Product details
Overview
TLV2352ID from Texas Instruments is a dual low-voltage differential comparator IC designed for single-supply operation with rail-to-rail input capability down to ground, 120µA typical supply current at 3V, 200ns typical response time (for TLV2352IDR/PWR variants), and open-drain N-channel outputs requiring external pullup-used in battery-powered voltage monitoring and precision threshold detection circuits.
For engineers reviewing the TLV2352ID datasheet, TLV2352ID pinout, TLV2352ID application, or TLV2352ID equivalent, this page delivers verified package mapping (SOIC-8 D package), confirmed electrical specs (2V–8V supply, 5pA input bias, 10¹²Ω input impedance), thermal range (–40°C to 85°C), and two validated alternative comparators with documented functional distinctions.
Technical Context
The TLV2352ID implements two independent CMOS-based comparators with high-impedance inputs (10¹²Ω typical) and extremely low input bias current (5pA typical at 25°C), enabling direct interfacing with high-impedance sensors and reference dividers. Its common-mode input range includes ground, supporting true single-supply operation from as low as 2V.
Each comparator features an open-drain N-channel output stage, requiring an external pullup resistor to define logic-high level and enabling wired-AND configurations. It is fully characterized across –40°C to 85°C at both 3V and 5V supplies, with ESD protection rated at 1000V HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2V to 8V - supports direct integration into 3.3V and 5V systems, including coin-cell and Li-ion battery-powered designs. |
| Supply Current (Typ.) | 120µA at 3V - enables multi-year operation in ultra-low-power wake-up and monitoring circuits. |
| Input Bias Current (Typ.) | 5pA at 25°C - preserves accuracy in high-impedance sensor interfaces (e.g., photodiode, pH electrode). |
| Input Impedance (Typ.) | >10¹²Ω - minimizes loading on precision voltage dividers and reference networks. |
| Response Time (Typ.) | 200ns for TTL-level step (TLV2352IDR/PWR only) - suitable for fast edge-detection in digital control loops. |
| Common-Mode Input Range | Includes ground (0V) at VDD = 3V - allows direct sensing of signals referenced to system ground without level-shifting. |
| Output Type | Open-drain N-channel - supports flexible logic-level translation via external pullup and wired-AND bus topologies. |
Pinout & Package
TLV2352ID is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with standard 1.27mm pitch and 3.9mm body width. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Open-drain output of Comparator A - requires external pullup resistor to define HIGH level; sinks current when active. |
| 2 | IN– A | Inverting input of Comparator A - accepts voltage down to ground; high-impedance node for threshold reference. |
| 3 | IN+ A | Non-inverting input of Comparator A - accepts voltage down to ground; high-impedance node for signal sensing. |
| 4 | GND | Power ground reference - shared return path for both comparators and external pullup resistors. |
| 5 | IN+ B | Non-inverting input of Comparator B - electrically identical to Pin 3; supports independent dual-threshold detection. |
| 6 | IN– B | Inverting input of Comparator B - electrically identical to Pin 2; enables mirrored or differential pair configuration. |
| 7 | OUT B | Open-drain output of Comparator B - independently controllable; supports parallel or cascaded logic decisions. |
| 8 | VDD | Positive supply rail - powers both comparators; operates from 2V to 8V with no internal regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional from 2V supply - eliminates need for boost converters in 2-cell alkaline or single LiFePO₄ systems. |
| Ground-sensing input range | Common-mode extends to 0V - enables direct comparison of signals referenced to system ground without biasing. |
| Ultra-low input bias current | 5pA typical - prevents error drift in high-resistance divider networks used with precision references. |
| Open-drain output architecture | Supports mixed-voltage logic interfacing (e.g., 3.3V comparator driving 5V microcontroller interrupt line). |
| ESD robustness | 1000V HBM rating - reduces risk of field failure during board handling and assembly in non-ESD-controlled environments. |
Applications
| Battery Voltage Monitor | Threshold Detector for Sensor Outputs |
|---|---|

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 (125µA vs. 120µA), wider supply range (2.7V–5.5V), same SOIC-8 package. | Lacks ground-sensing input range (VICR starts at –0.1V, not 0V); unsuitable for true single-supply ground-referenced sensing. | Select LMV393IDR only if operating strictly within 2.7V–5.5V and ground-referenced input is not required. |
| TLV3702IDR | Lower input bias current (1pA), rail-to-rail input, but higher supply current (320µA), different pinout (SOIC-8, but OUT A/OUT B swapped). | Not pin-compatible; requires PCB redesign. Superior for femtoampere sensor interfaces but increases power budget by 2.7×. | Choose TLV3702IDR only when ultra-low input bias dominates design priority and layout revision is acceptable. |
Compared with TLV2352ID, LMV393IDR offers tighter supply voltage limits and slightly higher current draw but cannot sense down to ground, while TLV3702IDR delivers superior input bias performance at the cost of 2.7× higher quiescent current and non-pin-compatible layout-making TLV2352ID optimal for ground-referenced, ultra-low-power dual-threshold detection where pin compatibility matters.

FAQ
What is the operating temperature range for TLV2352ID?
The TLV2352ID is specified for operation from –40°C to +85°C. This industrial-grade temperature range is fully characterized at both 3V and 5V supply voltages, ensuring consistent performance in environments such as factory automation controllers and outdoor IoT nodes. The TLV2352ID does not support the extended –55°C to +125°C range-that specification applies only to the TLV2352M variant.
Does TLV2352ID support rail-to-rail input operation?
Yes, the TLV2352ID supports rail-to-rail input common-mode voltage range-including ground (0V)-when powered from 3V or 5V supplies. At VDD = 3V, the valid input range is 0V to 1.75V; at VDD = 5V, it extends to 0V to 3.75V. This enables direct interface with ground-referenced sensors and eliminates the need for input biasing networks in many single-supply designs.
Is TLV2352ID pin-compatible with TLV2352IDR?
Yes, TLV2352ID and TLV2352IDR share identical SOIC-8 (D) package dimensions, pinout, and electrical functionality. The "R" suffix denotes tape-and-reel packaging (2500 units per reel), while TLV2352ID refers to the same die and package in tube format. No PCB layout changes are required when migrating between these orderables.
What output configuration does TLV2352ID use, and how should it be interfaced?
TLV2352ID uses open-drain N-channel outputs for both comparators. Each output (Pins 1 and 7) must be pulled up externally-typically with a 4.7kΩ to 10kΩ resistor-to the desired logic HIGH voltage (e.g., 3.3V or 5V). This configuration allows wired-AND logic, mixed-voltage interfacing, and direct connection to microcontroller interrupt pins without level shifters.
Can TLV2352ID operate from a 2.0V supply, and what performance trade-offs apply?
Yes, TLV2352ID is fully specified to operate from 2.0V to 8.0V. At 2.0V, supply current remains low (~120µA typ.), input bias current stays at 5pA typ., and input common-mode range includes ground-but response time degrades to ~1.4µs (vs. 200ns at 3V/5V with TLV2352IDR/PWR variants), and output voltage swing is limited by the reduced VDD headroom. Use 2V only when speed is secondary to ultra-low power.
