Product details
Overview
TLV9034DR from Texas Instruments is a quad-channel, rail-to-rail input precision comparator with push-pull output, 1.65V–5.5V supply range, 300μV max input offset voltage, and 100ns typical propagation delay. It operates across –40°C to +125°C and supports fault-tolerant inputs up to 6V - ideal for voltage monitoring in motor drives and industrial control systems.
For engineers reviewing the TLV9034DR datasheet, TLV9034DR pinout, TLV9034DR application, or TLV9034DR equivalent, this page delivers verified package mapping (SOIC-14), confirmed push-pull output behavior, thermal performance data (RθJA = 136.0°C/W), and two validated alternative comparators for design flexibility.
Technical Context
The TLV9034DR implements a high-speed, low-power comparator architecture with internal biasing optimized for stable operation at 1.65V minimum supply. Its rail-to-rail input stage tolerates overvoltage up to 6V relative to V– without phase inversion or damage, enabling direct sensing in noisy power rails.
As a member of the TLV903x series, it features a push-pull output capable of sourcing/sinking ≥4mA per channel at 5V, supporting direct LED driving or MOSFET gate control without external pull-up resistors - distinguishing it from open-drain TLV902x variants.
Key Specifications

| Propagation Delay | 100ns (high-to-low, 5V, CL=15pF) - supports real-time response in overvoltage/undervoltage protection schemes. |
| Quiescent Current | 16μA per channel (typ) - allows four independent comparators to operate continuously in ultra-low-power industrial sensors. |
| Input Bias Current | 5pA (typ) - minimizes loading error on high-impedance voltage dividers used in battery monitoring. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and factory automation environments. |

Pinout & Package
TLV9034DR is packaged in a 14-pin SOIC (D) package measuring 3.91mm × 8.65mm, with exposed pad not present. Pin functions are defined per Table 4-3 of the datasheet for SOIC configuration.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Quad open-drain comparator; 2V–36V supply; 2mV offset; 300ns delay; no fault-tolerant inputs. | Requires external pull-ups; unsuitable for 1.65V operation or 6V overvoltage sensing. | Select when wide supply range and cost sensitivity outweigh speed, precision, and fault tolerance needs. |
| TLV9024DR | Quad open-drain variant in same family; identical supply, offset, and temperature specs but requires pull-up resistor. | Used where wired-OR logic or level translation to higher voltages is required. | Choose TLV9024DR only if open-drain functionality is explicitly needed - otherwise TLV9034DR reduces component count. |
Compared with LM339DR and TLV9024DR, the TLV9034DR delivers 3× faster response, 7× lower offset voltage, and integrated fault protection - making it optimal for next-generation industrial and appliance designs demanding compact, robust, low-power threshold detection.

FAQ
What is the maximum input voltage the TLV9034DR can tolerate without damage?
The TLV9034DR inputs tolerate –0.3V to +6V relative to V– across the full temperature range. This fault tolerance eliminates external clamping diodes when monitoring 24V or 48V rails, as confirmed in Section 5.1 Absolute Maximum Ratings and Section 3 Description of the datasheet. The TLV9034DR maintains correct output polarity even when inputs exceed V+.
Does the TLV9034DR support operation from a 1.8V supply?
Yes, the TLV9034DR is fully specified for 1.65V to 5.5V operation. Electrical Characteristics tables (Sections 5.7–5.11) confirm performance at 1.8V, including 16μA quiescent current per channel and ±0.3mV typical offset voltage. This makes the TLV9034DR suitable for battery-powered IoT sensors and low-voltage microcontroller interfaces.
Can the TLV9034DR outputs drive an LED directly?
Yes - the push-pull output of each TLV9034DR channel can source or sink ≥4mA at 5V (Section 5.7 OUTPUT specifications), sufficient to drive standard indicator LEDs without external transistors or pull-up resistors. This capability is unique to the TLV903x series and is not available in the open-drain TLV902x variants.
What is the thermal resistance (RθJA) of the TLV9034DR in SOIC-14 package?
The TLV9034DR in SOIC-14 (D) package has a junction-to-ambient thermal resistance (RθJA) of 136.0°C/W, as specified in Section 5.6 Thermal Information. This value assumes standard JEDEC 2-layer board conditions and enables reliable operation at full load up to +125°C ambient when mounted with adequate copper pour.
How does the TLV9034DR differ from the TLV9024DR?
The TLV9034DR features a push-pull output stage, while the TLV9024DR uses open-drain outputs. Both share identical supply range, offset voltage, propagation delay, and temperature rating. The TLV9034DR eliminates external pull-up resistors, reduces BOM count, and supports active-high signaling - whereas TLV9024DR enables wired-OR logic and level translation.
