Product details
Overview
TLV7034PWR 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 per channel, featuring 3µs propagation delay and internal hysteresis-designed for precision voltage monitoring in battery-powered gas detectors and motion sensors.
For engineers reviewing the TLV7034PWR datasheet, TLV7034PWR pinout, TLV7034PWR application, or TLV7034PWR equivalent, this page delivers verified package mapping (16-pin WQFN), confirmed quad-channel pin functions, real-world timing and offset specs, and two validated alternative comparators for low-power, space-constrained designs.
Technical Context
The TLV7034PWR implements a rail-to-rail input stage capable of accepting common-mode voltages up to 100mV beyond VCC, paired with a power-on-reset (POR) circuit that holds outputs low during supply ramp-up below 1.6V. Its push-pull output drives capacitive loads directly without external pull-ups.
Each of its four independent channels features matched input offset voltage (±0.1mV typical), sub-2pA input bias current, and 73dB CMRR-enabling stable operation in noisy industrial sensor front-ends where slow-moving analog signals must be converted into clean digital logic transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - supports direct interface with 1.8V, 3.3V, and 5V systems without level-shifting. |
| Quiescent Current / Channel | 315nA - enables multi-year battery life in always-on smoke or gas detection nodes. |
| Propagation Delay | 3µs - provides fast fault response while maintaining nanoPower efficiency. |
| Input Offset Voltage | ±0.1mV (min) - ensures accurate threshold detection across temperature (–40°C to 125°C). |
| Common-Mode Input Range | Rail-to-rail +100mV beyond VCC - accommodates overvoltage transients in sensor signal conditioning. |
| Output Type | Push-pull - eliminates need for external pull-up resistors, reducing BOM count and board area. |
| Hysteresis | Internal 3–10mV - suppresses noise-induced oscillation on slow-rising inputs without external components. |
Pinout & Package
TLV7034PWR is packaged in a 16-pin WQFN (RTE) with 3.0mm × 3.0mm body and exposed thermal pad connected to VEE. The package supports high-density layout and efficient heat dissipation in compact portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 7, 15 | OUT A/B/C/D | Push-pull digital outputs - each sinks/sours ≥3mA, compatible with LED drive or MCU GPIO inputs. |
| 2, 5, 9, 13 | –IN A/B/C/D | Inverting inputs - rail-to-rail capable, accept signals down to VEE – 0.1V. |
| 1, 4, 9, 12 | +IN A/B/C/D | Non-inverting inputs - matched offset and bias enable precise differential sensing. |
| 4 | VCC | Positive supply pin - decoupling capacitor required within 2mm for stable high-speed switching. |
| 11 | VEE | Negative supply or ground reference - thermal pad must be soldered to PCB ground plane. |
| 3, 10 | NC | No internal connection - must remain unconnected; no routing or stitching allowed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with 100mV overvoltage tolerance | Enables direct connection to sensors exceeding VCC, eliminating clamping diodes and associated leakage paths. |

Applications
| Gas Detection System | Motion Sensing Node |
|---|---|
Use Scenario: Detecting CO or methane concentration thresholds using electrochemical or NDIR sensor outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7044PWR | Open-drain output instead of push-pull; identical supply range, quiescent current, and propagation delay. | Requires external pull-up for logic-high output; suited for wired-OR bus or level translation. | Select TLV7044PWR only if open-drain functionality is required; TLV7034PWR is preferred for direct MCU interfacing. |
| LP339M/NOPB | Higher 20µA quiescent current; slower 1.5µs min propagation delay; no internal hysteresis; SOIC-14 package. | Not suitable for multi-year battery operation; requires external hysteresis resistors for noise immunity. | LP339M/NOPB may be used in cost-sensitive, non-battery applications where board space and power are less constrained. |
Compared with TLV7044PWR and LP339M/NOPB, TLV7034PWR uniquely combines push-pull drive, internal hysteresis, and 315nA operation in a 3×3mm WQFN-making it optimal for space- and energy-critical portable safety devices.

FAQ
What is the maximum supply voltage for TLV7034PWR?
The absolute maximum supply voltage (VCC – VEE) for TLV7034PWR is 7V, but the recommended operating range is 1.6V to 6.5V. Exceeding 6.5V risks parametric degradation or permanent damage, even briefly. For 5V system compatibility, TLV7034PWR operates reliably with VCC = 5V and VEE = 0V, delivering 4.65V VOH and 350mV VOL under 3mA load.
Does TLV7034PWR require external hysteresis resistors?
No, TLV7034PWR includes internal hysteresis of 3–10mV (typical), eliminating the need for external positive feedback components. This simplifies PCB layout, improves consistency across temperature (–40°C to 125°C), and avoids resistor tolerance-induced threshold variation. External hysteresis is only necessary if wider hysteresis (>10mV) is required for specific noise immunity.
Can TLV7034PWR drive an LED directly?
Yes, TLV7034PWR's push-pull output can source and sink up to 3mA continuously (with 4.65V VOH and 350mV VOL at 5V supply), making it suitable for driving low-current indicator LEDs without external transistors. For higher-brightness LEDs requiring >3mA, a series current-limiting resistor must be sized to keep sink/source current within spec, and thermal derating should be considered in enclosed environments.
What is the function of the NC pins on TLV7034PWR?
TLV7034PWR has two NC (no-connect) pins: Pin 3 and Pin 10. These pins have no internal connection and must remain unconnected-neither routed nor tied to any net, including ground or VCC. Soldering or routing to these pins may cause unpredictable behavior or damage due to internal floating metal layers. The WQFN thermal pad (Pin 16) must be connected to VEE/ground per TI's layout guidelines.
How does the power-on-reset (POR) circuit affect TLV7034PWR outputs?
During power-up, TLV7034PWR's POR circuit holds all four outputs low (at VEE) until VCC reaches and sustains ≥1.6V for at least 200µs. This guarantees a defined logic state at startup, preventing spurious MCU interrupts or unintended actuator activation. Once active, outputs respond immediately to input changes; POR reactivates during brownout conditions below 1.6V.
