Product details
Overview
TLV2352IDR from Texas Instruments is a dual low-voltage differential comparator IC designed for single-supply operation with 2.7V to 8V supply range, 200ns typical response time (TTL-level step), 120µA typical supply current at 3V, and open-drain N-channel outputs requiring external pullup. It enables precision threshold detection in battery-powered sensor interfaces and portable power management systems.
For engineers reviewing the TLV2352IDR datasheet, TLV2352IDR pinout, TLV2352IDR application, or TLV2352IDR equivalent, key selection criteria include its 5pA typical input bias current, rail-to-rail common-mode input range including ground, 10¹²Ω typical input impedance, and SOIC-8 packaging optimized for space-constrained industrial and portable designs.
Technical Context
The TLV2352IDR implements two independent CMOS-based comparators with open-drain outputs, supporting wired-AND logic configurations via external pullup resistors. Its input stage features ultra-high impedance and sub-picoampere bias current, enabling direct interfacing with high-impedance sensors and reference sources without loading.
Characterized across –40°C to 85°C, the device operates down to 2.7V (not 2V like other variants), delivers 200ns propagation delay under 10mV overdrive at 3V/5V, and maintains 1mV typical input offset voltage - all verified per TI's production test flow for the D-package tape-and-reel variant.

IC Role / Device Role / Timing Role: Dual comparator provides hysteresis-enabled undervoltage lockout (UVLO) and precise threshold comparison using internal reference or resistor divider. Use Value: 120µA quiescent current extends battery life; 5pA input bias avoids measurement drift in high-resistance divider networks. | Use Scenario: Monitoring shunt voltage in a 12V automotive accessory module to disable load if current exceeds 5A. IC Role / Device Role / Timing Role: Compares amplified shunt voltage against fixed reference; open-drain outputs drive MOSFET gate driver enable line. Use Value: 200ns response ensures sub-microsecond fault reaction; rail-to-ground input range accommodates shunt placed on low side. |
| Window Comparator | Zero-Crossing Detector |
Use Scenario: Validating that analog sensor output remains within ±2% tolerance band in industrial temperature transmitters. IC Role / Device Role / Timing Role: One comparator monitors upper limit, the other lower limit; wired-AND output asserts only when both thresholds are satisfied. Use Value: Independent channels eliminate need for external logic; 5mV max VIO ensures tight window definition without calibration. | Use Scenario: Converting sine-wave AC line voltage into clean square wave for phase-controlled dimmer timing in smart lighting. IC Role / Device Role / Timing Role: Compares AC signal against 0V reference; open-drain output pulls up to 3.3V MCU I/O with minimal propagation skew.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV393IDR | Higher supply current (180µA typ), 300ns response, 7mV VIO max - less precise, slower, higher power | Acceptable where 5mV threshold accuracy and sub-250ns timing are not critical | Choose LMV393IDR only if cost sensitivity outweighs performance requirements and existing layout uses same SOIC-8 footprint |
| TLV3702IDR | Lower supply current (85µA typ), rail-to-rail output, 1.5mV VIO max - superior precision and efficiency | Requires no external pullup; supports push-pull logic directly but lacks wired-AND capability | Prefer TLV3702IDR when driving MCU GPIO directly or minimizing external components; avoid if wired-AND bus sharing is needed |
Compared with LMV393IDR, TLV2352IDR offers tighter offset and faster response at lower current; versus TLV3702IDR, it trades rail-to-rail output flexibility for wired-AND compatibility and proven robustness in legacy industrial designs.

FAQ
What is the minimum operating supply voltage for TLV2352IDR?
The TLV2352IDR is specified for operation from 2.7V to 8V - unlike some TLV2352 variants rated down to 2V, this D-package tape-and-reel version requires ≥2.7V per TI's characterization data in Sections 5.2 and 5.5. Operating below 2.7V may result in undefined propagation delay, increased offset, or failure to meet output swing specifications. Always verify functionality at the intended VDD using the recommended conditions table in the official TLV2352IDR datasheet.
Does TLV2352IDR support rail-to-rail input common-mode range?
TLV2352IDR supports a common-mode input voltage range that includes ground (0V) but does not extend to VDD - at 3V supply, VICR is 0V to 1.75V; at 5V, it is 0V to 3.75V. This ground-inclusive range enables direct low-side sensing without level shifters, but high-side signals near VDD require attenuation or biasing. The specification is confirmed in Section 5.2 Recommended Operating Conditions and Table 5.3 Electrical Characteristics for TLV2352I.
Can TLV2352IDR outputs be wire-OR'd together?
Yes - TLV2352IDR features open-drain N-channel outputs (Pins 3 and 7), allowing multiple comparators or devices to share a single pullup resistor and implement positive-logic wired-AND functionality. This is explicitly stated in the Description section and validated in Figure 4-1 pin configuration. Ensure external pullup value is selected to meet rise time and fan-out requirements while staying within the 20mA absolute maximum output current rating.
What is the guaranteed input offset voltage for TLV2352IDR over temperature?
The TLV2352IDR has a maximum input offset voltage of 7mV across the full operating range of –40°C to 85°C, with 5mV maximum at 25°C (Section 5.3). This is measured per TI's production test flow for the TLV2352I grade. The 7mV worst-case value ensures predictable threshold accuracy in temperature-varying environments such as industrial enclosures or automotive cabins, provided the application's required hysteresis exceeds this margin.
Is TLV2352IDR pin-compatible with other TLV2352 variants?
TLV2352IDR shares the same SOIC-8 (D) package and pinout as TLV2352ID and TLV2352IP, as confirmed in Figure 4-1 and Package Option Addendum. However, electrical differences exist: TLV2352IDR is characterized for 2.7–8V operation and 200ns response (10mV overdrive), whereas TLV2352ID is not explicitly rated for the 2.7V lower bound. Substituting without verifying supply range and timing margins may lead to marginal performance in low-voltage applications.
