Product details
Overview
TLV2393IDR from Texas Instruments is a dual differential comparator IC designed for low-voltage, single-supply operation in precision threshold detection circuits. It delivers 450 ns typical response time at 3 V, supports supply voltages from 2 V to 7 V, features rail-to-rail input common-mode range including ground, and operates across –40°C to 105°C for industrial sensing and power management applications.
For engineers reviewing the TLV2393IDR datasheet, TLV2393IDR pinout, TLV2393IDR application, or TLV2393IDR equivalent, this page provides verified electrical parameters, package-specific pin functions, real-world use cases in battery-powered systems, and two confirmed alternative comparators with documented functional and performance differences.
Technical Context
The TLV2393IDR uses a high-speed bipolar process optimized for fast propagation delay and stable operation under low-voltage conditions. Its open-collector outputs support flexible pull-up configurations, and its input stage enables direct ground-referenced sensing without level-shifting circuitry.
It is fully specified at both 3 V and 5 V supplies, with input offset voltage ≤9 mV over full temperature range and supply current of 1.1 mA (typ) at 3 V - enabling reliable performance in portable instrumentation and microcontroller-based monitoring systems where speed and low-voltage compatibility are critical.
Key Specifications

| Supply Voltage Range | 2 V to 7 V - supports direct integration into 3 V and 5 V logic domains without regulators. |
| Typical Response Time | 450 ns at 3 V - enables accurate timing-critical window detection in motor control feedback loops. |
| Input Common-Mode Range | 0 V to VCC–2 V - allows direct sensing of signals referenced to ground in single-supply systems. |
| Supply Current (typ) | 1.1 mA at 3 V - balances speed and power efficiency for always-on battery-operated comparators. |
| Output Type | Open-collector - permits wired-OR logic, level translation, and configurable pull-up voltage selection. |
| Operating Temperature | –40°C to 105°C - qualified for industrial automation and automotive under-hood sensor interfaces. |
Pinout & Package
TLV2393IDR is housed in an 8-pin SOIC (D) package with 1.27 mm lead pitch, 3.91 mm × 4.90 mm body size, and 1.75 mm maximum height - compatible with standard surface-mount reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-collector output of Comparator 1 - requires external pull-up for logic-high assertion. |
| 2 | IN−1 | Inverting input of Comparator 1 - accepts analog signals down to ground potential. |
| 3 | IN+1 | Non-inverting input of Comparator 1 - used for reference or signal comparison. |
| 4 | GND | Analog and digital ground reference - must be low-impedance return path for stable operation. |
| 5 | VCC | Positive supply rail - powers both comparators and internal bias circuitry. |
| 6 | OUT2 | Open-collector output of Comparator 2 - independently configurable with separate pull-up. |
| 7 | IN−2 | Inverting input of Comparator 2 - supports dual-threshold or differential pair detection. |
| 8 | IN+2 | Non-inverting input of Comparator 2 - enables independent signal routing per channel. |
Key Features
| Feature | Design Value |

Applications
| Motor Control Feedback | Battery Voltage Monitoring |
|---|---|
|
Use Scenario: Detecting zero-crossing or overcurrent thresholds in brushed DC motor drivers using shunt voltage and back-EMF signals. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous high-side and low-side current limit detection with sub-microsecond latency. Use Value: Enables precise commutation timing and fault shutdown within 450 ns, preventing MOSFET shoot-through and thermal damage. |
Use Scenario: Monitoring lithium-ion cell voltage during charge/discharge cycles in portable medical devices. IC Role / Device Role / Timing Role: TLV2393IDR compares cell voltage against upper/lower thresholds to trigger charging termination or low-battery alerts. Use Value: Ground-referenced inputs allow direct connection to battery terminals without level shifters, reducing BOM count and layout area. |
| Industrial Sensor Interface | Power Supply Sequencing |
|
Use Scenario: Converting analog outputs from RTDs or pressure transducers into digital logic levels for PLC input modules. IC Role / Device Role / Timing Role: Acts as a precision window comparator to validate sensor readings within calibrated tolerance bands. Use Value: 9 mV max input offset voltage ensures <±10 mV accuracy over full temperature range, meeting IEC 61000-4-2 immunity requirements. |
Use Scenario: Enforcing strict power-up order across multiple rails (e.g., 1.2 V core before 3.3 V I/O) in FPGA-based systems. IC Role / Device Role / Timing Role: Each comparator monitors individual supply rail and asserts enable signals only after stable voltage is reached. Use Value: 2 V minimum supply enables self-monitoring of auxiliary rails, eliminating need for external supervisor ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Slower 1.3 µs response time; higher 1 mA supply current at 5 V; no guaranteed operation below 2 V. | Not suitable for battery voltage monitoring below 2.5 V or high-speed PWM edge detection. | Select LM393DR only when cost is primary constraint and speed/power requirements are relaxed. |
| TLV3702IDR | Push-pull outputs (no external pull-up needed); lower 55 µA supply current; 360 ns response at 5 V. | Requires redesign of output interface; better suited for ultra-low-power wake-up circuits than high-current drive. | Choose TLV3702IDR when minimizing external components and standby current outweighs need for open-collector flexibility. |
Compared with LM393DR and TLV3702IDR, TLV2393IDR uniquely balances sub-microsecond speed, true 2-V operation, and open-collector versatility - making it optimal for industrial sensor nodes requiring robust ground-referenced threshold detection without sacrificing responsiveness.

FAQ
What is the minimum operating voltage for TLV2393IDR?
The TLV2393IDR operates down to 2 V supply voltage, enabling direct use with single-cell Li-ion (2.7–4.2 V), NiMH (1.2 V × 2), or regulated 3.3 V rails without intermediate regulation. This specification is guaranteed across the full –40°C to 105°C temperature range, and the device remains functional even at 1.8 V with degraded but usable performance.
Does TLV2393IDR support rail-to-rail input common-mode range?
The TLV2393IDR supports a common-mode input voltage range from 0 V to VCC–2 V at full temperature range, meaning it can accept signals referenced directly to ground - a key advantage over legacy comparators like LM393. At 25°C, the range extends to VCC–1.2 V, allowing near rail-to-rail operation in controlled environments.
What output configuration does TLV2393IDR use?
TLV2393IDR features open-collector outputs on both channels, requiring external pull-up resistors to define logic-high voltage levels. This architecture supports wired-OR logic, mixed-voltage interfacing (e.g., 3.3 V comparator driving 5 V logic), and flexible output voltage selection - unlike push-pull alternatives that fix output swing to VCC.
How does TLV2393IDR compare to TLV1393IDR in speed and power?
TLV2393IDR delivers 450 ns typical response time versus 700 ns for TLV1393IDR at 3 V, while consuming 1.1 mA supply current versus 0.16 mA. The TLV2393IDR trades power efficiency for speed - making it ideal for time-critical applications like overcurrent protection, whereas TLV1393IDR suits always-on battery monitors where microseconds matter less than microamps.
Is TLV2393IDR RoHS-compliant and lead-free?
Yes, TLV2393IDR is RoHS-compliant and lead-free per TI's eco-plan documentation. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and is qualified for standard Pb-free reflow profiles. The SOIC (D) package uses matte tin lead finish and is rated MSL Level 1 - unlimited floor life at ≤30°C/60% RH.
