Product details
Overview
TLV7034QPWRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 automotive-compliant rail-to-rail input comparator with push-pull output, 315 nA quiescent current per channel, 3 µs propagation delay, and internal 6.5 mV hysteresis - used for precision voltage monitoring in instrument clusters and telematics eCall systems.
For engineers reviewing the TLV7034QPWRQ1 datasheet, TLV7034QPWRQ1 pinout, TLV7034QPWRQ1 application, or TLV7034QPWRQ1 equivalent, this page delivers verified electrical specs, TSSOP-14 package details, functional safety documentation support, and validated alternatives for automotive-grade comparator selection.
Technical Context
The TLV7034QPWRQ1 implements a nanopower, rail-to-rail input stage capable of accepting common-mode voltages up to 100 mV beyond VCC (VEE to VCC + 0.1 V), with no phase reversal on overdriven inputs. Its internal power-on-reset circuit holds outputs low during supply ramp-up until VCC ≥ 1.6 V for ≥200 µs.
Each of its four independent comparators features 2 pA input bias current, ±0.1 mV typical input offset voltage, and 73 dB CMRR at 5 V supply - enabling stable operation in noisy automotive environments where slow-moving analog signals must be converted into clean digital logic levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - supports 1.8 V, 3.3 V, and 5 V automotive subsystems without level-shifting. |
| Quiescent Current / Channel | 315 nA - enables always-on fault monitoring in battery-powered modules like OBC and eCall. |
| Propagation Delay | 3 µs - provides fast response to overvoltage/undervoltage events while maintaining nanowatt efficiency. |
| Input Offset Voltage | ±0.1 mV (typ) - ensures high-accuracy threshold detection across –40°C to 125°C ambient range. |
| Internal Hysteresis | 6.5 mV - suppresses noise-induced chatter on slow-rising/falling signals in harsh EMI environments. |
| Output Type | Push-pull - drives logic inputs directly without external pull-up; sinks/sours ≥3 mA at 5 V. |
| Common-Mode Range | VEE to VCC + 0.1 V - allows direct sensing of battery rails and sensor outputs exceeding supply voltage. |
Pinout & Package
TSSOP-14 package (4.40 mm × 5.00 mm), lead-free, RoHS-compliant, qualified per AEC-Q100 Grade 1 (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Push-pull outputs - each can drive CMOS/TTL loads directly; no external pull-up required. |
| 2, 6, 9, 13 | IN– A/B/C/D | Inverting inputs - accept rail-to-rail common-mode signals up to VCC + 0.1 V. |
| 3, 5, 10, 12 | IN+ A/B/C/D | Noninverting inputs - identical voltage range and fault-tolerant behavior as IN– pins. |
| 4 | VCC | Positive supply - powers all four comparators; POR activates if < 1.6 V. |
| 11 | VEE | Negative supply or ground - defines lower common-mode limit and output low level. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates with inputs from VEE to VCC + 0.1 V - eliminates need for external attenuators when monitoring battery or sensor rails. |
| Internal hysteresis | 6.5 mV fixed - prevents oscillation on noisy or slowly varying signals without external resistor networks. |
| Power-on-reset (POR) | Holds all outputs low until VCC ≥ 1.6 V for ≥200 µs - ensures known startup state in automotive power sequencing. |
| No phase reversal | Maintains correct output polarity even when inputs exceed VCC or fall below VEE - critical for fault-sensing reliability. |
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation - meets thermal requirements for under-hood and dashboard applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7034PWR | Non-automotive grade; lacks AEC-Q100 qualification and extended temperature testing. | Not suitable for production automotive ECUs; limited to industrial or consumer prototypes. | Select only for pre-validation bench testing where automotive qualification is not required. |
| LM339QDRQ1 | Higher 1.1 mA/channel quiescent current; no internal hysteresis; open-drain output only. | Requires external hysteresis resistors and pull-ups; less suitable for ultra-low-power always-on monitoring. | Prefer when legacy design reuse or higher drive strength (>16 mA) is needed over nanopower operation. |
Compared with TLV7034QPWRQ1, TLV7034PWR omits automotive qualification and thermal validation, while LM339QDRQ1 trades 3.5× higher current draw and external component dependency for broader voltage tolerance and proven field reliability in non-battery-critical systems.

FAQ
What is the operating temperature range for TLV7034QPWRQ1?
The TLV7034QPWRQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. This rating applies across all electrical specifications in the datasheet and is validated through accelerated stress testing including HTOL, TC, and uHAST. The device maintains 315 nA quiescent current and 3 µs propagation delay across this full range.
Does TLV7034QPWRQ1 include internal hysteresis, and what is its value?
Yes, TLV7034QPWRQ1 includes fixed internal hysteresis of 6.5 mV (typical at 25°C). This value is specified in the Electrical Characteristics table for quad devices and remains stable across –40°C to +125°C. It eliminates the need for external positive feedback resistors in noise-prone automotive environments such as engine bay sensors or CAN bus power monitors.
What output configuration does TLV7034QPWRQ1 use, and how does it differ from TLV7044QPWRQ1?
TLV7034QPWRQ1 uses a push-pull output stage capable of both sourcing and sinking ≥3 mA per channel at 5 V supply. In contrast, TLV7044QPWRQ1 uses an open-drain output requiring an external pull-up resistor. This makes TLV7034QPWRQ1 ideal for direct CMOS/TTL interfacing in instrument clusters, while TLV7044QPWRQ1 suits wired-OR bus configurations or level translation.
Is TLV7034QPWRQ1 compatible with 1.8 V logic systems?
Yes, TLV7034QPWRQ1 operates down to 1.6 V supply and supports rail-to-rail inputs extending to VCC + 0.1 V. At 1.8 V supply, it delivers 3 µs propagation delay and maintains 6.5 mV hysteresis - enabling direct interface with 1.8 V microcontrollers and ADC reference monitors in modern automotive domain controllers without level shifters.
How does the power-on-reset (POR) function behave in TLV7034QPWRQ1?
In TLV7034QPWRQ1, the internal POR circuit holds all four outputs low (at VEE) whenever VCC is below 1.6 V. Once VCC reaches and sustains ≥1.6 V for ≥200 µs, the comparators become active and outputs reflect input states. This behavior ensures deterministic startup in automotive power domains where battery voltage ramps slowly after ignition.
