Product details
Overview
TLV9032DDFR from Texas Instruments is a dual-channel, precision rail-to-rail input comparator with push-pull output, 300 µV max input offset voltage, 100 ns typical propagation delay, and 16 µA per-channel quiescent current across 1.65 V to 5.5 V supply. It operates from –40°C to +125°C and features fault-tolerant inputs (–0.3 V to 6 V) for robust voltage monitoring in motor drives and industrial control systems.
For engineers reviewing the TLV9032DDFR datasheet, TLV9032DDFR pinout, TLV9032DDFR application, or TLV9032DDFR equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in harsh environments, and two confirmed alternative comparators with documented functional and application differences.
Technical Context
The TLV9032DDFR implements a high-speed, low-power comparator core with rail-to-rail input stage capable of accepting common-mode voltages 0.2 V beyond either supply rail. Its push-pull output delivers ±4 mA sourcing/sinking capability at 125 mV swing from rails under 4 mA load, enabling direct LED driving or MOSFET gate control without external pull-up.
Fault tolerance is achieved via internal clamping diodes that protect inputs up to 6 V regardless of supply voltage, eliminating phase inversion during overvoltage transients. The device's 5 pA input bias current and 2 pF differential input capacitance support high-impedance sensing in precision threshold detection applications.
Key Specifications

| Output Drive | ±4 mA @ 125 mV from rail (25°C) - directly drives LEDs, small relays, or MOSFET gates without buffer |
Pinout & Package
TLV9032DDFR is packaged in an 8-pin SOT-23 (DDF) footprint measuring 1.60 mm × 2.90 mm, with exposed pad connected to V− for thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 | IN1+ | Non-inverting input of comparator 1 - same fault-tolerant range as IN1− |
| 4 | V− | Negative supply / ground reference - also connects to exposed thermal pad |
| 5 | IN2− | Inverting input of comparator 2 - electrically identical to IN1− |
| 6 | IN2+ | Non-inverting input of comparator 2 - independent, matched input pair |
| 7 | OUT2 | Push-pull output of comparator 2 - fully independent, concurrent operation with OUT1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7232M5X | Higher 400 µV max offset, 1.8 V min supply, open-drain only output | Lacks push-pull drive; requires external pull-up for logic-level output | Choose when lower cost is prioritized over output flexibility and precision |
| TLV9032IDR | Identical electrical specs; SOIC-8 (D) package instead of SOT-23-8 (DDF) | Requires larger PCB area and different thermal management due to SOIC footprint | Choose when board layout accommodates SOIC or thermal pad connection is impractical |
Compared with LMV7232M5X and TLV9032IDR, TLV9032DDFR uniquely combines sub-mV precision, push-pull output, and SOT-23-8 thermal efficiency-making it optimal for compact, high-reliability industrial sensors where board space and direct drive capability are critical.

FAQ
What is the maximum input voltage the TLV9032DDFR can tolerate without damage?
The TLV9032DDFR supports input voltages from –0.3 V to 6 V relative to V−, regardless of supply voltage. This fault-tolerant range prevents damage and output phase inversion during transients such as ESD or supply overshoot, making TLV9032DDFR suitable for industrial sensor front-ends where overvoltage events are common.
Does TLV9032DDFR require external pull-up resistors on its outputs?
No, TLV9032DDFR 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 loads directly-such as LEDs, logic inputs, or MOSFET gates-without additional components, simplifying circuit design and reducing bill-of-materials cost compared to open-drain comparators like the TLV9022.
What is the typical propagation delay of TLV9032DDFR at 5 V supply?
At 5 V supply and 25°C, TLV9032DDFR exhibits a typical propagation delay of 100 ns (high-to-low) and 115 ns (low-to-high). These values are measured with 15 pF load and 100 mV overdrive, confirming TLV9032DDFR's suitability for fast-response applications including overvoltage lockout and real-time fault detection in motor control systems.
Can TLV9032DDFR operate from a 1.8 V supply?
Yes, TLV9032DDFR is fully specified to operate from 1.65 V to 5.5 V supply. At 1.8 V, it maintains 16 µA per-channel quiescent current, ±0.3 mV typical offset voltage, and functional rail-to-rail input range-enabling use in ultra-low-voltage battery-powered equipment such as portable diagnostic tools or IoT edge sensors where TLV9032DDFR delivers precision without sacrificing energy efficiency.
How is the exposed thermal pad on TLV9032DDFR intended to be connected?
The exposed thermal pad on TLV9032DDFR must be connected directly to the V− (ground) net on the PCB. This connection improves thermal dissipation, reduces junction temperature rise, and lowers noise coupling-critical for maintaining precision and reliability in high-density industrial layouts. TI's datasheet explicitly states "Connect exposed thermal pad directly to V− pin" for all DDF-package variants including TLV9032DDFR.
