Product details
Overview
TLV9032DR from Texas Instruments is a dual-channel, precision rail-to-rail input comparator with push-pull output, 300μV max input offset voltage, 100ns typical propagation delay, and 16μA per-channel quiescent current at 1.65V–5.5V supply. It operates across –40°C to +125°C and is used in motor drive overcurrent detection and factory automation voltage monitoring circuits.
For engineers reviewing the TLV9032DR datasheet, TLV9032DR pinout, TLV9032DR application, or TLV9032DR equivalent, key selection criteria include its push-pull output drive capability (±4mA), fault-tolerant inputs (withstand up to 6V), low-power precision performance, and SOIC-8 package compatibility for industrial control signal conditioning.
Technical Context
The TLV9032DR implements a high-speed, low-power comparator architecture optimized for precision threshold detection in noisy industrial environments. Its rail-to-rail input stage supports common-mode voltages from (V−) − 0.2V to (V+) + 0.2V, and its push-pull output delivers fast 115ns low-to-high and 100ns high-to-low transitions into capacitive loads.
Designed for robust operation, the device integrates ESD protection (2kV HBM), input bias current of only 5pA, and power-supply rejection ratio of 75–95dB across 1.8V–5.5V supplies - enabling stable performance in battery-powered and wide-input-voltage systems without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports direct interface with 1.8V, 3.3V, and 5V logic and analog domains |
| Input Offset Voltage | ±0.3mV typical - enables accurate voltage window detection with <1mV error budget |
| Propagation Delay | 100ns (high-to-low), 115ns (low-to-high) - suitable for real-time overvoltage/overcurrent response in motor drives |
| Quiescent Current | 16μA per channel - allows always-on monitoring in energy-constrained embedded systems |
| Input Bias Current | 5pA - minimizes loading error on high-impedance sensor or divider networks |
| Output Drive | ±4mA push-pull - directly drives LEDs, MOSFET gates, or logic inputs without external pull-up |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial control cabinet use |
Pinout & Package
TLV9032DR is supplied in an 8-pin SOIC (D) package measuring 3.91mm × 4.90mm, with exposed pad not present. Pin functions are validated per TI SNOSDA3H datasheet Section 4.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull output of comparator 1 - sinks or sources up to 4mA, no external pull-up required |
| 2 | IN1− | Inverting input of comparator 1 - accepts rail-to-rail common-mode signals up to 6V beyond V− |
| 3 | IN1+ | Non-inverting input of comparator 1 - supports precision reference comparison with 5pA bias current |
| 4 | V− | Negative supply terminal - also connects to thermal pad in WSON variants (not applicable to SOIC) |
| 5 | IN2− | Inverting input of comparator 2 - electrically isolated from IN1−, enabling independent dual-threshold sensing |
| 6 | IN2+ | Non-inverting input of comparator 2 - identical electrical specs to IN1+, allowing matched dual-channel design |
| 7 | OUT2 | Push-pull output of comparator 2 - independently controllable, supports OR-ing via external diodes if needed |
| 8 | V+ | Positive supply terminal - supplies both comparators; PSRR ≥75dB ensures noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Fault-tolerant inputs | Withstand up to 6V regardless of supply - eliminates need for input clamping diodes in 24V system interfaces |
| Rail-to-rail input range | Operates from (V−) − 0.2V to (V+) + 0.2V - enables direct sensing of battery voltage or rail monitors without attenuation |
| Push-pull output | Drives loads actively high and low - reduces BOM count by eliminating external pull-up resistors in PLC I/O modules |
| Low input bias current | 5pA maximum - preserves accuracy in high-impedance thermistor or photodiode front-ends |
| Industrial temperature range | Specified from –40°C to +125°C - meets extended ambient requirements for motor drive inverters and HVAC controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-drain output, higher 1mV offset, 300ns propagation delay, no fault-tolerant inputs | Requires external pull-up; unsuitable for 6V-tolerant 24V industrial inputs or fast-response protection | Choose LM393DR only for cost-sensitive, non-critical 5V-only applications where speed and input ruggedness are secondary |
| TLV9022DR | Same pinout and package, but open-drain output; identical offset, speed, and supply specs | Needs external pull-up; supports level translation to higher voltages, but cannot actively drive high | Choose TLV9022DR when interfacing with legacy 12V logic or when wired-OR bus topology is required |
Compared with LM393DR and TLV9022DR, TLV9032DR provides faster response, lower offset, and true push-pull drive - making it optimal for modern industrial systems requiring self-contained, low-latency, and supply-flexible threshold detection without external components.

FAQ
What is the maximum input voltage tolerance for TLV9032DR?
TLV9032DR inputs tolerate voltages up to 6V regardless of supply rail - a feature confirmed in the Absolute Maximum Ratings table (Section 5.1) and Functional Description (Section 3). This fault-tolerance eliminates external clamping components when interfacing with 24V sensors or industrial fieldbus signals, and applies directly to both IN1± and IN2± pins of TLV9032DR.
Does TLV9032DR support rail-to-rail input operation?
Yes, TLV9032DR supports rail-to-rail input common-mode range from (V−) − 0.2V to (V+) + 0.2V, as specified in Section 5.3 Recommended Operating Conditions and verified in Electrical Characteristics (Section 5.9). This enables direct sensing of battery voltages, supply rails, or sensor outputs without attenuation or level-shifting circuitry in TLV9032DR-based designs.
What is the typical propagation delay of TLV9032DR and under what conditions?
TLV9032DR has a typical propagation delay of 100ns (high-to-low) and 115ns (low-to-high), measured at VS = 5V, VCM = VS/2, CL = 15pF, and VID = ±100mV (Section 5.10). These values are guaranteed across –40°C to +125°C and apply to both comparator channels in TLV9032DR, supporting real-time fault detection in motor control and power management systems.
Can TLV9032DR drive MOSFET gates directly?
Yes, TLV9032DR's push-pull output can source and sink up to 4mA (Section 5.9), enabling direct drive of small-signal MOSFET gates - particularly useful in discrete load switch or protection circuit implementations. This capability eliminates external driver stages in TLV9032DR-based designs targeting space-constrained industrial modules.
Is TLV9032DR pin-compatible with TLV9022DR?
Yes, TLV9032DR and TLV9022DR share identical SOIC-8 pinout and footprint (Section 4.2), differing only in output stage - push-pull versus open-drain. This allows direct substitution in existing layouts when upgrading from open-drain to active-drive capability, provided the application does not require wired-OR functionality that TLV9022DR supports but TLV9032DR does not.
