-supply operation from +2.2 V to +36 V. Its rail-to-rail input stage accepts common-mode voltages from V– (typically GND) to V+, and its open-collector outputs can be pulled up to any voltage ≤ +36 V above V– - enabling direct interface with 3.3 V, 5 V, or 24 V logic rails while powered from a single source. No dual-supply configuration is required.
What is the typical input offset voltage of TLV1702AIRUGR at room temperature?
The typical input offset voltage of TLV1702AIRUGR at TA = +25°C and VS = +2.2 V is ±300 µV. At VS = +36 V, it improves to ±200 µV (typical). Over the full operating temperature range (–40°C to +125°C), the maximum offset is ±5.5 mV. This low offset enables accurate threshold setting in precision voltage monitoring applications without trimming.
Can TLV1702AIRUGR drive an LED directly?
No, TLV1702AIRUGR cannot drive an LED directly because its open-collector output is a sink-only structure with no internal pull-up. To drive an LED, connect the anode to a positive supply (≤ +36 V) and the cathode to OUT1 or OUT2; the comparator will sink current when asserted. Ensure current-limiting resistor value limits sink current below 20 mA (absolute max short-circuit current) - e.g., 1 kΩ for ~3.3 mA at 3.3 V.
Is TLV1702AIRUGR pin-compatible with other packages in the TLV170x family?
No, TLV1702AIRUGR (X2QFN-8, RUG) is not pin-compatible with TLV1702IDGKR (VSSOP-8, DGK) or TLV1702IDBVR (SOT-23-8). While all share identical signal functionality and pin numbering logic, physical pin assignments differ: RUG places V+ on pin 3 and V– on pin 8, whereas DGK places V+ on pin 8 and V– on pin 4. PCB layout must match the specific package's pinout - no mechanical or electrical interchangeability exists between RUG and DGK.
