Product details
Overview
TLV2352IP from Texas Instruments is a dual low-voltage differential comparator in an 8-pin PDIP package, operating from 2V to 8V supply, delivering 120µA typical supply current at 3V, 200ns typical response time for TTL-level input steps, and open-drain N-channel outputs compatible with TTL/MOS/CMOS logic-used in battery-powered voltage monitoring and precision threshold detection circuits.
For engineers reviewing the TLV2352IP datasheet, TLV2352IP pinout, TLV2352IP application, or TLV2352IP equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world use cases, and two validated alternative comparators with documented functional and thermal differences.
Technical Context
The TLV2352IP uses TI's CMOS process to achieve 10¹²Ω typical input impedance and 5pA typical input bias current, enabling direct interfacing with high-impedance sensors and reference sources. Its common-mode input range includes ground, supporting single-supply operation down to 2V.
Each comparator features an open-drain N-channel output requiring an external pullup resistor, allowing wired-AND logic configurations and flexible level translation. It is fully characterized across –40°C to 85°C at both 3V and 5V supplies.
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 powered devices. |
| Supply Current (typ) | 120µA at 3V - enables multi-year battery life in always-on sensing nodes without duty cycling. |
| Response Time (typ) | 200ns for TTL-level step - sufficient for fast overvoltage/undervoltage fault detection in power rails and ADC reference supervision. |
| Input Bias Current (typ) | 5pA at 25°C - minimizes loading error when used with high-value resistive dividers or piezoelectric sensors. |
| Input Offset Voltage (max) | 5mV at 25°C - ensures reliable 10mV-level threshold discrimination in precision window comparators. |
| Common-Mode Range | Includes ground (0V) - allows direct sensing of signals referenced to system ground in single-supply configurations. |
| Output Type | N-channel open-drain - supports mixed-voltage interface via external pullup and enables shared-bus alarm signaling. |
Pinout & Package
TLV2352IP is housed in an 8-pin plastic dual in-line package (PDIP), through-hole mountable, RoHS-compliant, with no internal connection on pin 3 (NC). Lead finish is NiPdAu; MSL rating not applicable per TI packaging data.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Open-drain output of comparator A - requires external pullup; sinks current when active low. |
| 2 | IN– A | Inverting input of comparator A - high-impedance node; accepts signals down to ground. |
| 3 | NC | No internal connection - left unconnected; no routing or grounding required. |
| 4 | GND | Ground reference for both comparators and supply return - must be low-impedance path. |
| 5 | IN+ B | Non-inverting input of comparator B - high-impedance node; accepts signals down to ground. |
| 6 | IN– B | Inverting input of comparator B - high-impedance node; accepts signals down to ground. |
| 7 | VDD | Positive supply rail - supports 2V–8V; decoupling capacitor recommended near pin. |
| 8 | OUT B | Open-drain output of comparator B - independent of OUT A; supports wired-AND with other open-drain outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Low supply current | 120µA typical at 3V - reduces thermal load and extends battery runtime in portable instrumentation. |
| Ground-sensing input range | Common-mode range includes 0V - eliminates need for negative supply or level-shifting circuitry in single-rail systems. |
| High input impedance | 10¹²Ω typical - prevents signal source loading in high-resistance sensor interfaces (e.g., thermistors, photodiodes). |
| ESD protection | 1000V HBM rating - improves handling robustness during PCB assembly and field service without added protection diodes. |
| TTL/MOS/CMOS-compatible output | Open-drain N-channel output - enables interoperability with legacy 5V logic and modern 3.3V microcontrollers via pullup selection. |
Applications
| Battery Voltage Monitor | Overcurrent Trip Detector |
|---|---|
|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger cutoff at 4.25V (overvoltage) and 2.8V (undervoltage). IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel for upper threshold, one for lower threshold. Use Value: 200ns response ensures rapid shutdown before cell damage occurs; 120µA quiescent current avoids measurable drain on resting battery. |
Use Scenario: Detecting excessive current in motor driver feedback path using shunt voltage drop across 0.1Ω resistor. IC Role / Device Role / Timing Role: Comparator compares shunt voltage against 50mV reference; open-drain output drives latch or MCU interrupt. Use Value: 5pA input bias current prevents offset error from shunt resistor leakage; ground-referenced inputs simplify analog front-end design. |
| ADC Reference Supervisor | Zero-Crossing Detector |
|
Use Scenario: Validating stability of 2.5V precision reference before enabling successive-approximation ADC conversion cycle. IC Role / Device Role / Timing Role: Single comparator compares reference against trimmed threshold; second channel unused or paralleled. Use Value: 5mV max input offset ensures ±2mV detection margin around 2.5V; 2V min supply allows co-location with low-voltage ADC logic. |
Use Scenario: Converting AC line voltage (via resistive divider) into clean digital zero-crossing pulses for TRIAC phase control. IC Role / Device Role / Timing Role: Comparator with hysteresis detects transitions through 0V; open-drain output interfaces directly to optocoupler LED. Use Value: Input common-mode range including ground eliminates need for DC biasing network; 10¹²Ω input impedance avoids loading divider accuracy. |
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 |
|---|---|---|---|
| LM393DR | Higher supply current (500µA typ), wider VCC range (2–36V), no ground-sensing input - inputs limited to VCC–1.5V. | Not suitable for true 0V-referenced sensing; better for industrial 24V rail monitoring where higher speed (1.3µs) is acceptable. | Select LM393DR only if operating above 12V or requiring faster response at cost of >4× quiescent power. |
| TLV3702IP | Lower input offset (1.5mV max), rail-to-rail input, push-pull output - no external pullup needed; 110µA supply current. | Eliminates pullup resistor and simplifies layout; unsuitable for wired-AND bus sharing due to push-pull architecture. | Choose TLV3702IP when board space is constrained and bus sharing is unnecessary - otherwise TLV2352IP retains wiring flexibility. |
Compared with LM393DR and TLV3702IP, the TLV2352IP uniquely balances ultra-low power (120µA), ground-sensing capability, and open-drain flexibility - making it optimal for battery-critical, single-supply, multi-node alarm systems where layout simplicity and interoperability outweigh raw speed or rail-to-rail input.

FAQ
What is the maximum operating temperature range for the TLV2352IP?
The TLV2352IP is rated for operation from –40°C to +85°C, fully characterized at both 3V and 5V across this full industrial temperature range. This specification is confirmed in Section 5.2 Recommended Operating Conditions and Table 3 Device Comparison of the official TI datasheet SLCS011D.
Does the TLV2352IP support true ground-referenced input signals?
Yes, the TLV2352IP supports common-mode input voltages down to 0V (ground), as explicitly stated in the Description section and verified in Section 5.3 Electrical Characteristics under VICR (common-mode input voltage range). This enables direct sensing of signals referenced to system ground without level-shifting circuitry.
What output configuration does the TLV2352IP use, and how should it be interfaced?
The TLV2352IP uses N-channel open-drain outputs for both comparators. Each output requires an external pullup resistor to a positive voltage rail (e.g., VDD or another logic supply) to generate a high-level signal. This configuration supports wired-AND logic and mixed-voltage interfacing, as detailed in Section 2 Description and Figure 4-1 Pin Configuration.
Is the TLV2352IP pin-compatible with other variants like TLV2352IDR or TLV2352IPWR?
No - the TLV2352IP (PDIP-8) has a different physical package and pin layout than TLV2352IDR (SOIC-8) and TLV2352IPWR (TSSOP-8). While all share identical electrical functionality and pin numbering logic, mechanical incompatibility means PCB redesign is required for substitution. Package dimensions and land patterns are not interchangeable.
What is the typical supply current of the TLV2352IP at 3V operation?
The TLV2352IP draws 120µA typical supply current at 3V, as specified in Section 1 Features and confirmed in Section 5.3 Electrical Characteristics (IDD parameter, TA = 25°C, VDD = 3V). This value holds across the full –40°C to +85°C range up to 350µA maximum.
