Overview
TLV2352IPWLE from Texas Instruments is a dual low-voltage differential comparator IC designed for single-supply operation down to 2V, featuring 120µA typical supply current at 3V, 5pA typical input bias current, and open-drain N-channel outputs requiring external pullup. It operates across –40°C to 85°C and targets precision threshold detection in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2352IPWLE datasheet, TLV2352IPWLE pinout, TLV2352IPWLE application, or TLV2352IPWLE equivalent, this page delivers verified electrical specs, TSSOP-8 package details, TTL/MOS/CMOS-compatible output behavior, ESD-protected design context, and real-world comparator selection guidance - all tied explicitly to the TLV2352IPWLE ordering variant.
Technical Context
The TLV2352IPWLE implements two independent CMOS-based comparators with rail-to-rail input common-mode range including ground, enabling direct sensing of signals referenced to system ground. Its open-drain outputs support wired-AND logic and flexible level translation via external pullup resistors.
It is fully characterized at 3V and 5V over –40°C to 85°C, supports supply voltages from 2V to 8V (not limited to 2.7V minimum), and delivers 200ns typical response time for TTL-level input steps under specified load conditions (RL = 5.1kΩ, CL = 15pF).
Key Specifications

Use Value: Matched input offset (≤5mV) ensures tight window accuracy; open-drain outputs enable OR'ing of fault signals. |
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), wider VDD range (2.7V–5.5V), no 2V operation; push-pull output (no external pullup needed). | Less suitable for sub-2.7V battery systems; eliminates need for pullup resistors but lacks wired-AND capability. | Choose LMV393IDR when push-pull outputs simplify board layout and supply is ≥2.7V. |
| TLV3702IPWR | Lower input bias current (0.1pA), rail-to-rail output, higher speed (1.5µs response), but higher supply current (1.25µA). | Better for ultra-high-impedance sources and faster transitions; unsuitable for µA-level power budgets. | Choose TLV3702IPWR when femtoampere-level bias and rail-to-rail output swing outweigh power constraints. |
Compared with TLV2352IPWLE, LMV393IDR trades ultra-low power for push-pull convenience and tighter supply limits, while TLV3702IPWR delivers superior precision and speed at >10× higher current - making TLV2352IPWLE optimal for long-life, ground-sensing, open-drain–dependent designs.

FAQ
What is the minimum operating supply voltage for TLV2352IPWLE?
The TLV2352IPWLE operates down to 2V, confirmed in the Recommended Operating Conditions table (Section 5.2). This distinguishes it from variants like TLV2352IDR and TLV2352IPWR, which specify a 2.7V minimum - a key differentiator for coin-cell or two-alkaline-cell applications where TLV2352IPWLE remains functional below 2.7V.
Does TLV2352IPWLE support rail-to-rail input common-mode range?
Yes, the TLV2352IPWLE supports a common-mode input voltage range that includes ground (0V) up to VDD – 1.5V at 3V supply, per Section 5.3 Electrical Characteristics. This allows direct comparison of signals referenced to system ground without level-shifting circuitry - a core feature explicitly validated for the TLV2352I grade used in TLV2352IPWLE.
What is the output configuration of TLV2352IPWLE and how does it affect circuit design?
TLV2352IPWLE features N-channel open-drain outputs requiring external pullup resistors to establish high-level voltage. This configuration enables wired-AND logic, level translation across voltage domains, and compatibility with TTL/MOS/CMOS loads - confirmed in the Description section and Pin Configuration diagrams. No internal pullup exists; omission of the external resistor results in undefined high-state behavior.
Is TLV2352IPWLE pin-compatible with other TLV2352 variants in TSSOP-8?
Yes, TLV2352IPWLE shares identical TSSOP-8 (PW) pinout and footprint with TLV2352IPWR and TLV2352IPW, as shown in Figure 4-3 of the datasheet. All PW-package variants use the same mechanical drawing, terminal numbering, and function mapping - enabling drop-in replacement where temperature grade and characterization match system requirements.
What is the guaranteed maximum input offset voltage for TLV2352IPWLE over temperature?
The TLV2352IPWLE (I-grade) has a guaranteed maximum input offset voltage of 7mV across the full operating range of –40°C to 85°C, per Section 5.3 Electrical Characteristics TLV2352I. At 25°C, the limit is tighter: 5mV max. This parameter directly impacts threshold accuracy in precision detection circuits and is validated for the TLV2352I temperature grade shipped in TLV2352IPWLE.
