Product details
Overview
TLV9034RTER 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 precise voltage monitoring in motor drives and factory automation systems.
For engineers reviewing the TLV9034RTER datasheet, TLV9034RTER pinout, TLV9034RTER application, or TLV9034RTER equivalent, key selection criteria include its quad push-pull output drive capability (±4mA), ultra-low quiescent current (16μA per channel), fault-tolerant inputs, and compatibility with low-voltage logic and MOSFET gate driving in space-constrained industrial PCBs.
Technical Context
The TLV9034RTER implements a high-speed, low-power comparator architecture optimized for precision threshold detection in noisy environments. Its input stage features ESD-protected, fault-tolerant differential pairs capable of accepting common-mode voltages up to 6V beyond V–, while maintaining phase stability and no output inversion.
Each of the four independent comparators delivers push-pull output with 75mV VOL (at 4mA sink) and 75mV VOH (at 4mA source) at 25°C, supporting direct LED driving and capacitive load switching without external pull-ups. The device uses a single-supply design with full rail-to-rail input common-mode range (V– – 0.2V to V+ + 0.2V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables operation from single Li-ion cells up to 5V logic rails without level-shifting. |
| Input Offset Voltage (max) | ±0.3 mV - Ensures accurate threshold detection with ≤0.6mV total uncertainty across temperature. |
| Propagation Delay (typ) | 100 ns - Supports real-time response in overvoltage/undervoltage protection circuits with <100ns latency. |
| Quiescent Current (per channel) | 16 μA - Allows battery-powered or always-on monitoring in energy-sensitive applications like building sensors. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply | Primary power rail connection; must be decoupled locally with ≥100nF ceramic capacitor. |

Key Features
| Feature | Design Value |
|---|---|

| ESD robustness (2kV HBM) | Meets IEC 61000-4-2 Level 2 system-level ESD immunity - improves field reliability in handheld and factory-floor equipment. |
Applications
| Motor Overcurrent Protection | Industrial Sensor Threshold Detection |
|---|---|

IC Role / Device Role / Timing Role: Dedicated comparator per rail with adjustable reference; push-pull outputs directly assert interrupt lines to host processor. Use Value: 16μA/channel quiescent current enables continuous supervision without compromising standby power budget in Energy Star–certified devices. |
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, higher 1.5mV offset, 300μA/channel IQ, no fault-tolerance beyond rails | Requires external pull-ups; unsuitable for direct MOSFET gate drive or rail-to-rail input sensing above V+ | Choose LM339DR only when cost is primary constraint and system already includes pull-up infrastructure. |
| TLV9034IPWR | Same electrical specs but in 14-pin TSSOP (PW) package; no thermal pad; larger footprint (4.4mm × 5.0mm) | Lower thermal resistance not required in low-power ambient environments; easier hand-soldering | Choose TLV9034IPWR for prototyping or lower-volume production where thermal performance is secondary to assembly simplicity. |
Compared with LM339DR and TLV9034IPWR, the TLV9034RTER provides superior thermal management via its exposed pad, eliminates external components with push-pull outputs, and enables robust operation in harsh voltage environments - making it optimal for compact, high-reliability industrial control designs.

FAQ
What is the maximum input voltage the TLV9034RTER can tolerate relative to V–?
The TLV9034RTER supports input voltages from –0.3V to +6V relative to V– without damage or output phase inversion. This fault-tolerant feature allows direct interfacing with 5V logic, 24V field signals, or transient-prone sensor outputs without external clamping diodes - a key advantage over standard comparators in industrial applications.
Does the TLV9034RTER require external pull-up resistors on its outputs?
No. The TLV9034RTER features true push-pull outputs capable of both sourcing and sinking up to 4mA per channel. Unlike open-drain comparators such as the TLV9024, it does not require external pull-up resistors - simplifying circuit design, reducing BOM count, and enabling direct LED driving or microcontroller interrupt assertion.
What is the typical propagation delay of the TLV9034RTER and under what conditions is it measured?
The TLV9034RTER has a typical propagation delay of 100ns for high-to-low transitions, measured at VS = 5V, VCM = VS/2, CL = 15pF, and VID = –100mV. This value reflects real-world performance in fast-response protection circuits, such as overvoltage lockout or motor phase fault detection, where deterministic timing is essential.
Can the TLV9034RTER operate from a 1.8V supply?
Yes. The TLV9034RTER is fully specified from 1.65V to 5.5V supply voltage. At 1.8V, it maintains 16μA per channel quiescent current, ±0.3mV input offset, and functional push-pull output swing - making it suitable for ultra-low-voltage battery-powered sensors and portable industrial tools where supply headroom is limited.
How should the exposed thermal pad on the TLV9034RTER (RTE package) be connected?
The exposed thermal pad on the TLV9034RTER must be soldered directly to the V– (ground) net on the PCB. This connection is mandatory for achieving the specified thermal performance (RθJA = 134.1°C/W) and ensuring reliable operation at full load across the –40°C to +125°C temperature range. Thermal vias to inner ground planes are recommended for high-power-density layouts.
