Product details
Overview
TLV9034QDYYRQ1 from Texas Instruments is a quad-channel precision comparator with push-pull output, 300μV input offset voltage, 100ns propagation delay, and rail-to-rail fault-tolerant inputs supporting 1.65V–5.5V supply. It operates across –40°C to +125°C and drives MOSFET gates or LEDs in motor drive feedback loops.
For engineers reviewing the TLV9034QDYYRQ1 datasheet, TLV9034QDYYRQ1 pinout, TLV9034QDYYRQ1 application, or TLV9034QDYYRQ1 equivalent, this page delivers verified electrical specs, package-validated pin functions, automotive-grade thermal performance, and real-world implementation context for voltage monitoring in noisy industrial environments.
Technical Context
The TLV9034QDYYRQ1 implements four independent high-speed comparators with push-pull outputs capable of sourcing/sinking ≥4mA per channel at 5V supply. Its fault-tolerant inputs withstand up to 6V beyond V– without damage or phase inversion-critical for sensing in unregulated or transient-prone power rails.
Each comparator features 5pA input bias current, 2pF differential input capacitance, and 75–95dB PSRR over 1.8V–5.5V supply range. The device uses internal clamping and snapback ESD protection (±2kV HBM) and is qualified for automotive AEC-Q100 Grade 1 (–40°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.65V to 5.5V - supports direct interface with 1.8V, 3.3V, and 5V logic and analog domains without level-shifting. |
| Input Offset Voltage | ±0.3mV (typ) - enables accurate threshold detection down to sub-millivolt levels in precision voltage monitors. |
| Propagation Delay | 100ns (high-to-low), 115ns (low-to-high) - ensures fast response for overvoltage/undervoltage protection in motor control and power sequencing. |
| Quiescent Current | 16μA per channel - allows battery-powered or always-on monitoring circuits to maintain ultra-low standby power. |
| Input Bias Current | 5pA - minimizes loading error on high-impedance sensor nodes like thermistor or photodiode interfaces. |
| Input Voltage Range | (V–) – 0.2V to (V+) + 0.2V - supports rail-to-rail common-mode operation and fault tolerance up to 6V beyond V–. |
| Output Drive | Sinks/sources ≥4mA - directly drives LED indicators or MOSFET gate capacitance without external buffers. |
Pinout & Package
TLV9034QDYYRQ1 is packaged in a 14-pin SOT-23 (DYY) footprint measuring 4.20mm × 2.00mm, optimized for space-constrained PCB layouts in automotive and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 (Pin 2) | Comparator 1 output | Push-pull driver capable of sourcing/sinking ≥4mA; no external pull-up required. |
| V+ (Pin 3) | Positive supply | Accepts 1.65V–5.5V; powers all four comparators and internal bias circuitry. |
| IN1– (Pin 4) | Inverting input, Comp1 | Fault-tolerant: withstands –0.3V to 6V relative to V–; low 5pA bias current preserves signal integrity. |
| IN1+ (Pin 5) | Non-inverting input, Comp1 | Same fault tolerance and bias spec as IN1–; used for reference-based threshold comparison. |
| IN2– (Pin 6) | Inverting input, Comp2 | Independent channel with identical specs; enables dual-sensor monitoring or window-comparator topology. |
| IN2+ (Pin 7) | Non-inverting input, Comp2 | Paired with IN2– for second independent comparison function. |
| IN3– (Pin 8) | Inverting input, Comp3 | Third channel input; supports multi-zone monitoring (e.g., phase A/B/C overcurrent detection). |
| IN3+ (Pin 9) | Non-inverting input, Comp3 | Enables simultaneous evaluation of three distinct voltage thresholds. |
| IN4– (Pin 10) | Inverting input, Comp4 | Fourth independent input; used for system health check (e.g., supply UVLO + OVLO + temp alert + fault latch). |
| IN4+ (Pin 11) | Non-inverting input, Comp4 | Completes quad-channel capability for comprehensive analog condition monitoring. |
| GND (Pin 12) | Negative supply | Reference node for all inputs and outputs; must be connected to system ground plane with low impedance. |
| OUT4 (Pin 13) | Comparator 4 output | Push-pull output matching OUT1–OUT3; supports active-low or active-high assertion without external components. |
| OUT3 (Pin 14) | Comparator 3 output | Identical drive strength and timing to other outputs; enables synchronized multi-output signaling. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9034DR | Same quad push-pull architecture, but SOIC-14 package (3.91mm × 8.65mm); higher RθJA (136°C/W vs. 211.1°C/W for DYY). | Preferred for prototyping or through-hole assembly; less suitable for space-constrained automotive modules. | Select TLV9034DR when board area is not constrained and hand-soldering or socketing is required. |
| LM339AVQPWRQ1 | Quad open-drain comparator; requires external pull-up; 1.5mV offset (vs. 0.3mV); slower 300ns propagation. | Used where wired-OR logic or level translation is needed; not suitable for direct MOSFET gate drive. | Choose LM339AVQPWRQ1 only if open-drain topology and lower precision are acceptable for cost-sensitive legacy designs. |
Compared with TLV9034DR and LM339AVQPWRQ1, TLV9034QDYYRQ1 delivers superior speed (100ns vs. 136–300ns), lower offset (0.3mV vs. 1.5mV), and integrated push-pull drive-reducing BOM count and PCB area in automotive and industrial edge nodes.

FAQ
What is the maximum input voltage tolerance for TLV9034QDYYRQ1?
The TLV9034QDYYRQ1 inputs tolerate voltages from –0.3V to 6V relative to V–, enabling direct connection to unregulated supplies or transient-prone nodes without external clamping. This fault tolerance is validated across the full –40°C to +125°C operating range and is intrinsic to the internal ESD structure-not dependent on external components. TLV9034QDYYRQ1 maintains correct output polarity even when inputs exceed V+ by up to 1V.
Does TLV9034QDYYRQ1 require external pull-up resistors on its outputs?
No, TLV9034QDYYRQ1 does not require external pull-up resistors because it features a true push-pull output stage capable of both sourcing and sinking current. Each output can drive ≥4mA high or low at 5V supply, making it suitable for direct interface with microcontroller GPIOs, LEDs, or MOSFET gates. This eliminates BOM cost and board space associated with pull-up resistors-unlike open-drain comparators such as TLV9024.
What is the typical quiescent current per channel for TLV9034QDYYRQ1 at 1.8V supply?
The typical quiescent current per channel for TLV9034QDYYRQ1 is 16μA at 1.8V supply and 25°C, rising to ≤35μA across the full –40°C to +125°C temperature range. This ultra-low power consumption enables always-on monitoring in battery-backed systems, with total device current below 64μA for all four channels-critical for energy harvesting and low-power IoT edge nodes.
Is TLV9034QDYYRQ1 qualified for automotive applications?
Yes, TLV9034QDYYRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C ambient), with full characterization including HTOL, TC, and ESD testing per JEDEC standards. It carries the "Q1" suffix explicitly denoting automotive qualification, and is manufactured in TI's IATF 16949-certified facilities. TLV9034QDYYRQ1 meets stringent requirements for functional safety-aware designs in body control modules and battery disconnect units.
How does the input offset voltage of TLV9034QDYYRQ1 compare to standard comparators?
TLV9034QDYYRQ1 has a typical input offset voltage of ±0.3mV (300μV), significantly lower than standard comparators like LM339 (±2mV) or TLV3701 (±1.25mV). This precision enables accurate detection of small voltage differentials-for example, distinguishing 10mV changes in shunt-based current sensing or detecting 50mV battery cell imbalances. The offset remains stable across temperature (±0.5μV/°C drift), ensuring consistent performance in thermal cycling environments.
