Product details
Overview
TLV7032DDFR from Texas Instruments is a dual-channel, nanopower, rail-to-rail input comparator with push-pull output, operating from 1.6V to 6.5V supply and consuming only 315nA quiescent current per channel. It delivers 3µs propagation delay, internal hysteresis, and –40°C to 125°C operation-enabling precise voltage monitoring in battery-powered gas detectors and motion sensors.
For engineers reviewing the TLV7032DDFR datasheet, TLV7032DDFR pinout, TLV7032DDFR application, or TLV7032DDFR equivalent, this page provides verified package mapping (8-pin WSON), confirmed dual-channel pin functions, real-world timing and offset performance, and validated alternatives for low-power analog sensing designs.
Technical Context
The TLV7032DDFR implements a rail-to-rail input stage capable of accepting common-mode voltages up to 100mV beyond VCC, with no phase reversal under overdriven inputs. Its internal hysteresis (3–25mV) ensures clean digital transitions in noisy environments.
It features a dedicated power-on-reset (POR) circuit that holds outputs low during power ramp-up until VCC ≥ 1.6V, and supports single-supply operation with VEE tied to ground. The push-pull output drives both high and low actively, sourcing/sinking up to 29mA/33mA at 5V.
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 without level-shifting |
| Quiescent Current / Channel | 315nA - enables multi-year battery life in always-on sensor nodes |
| Propagation Delay | 3µs - fast enough to detect transient fault conditions while maintaining nanoPower efficiency |
| Input Offset Voltage | ±0.1mV (min), ±8mV (max) - supports accurate threshold detection across temperature |
| Hysteresis | 3mV to 25mV - suppresses noise-induced chatter on slow-moving input signals |
| Common-Mode Range | Rail-to-rail +100mV beyond VCC - accommodates inputs exceeding supply rails in industrial sensing |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin, industrial control, and smart metering environments |
Pinout & Package
TLV7032DDFR is housed in an 8-pin WSON (DSG) package (2.00mm × 2.00mm) with exposed thermal pad connected to VEE for improved thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Push-pull active-high/active-low output; sinks/sours milliamps directly |
| INA– (Pin 2) | Inverting Input, Channel A | Differential input node; rail-to-rail capable, accepts signals down to VEE – 0.1V |
| INA+ (Pin 3) | Noninverting Input, Channel A | Differential input node; same rail-to-rail range as INA– |
| VCC (Pin 4) | Positive Supply | Main power input; POR activates below 1.6V; must exceed 1.6V for 200µs before valid output |
| INB– (Pin 6) | Inverting Input, Channel B | Independent second comparator input; electrically isolated from Channel A |
| OUTB (Pin 7) | Output, Channel B | Independent push-pull output; fully decoupled timing and loading behavior from OUTA |
| VEE (Pin 8) | Negative Supply / Ground | Reference for all inputs and outputs; thermal pad must be soldered to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with 100mV overvoltage tolerance | Enables direct connection to sensors or DACs exceeding VCC, eliminating external clamping diodes |
| Internal hysteresis (3–25mV) | Prevents oscillation on noisy or slowly varying inputs without requiring external feedback resistors |
| Power-on-reset (POR) circuit | Guarantees known low-state output during power-up, preventing spurious actuation in safety-critical circuits |
| Push-pull output stage | Drives LEDs, logic gates, or capacitive loads directly-no external pull-up resistor required |
| Ultra-low 315nA/channel supply current | Reduces system-level power budget by >90% vs. standard comparators, critical for coin-cell applications |
Applications
| Gas Detector | Motion Detector |
|---|---|
Use Scenario: Detects toxic gas concentration via electrochemical sensor output crossing preset thresholds. IC Role / Device Role / Timing Role: Dual comparator monitors two independent sensor channels (e.g., CO and H₂S) with independent hysteresis and fast 3µs response. Use Value: Nanopower operation extends battery life to >5 years; rail-to-rail input handles sensor offsets near ground or VCC. | Use Scenario: Processes PIR sensor output to trigger lighting or alarm when motion crosses dual-voltage windows. IC Role / Device Role / Timing Role: One channel detects rising edge (motion onset), second detects falling edge (motion cessation) with synchronized timing. Use Value: Internal hysteresis eliminates false triggers from ambient IR noise; 315nA current enables always-on sensing in battery-powered fixtures. |
| Smart Smoke Detector | Portable Medical Sensor |
Use Scenario: Compares photoelectric and ionization chamber outputs against calibrated smoke density thresholds. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous analog window comparison for multi-sensor fusion and fault detection. Use Value: –40°C to 125°C rating ensures reliability in attic or garage installations; push-pull outputs drive buzzer and LED directly. | Use Scenario: Monitors ECG or pulse oximetry signal integrity by comparing amplitude and slew rate against programmable limits. IC Role / Device Role / Timing Role: One channel validates signal presence (amplitude), second validates dynamic response (slew rate) to reject motion artifacts. Use Value: 3µs propagation delay enables real-time artifact rejection; 1.6V minimum supply supports single-cell LiFePO₄ operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7042DDFR | Open-drain output instead of push-pull; identical supply range, current, delay, and hysteresis | Requires external pull-up for logic-high output; suitable for wired-OR bus or level translation | Select TLV7042DDFR when interfacing with mixed-voltage logic or implementing shared interrupt lines |
| LP311MX/NOPB | Higher 1.1mA supply current; 200ns delay; no internal hysteresis; SOIC-8 package | Lacks rail-to-rail input and nanopower efficiency; requires external hysteresis resistors | Choose LP311MX/NOPB only when speed >1MHz is mandatory and power budget allows >3000× higher current |
Compared with TLV7042DDFR, TLV7032DDFR eliminates external pull-ups and simplifies PCB layout; versus LP311MX/NOPB, it reduces quiescent current by 99.97% and integrates hysteresis-making it optimal for long-life, space-constrained, noise-immune sensing.

FAQ
What is the maximum supply voltage for TLV7032DDFR?
The absolute maximum supply voltage (VCC – VEE) for TLV7032DDFR is 7V, but the recommended operating range is 1.6V to 6.5V. Exceeding 6.5V may cause permanent damage or parametric shift, and operation above 7V violates absolute maximum ratings per TI SLVSE13J datasheet Section 5.1.
Does TLV7032DDFR require external hysteresis resistors?
No, TLV7032DDFR includes internal hysteresis (3–25mV typical) as a fixed feature. This eliminates the need for external positive-feedback resistors, reducing component count and board area-especially valuable in compact sensor modules where layout space is constrained.
Can TLV7032DDFR operate from a 1.8V single supply?
Yes, TLV7032DDFR operates reliably from 1.8V single supply (VEE = GND, VCC = 1.8V). Its rail-to-rail input stage accepts common-mode voltages from VEE – 0.1V to VCC + 0.1V, and its 315nA quiescent current per channel remains stable across this range per datasheet Sections 5.3 and 5.9.
What is the function of the thermal pad on TLV7032DDFR's WSON package?
The exposed thermal pad on TLV7032DDFR's DSG (WSON) package must be soldered directly to the PCB's VEE (ground) plane. Per datasheet Section 4.2 and Thermal Table 5.5, this connection lowers RθJB to 72.5°C/W and improves thermal stability-critical for sustained operation at 125°C ambient in enclosed enclosures.
Is TLV7032DDFR pin-compatible with TLV7032DBVR?
No, TLV7032DDFR (WSON-8) and TLV7032DBVR (SOT-23-8) share identical electrical functionality and pin numbering but differ in physical package, pad layout, and thermal characteristics. They are not mechanically interchangeable-PCB footprint and reflow profile must be redesigned for each package variant.
