Product details
Overview
TLV9034DYYR from Texas Instruments is a quad-channel precision comparator with push-pull output, rail-to-rail input (fault-tolerant to 6V), 300μV max input offset voltage, and 100ns typical propagation delay at 5V supply. It operates from 1.65V to 5.5V and supports industrial temperature range (–40°C to +125°C), enabling robust voltage monitoring in motor drive feedback loops and factory automation sensor interfaces.
For engineers reviewing the TLV9034DYYR datasheet, TLV9034DYYR pinout, TLV9034DYYR application, or TLV9034DYYR equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in harsh environments, and two confirmed alternative parts with documented functional and layout implications.
Technical Context
The TLV9034DYYR implements four independent high-speed comparators with internal biasing optimized for low quiescent current (16μA per channel) and precision DC performance. Its fault-tolerant inputs withstand overvoltage up to 6V beyond V– without phase inversion or damage, supporting direct connection to noisy industrial buses or unregulated sensor outputs.
Each channel features a push-pull output stage capable of sourcing/sinking ≥4mA, eliminating external pull-up resistors and enabling direct LED driving or MOSFET gate control. The device uses a single-supply architecture with common-mode input range extending 0.2V beyond both rails, simplifying level-shifting in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables operation from single Li-ion battery (3.0–3.7V) or 3.3V/5V logic rails without level translation. |
| Input Offset Voltage | ±0.3mV (typ), ±2mV (max, –40°C to +125°C) - Ensures accurate threshold detection in precision voltage monitors (e.g., battery undervoltage lockout). |
| Propagation Delay | 100ns (high-to-low), 115ns (low-to-high, push-pull) - Supports fast response in overcurrent protection circuits with <100ns reaction time. |
| Quiescent Current | 16μA per channel (typ) - Allows integration into always-on subsystems (e.g., HVAC standby monitoring) with sub-100μA total quiescent draw. |
| Input Common-Mode Range | (V–) – 0.2V to (V+) + 0.2V - Permits direct sensing of signals referenced to ground or V+ in single-supply configurations. |
| Output Drive Strength | ≥4mA sink/source capability - Drives LEDs directly or switches small-signal MOSFETs (e.g., N-channel load switches) without buffer stages. |
| ESD Rating | ±2kV HBM - Provides robustness against handling ESD in automated PCB assembly and field service environments. |
Pinout & Package
SOT-23-14 (DYY) package: 4.20mm × 2.00mm footprint with 0.65mm pitch, compatible with standard SMT reflow profiles and high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull output of comparator 1 - Active-high/low signal with rail-to-rail swing; no external pull-up required. |
| 2 | V+ | Positive supply input - Must be decoupled locally (0.1μF ceramic) to suppress switching noise coupling into analog inputs. |
| 3 | IN1– | Inverting input of comparator 1 - Accepts voltages from (V–) – 0.2V to (V+) + 0.2V; fault-tolerant to 6V. |
| 4 | IN1+ | Non-inverting input of comparator 1 - Same fault tolerance and common-mode range as IN1–. |
| 5 | IN2– | Inverting input of comparator 2 - Electrically identical to IN1–; enables dual-threshold detection on same signal path. |
| 6 | IN2+ | Non-inverting input of comparator 2 - Used with IN2– for window comparator configurations. |
| 7 | IN3– | Inverting input of comparator 3 - Supports third independent comparison channel (e.g., auxiliary supply monitoring). |
| 8 | IN3+ | Non-inverting input of comparator 3 - Paired with IN3– for dedicated overvoltage/undervoltage detection. |
| 9 | IN4– | Inverting input of comparator 4 - Enables fourth threshold check (e.g., thermal shutdown flag aggregation). |
| 10 | IN4+ | Non-inverting input of comparator 4 - Final input pair for multi-level system status evaluation. |
| 11 | GND | Negative supply reference - Must connect to low-impedance system ground plane; serves as return for all four outputs. |
| 12 | OUT4 | Push-pull output of comparator 4 - Independent output; can drive separate loads without crosstalk. |
| 13 | OUT3 | Push-pull output of comparator 3 - Dedicated output for third comparator's decision signal. |
| 14 | OUT2 | Push-pull output of comparator 2 - Provides second independent logic-level output for parallel processing. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Open-drain output, 2mV max offset, 300ns propagation delay, 1.5mA quiescent current per channel | Requires external pull-ups; unsuitable for direct LED/MOSFET drive; higher power limits use in battery-powered designs | Select LM339DR only when open-drain flexibility (wired-OR bus) is required and speed/power constraints allow. |
| TLV9034PW | Same electrical specs, TSSOP-14 package (4.40mm × 5.00mm), exposed thermal pad connected to GND | Larger footprint but better thermal dissipation for sustained 4mA output loading; requires GND pad soldering | Choose TLV9034PW for thermally demanding applications (e.g., continuous LED indicator arrays) where board area permits. |
Compared with LM339DR and TLV9034PW, TLV9034DYYR offers lowest quiescent current (16μA vs. 1.5mA) and fastest propagation (100ns vs. 300ns), making it optimal for space-constrained, low-power, high-speed industrial monitoring where SOT-23-14 fit is available.

FAQ
What is the maximum input voltage the TLV9034DYYR can tolerate without damage?
The TLV9034DYYR features fault-tolerant inputs rated for –0.3V to 6V relative to V–, meaning it withstands up to 6V applied to any IN+ or IN– pin regardless of supply voltage. This eliminates external clamping components in industrial sensor interfaces where transients exceed rail limits, and is validated across the full –40°C to +125°C temperature range per TI SNOSDA3H datasheet Section 5.1.
Does the TLV9034DYYR support rail-to-rail input common-mode range?
Yes, the TLV9034DYYR supports a common-mode input voltage range from (V–) – 0.2V to (V+) + 0.2V, enabling direct connection to signals referenced above or below the supply rails. This is confirmed in Section 5.3 (Recommended Operating Conditions) and Section 5.11 (Electrical Characteristics) of the TI datasheet, and applies to all four channels simultaneously.
Can the TLV9034DYYR drive a MOSFET gate directly?
Yes, the TLV9034DYYR's push-pull output can source and sink ≥4mA, sufficient to charge/discharge small-signal MOSFET gates (e.g., 2N7002, BSS138) within microseconds. Its 100ns propagation delay and rail-to-rail swing ensure fast, deterministic switching - verified in Section 5.11 Output specifications and Figure 5-7/5-11 of the TI datasheet.
What is the quiescent current per channel for TLV9034DYYR at 1.8V supply?
The TLV9034DYYR draws 16μA per channel (typical) at 1.8V supply with no load and output low, as specified in Section 5.11 (Electrical Characteristics) of the TI datasheet. This value holds across –40°C to +125°C, with maximum 35μA per channel under worst-case conditions, enabling ultra-low-power always-on monitoring.
Is the TLV9034DYYR pin-compatible with other packages in the TLV903x family?
No - the TLV9034DYYR (SOT-23-14) has a unique 14-pin linear pinout incompatible with SOIC-14 (D), TSSOP-14 (PW), or WQFN-16 (RTE) variants. Pin mapping differs significantly (e.g., GND is pin 11 in DYY but pin 12 in SOIC), so PCB layout must be tailored to the DYY package per Figure 4-5 and Table 4-3 in the TI datasheet.
