Product details
Overview
TLV7034RTER from Texas Instruments is a quad-channel, nanopower, rail-to-rail input comparator with push-pull output, operating from 1.6V to 6.5V supply, consuming only 315nA quiescent current per channel, featuring 3µs propagation delay and internal hysteresis-used for precision voltage monitoring in battery-powered smoke detectors and portable gas meters.
For engineers reviewing the TLV7034RTER datasheet, TLV7034RTER pinout, TLV7034RTER application, or TLV7034RTER equivalent, key selection considerations include per-channel supply current, push-pull drive capability, thermal performance in WQFN-16, and compatibility with 1.6V–6.5V single-supply systems requiring fast fault response without external hysteresis.
Technical Context
The TLV7034RTER implements a rail-to-rail input stage capable of accepting common-mode voltages up to 100mV beyond VCC, with internal hysteresis (3–25mV) eliminating need for external feedback. Its power-on-reset circuit holds outputs low during supply ramp-up until VCC ≥ 1.6V.
Each of the four independent comparators features matched input offset voltage (±0.1mV min, ±8mV max), ultra-low input bias current (2pA), and operates across –40°C to +125°C ambient temperature-enabling reliable threshold detection in noisy, thermally variable industrial sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables simultaneous monitoring of four independent analog thresholds in compact space-constrained designs |
| Supply Voltage Range | 1.6V to 6.5V - supports direct operation from single Li-ion, 3.3V, or 5V rails without level-shifting |
| Quiescent Current / Channel | 315nA - allows multi-year battery life in always-on gas or motion detectors |
| Propagation Delay | 3µs - provides rapid fault response while maintaining nanoPower efficiency |
| Input Offset Voltage | ±0.1mV (min), ±8mV (max) - ensures accurate trip-point stability across temperature and supply |
| Output Type | Push-pull - sinks/sours >3mA, enabling direct LED drive or capacitive load switching without pull-up resistor |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin modules and industrial metering environments |
Pinout & Package
TLV7034RTER is housed in a 16-pin WQFN package (3.0mm × 3.0mm, 0.5mm pitch) with exposed thermal pad connected to VEE. Pinout follows standard quad-comparator layout optimized for signal isolation and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Push-pull digital outputs - each drives high/low actively; no external pull-up required |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - accept rail-to-rail signals including below VEE and above VCC |
| 3, 5, 10, 12 | +IN A/B/C/D | Non-inverting inputs - matched offset and bias for precise differential sensing |
| 4 | VCC | Positive supply - powers all four comparators; decoupling capacitor required at pin |
| 11 | VEE | Negative supply or ground - reference for all inputs/outputs; connects to thermal pad |
| 3, 10 | NC | No internal connection - must be left floating or tied to VEE for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts common-mode voltages from VEE – 0.1V to VCC + 0.1V - eliminates input clamping diodes and enables direct battery-voltage monitoring |
| Internal hysteresis | 3–25mV typical - prevents output oscillation on slow-moving or noisy inputs without external components |
| Power-on-reset (POR) | Holds outputs low until VCC ≥ 1.6V - ensures known state during power ramp-up, critical for safety-critical sensing |
| Ultra-low input bias current | 2pA maximum - minimizes loading error on high-impedance sensor sources like thermistors or pH electrodes |
| High CMRR & PSRR | 73dB CMRR, 77dB PSRR - rejects noise from shared supply rails and common-mode interference in mixed-signal PCBs |
Applications
| Smoke & Heat Detector | Gas Meter |
|---|---|
Use Scenario: Detects voltage thresholds from thermistor or ionization chamber to trigger alarm when temperature or particle density exceeds safe limits. IC Role / Device Role / Timing Role: Quad comparator monitors multiple sensor inputs simultaneously-e.g., ambient temp, chamber voltage, battery health, and tamper switch. Use Value: 315nA/channel current extends 10-year battery life; 3µs response ensures timely fire alert without false triggers from EMI. | Use Scenario: Compares analog outputs from MEMS pressure sensors and electrochemical gas cells to detect hazardous concentration levels. IC Role / Device Role / Timing Role: Four independent channels implement over-range, under-range, calibration check, and low-battery flags in a single IC. Use Value: Rail-to-rail input accepts full sensor swing (0–3.3V); internal hysteresis eliminates need for discrete Schmitt triggers. |
| Motion Detector | Servo Drive Position Sensor |
Use Scenario: Processes PIR sensor output to distinguish true motion from thermal drift using dual-threshold window comparison. IC Role / Device Role / Timing Role: Two comparators form a hysteresis window; third validates supply; fourth monitors wake-up timer voltage. Use Value: 1.6V minimum supply enables operation directly from coin-cell; 125°C rating supports attic/wall-mount enclosures. | Use Scenario: Monitors feedback voltage from potentiometer or resolver in closed-loop servo position control. IC Role / Device Role / Timing Role: One channel detects end-stop limit; another verifies motor enable logic; remaining two validate encoder supply and reference. Use Value: Push-pull outputs drive optocoupler inputs directly; ±0.1mV offset ensures sub-degree angular accuracy in positioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7044RTER | Open-drain output instead of push-pull; identical supply range, current, and delay | Requires external pull-up for logic-high; suited for wired-OR bus or level translation | Select TLV7044RTER only if system requires open-drain behavior (e.g., I²C-compatible alert lines) |
| LM339DR | Higher supply current (500µA vs 315nA), wider supply range (2–36V), no internal hysteresis, SOIC-14 package | Not suitable for battery life >1 year; requires external hysteresis resistors and decoupling | Choose LM339DR only for legacy 36V industrial systems where ultra-low power is not required |
Compared with TLV7044RTER and LM339DR, TLV7034RTER delivers 1,500× lower supply current than LM339DR and enables direct drive of LEDs or logic gates without pull-ups-making it optimal for space- and energy-constrained portable safety devices.

FAQ
What is the maximum supply voltage for TLV7034RTER?
The absolute maximum supply voltage (VCC – VEE) for TLV7034RTER is 7V, but the recommended operating range is 1.6V to 6.5V. Exceeding 6.5V may cause permanent damage or parametric shift. Operation at 6.5V is fully characterized and supported across –40°C to +125°C, making TLV7034RTER compatible with both 3.3V and 5V systems without regulation.
Does TLV7034RTER require external hysteresis resistors?
No, TLV7034RTER includes internal hysteresis (3–25mV typical) designed to prevent output chatter on slow or noisy inputs. This eliminates the need for external positive-feedback resistors, reducing BOM count and PCB area-especially valuable in compact gas meter or wearable sensor designs where layout space is constrained.
Can TLV7034RTER operate from a 1.8V lithium coin cell?
Yes, TLV7034RTER is fully specified down to 1.6V supply and functions reliably at 1.8V. Its 315nA per-channel quiescent current enables multi-year operation from CR2032 cells in always-on applications like wireless smoke alarms-verified across –40°C to +85°C with no startup delay or output instability.
What is the purpose of the exposed thermal pad on TLV7034RTER?
TLV7034RTER's exposed thermal pad (pin 15) must be soldered to a VEE-connected copper pour to achieve RθJB = 40.5°C/W. This thermal path reduces junction temperature rise by >30°C versus no-pad connection, ensuring long-term reliability in sealed enclosures like smart thermostats or industrial flow meters where ambient temperatures exceed 85°C.
How does the power-on-reset (POR) function behave in TLV7034RTER?
During power-up, TLV7034RTER's POR circuit holds all four outputs low until VCC reaches and sustains ≥1.6V for 200µs. This guarantees a defined initial state-critical in safety systems where undefined comparator outputs could falsely trigger alarms or disable actuators before firmware initialization completes.
