Product details
Overview
TLC3702IPWRG4 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage, ±8 mA output drive capability, and 2.7 μs typical propagation delay (tPLH) at 5-mV overdrive - designed for low-power sensing and threshold-detection circuits in industrial control and battery-powered instrumentation.
For engineers reviewing the TLC3702IPWRG4 datasheet, TLC3702IPWRG4 pinout, TLC3702IPWRG4 application, or TLC3702IPWRG4 equivalent, this page delivers verified electrical specs, temperature-rated performance (−40°C to 85°C), package mapping (TSSOP-8), and real-world comparator use cases - all grounded in TI's SLCS013E datasheet revision March 2012.
Technical Context
The TLC3702IPWRG4 implements two independent comparators using Texas Instruments' LinCMOS™ process, enabling stable input offset voltage (<5 mV) across wide common-mode ranges (0 V to VDD − 1.5 V) and high CMRR (84 dB) without external trimming. Its push-pull output stage eliminates need for pullup resistors, directly driving capacitive loads up to 50 pF while maintaining fast response.
It operates from a single 3 V to 16 V supply, supports TTL- and CMOS-compatible logic levels, and integrates on-chip ESD protection rated to 2 kV HBM - making it suitable for noisy industrial environments where rail-to-rail input operation and micropower consumption (18–65 μA total IDD) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct interface with 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures reliable detection of small analog signals above noise floor in precision threshold applications. |
| Propagation Delay (tPLH) | 2.7 μs typ at 5-mV overdrive - supports sub-microsecond decision timing in fast-response monitoring circuits. |
| Output Drive Capability | ±8 mA - sufficient to directly drive LEDs, logic inputs, or small MOSFET gates without external buffers. |
| Quiescent Supply Current | 18–65 μA (−40°C to 85°C) - enables multi-year battery life in always-on sensor nodes and portable equipment. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows direct sensing of signals referenced to ground or near-rail voltages without attenuation. |
| ESD Protection | 2 kV HBM - meets industrial handling requirements and reduces need for external TVS components. |
Pinout & Package
TLC3702IPWRG4 is housed in an 8-pin TSSOP (PW) package with exposed thermal pad, pin-compatible with industry-standard SOIC-8 footprints but offering 30% smaller board area. Pin numbering follows standard JEDEC TSSOP convention (pin 1 marked by dot or bevel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull CMOS output of comparator 1 - sinks or sources current without external pullup; logic-high ≈ VDD, logic-low ≈ GND. |
| 2 | IN1− | Inverting input of comparator 1 - accepts differential input signals up to VDD − 1.5 V; high-impedance (5 pA bias current). |
| 3 | IN1+ | Non-inverting input of comparator 1 - same voltage range and impedance as IN1−; used for reference or signal input. |
| 4 | GND | Analog/digital ground reference - must be connected to system ground plane; shared return for both comparators. |
| 5 | VDD | Positive supply rail - powers both comparators; decoupling capacitor (0.1 μF) required within 5 mm of pin. |
| 6 | OUT2 | Push-pull CMOS output of comparator 2 - electrically identical to OUT1; supports independent logic-level outputs. |
| 7 | IN2− | Inverting input of comparator 2 - fully isolated from comparator 1; no crosstalk under normal operating conditions. |
| 8 | IN2+ | Non-inverting input of comparator 2 - matches IN1+ in performance; enables dual-threshold or window-comparator topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables simultaneous monitoring of two thresholds (e.g., overvoltage/undervoltage) in one compact footprint. |
| Push-pull CMOS output stage | Eliminates external pullup resistors - saves PCB space, reduces BOM count, and cuts static power by up to 100 μW per channel. |
| LinCMOS™ process technology | Delivers <5 mV input offset voltage with <1 pA input bias current - critical for high-impedance sensor interfaces like thermistors or photodiodes. |
| Wide temperature rating | Specified from −40°C to +85°C - qualified for industrial automation, motor drives, and outdoor environmental monitoring. |
| Single-supply operation | Operates from 3 V to 16 V - compatible with Li-ion, 5 V USB, and 12 V automotive auxiliary rails without regulators. |
Applications
| Overvoltage Protection Circuit | Battery Charge State Monitor |
|---|---|
Use Scenario: Detecting when a 12 V battery exceeds 12.8 V to disable charging and prevent electrolyte gassing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-collector output, higher supply current (500 μA), wider offset (7 mV max), no ESD rating specified. | Requires external pullup resistor; unsuitable for direct TTL/CMOS interfacing or low-power designs. | Choose LM393DR only if cost is primary constraint and open-collector flexibility (e.g., wired-OR bus) is needed. |
| TLC3702CDR | Same die, commercial temp range (0°C to 70°C), D-package (SOIC-8), no thermal pad. | Limited to office/indoor consumer electronics; not rated for extended industrial ambient conditions. | Select TLC3702CDR only for non-critical, temperature-stable environments where cost and legacy SOIC layout compatibility outweigh reliability needs. |
Compared with LM393DR and TLC3702CDR, the TLC3702IPWRG4 offers superior micropower operation (18 μA vs 500 μA), guaranteed industrial temperature support, and integrated push-pull outputs - making it the optimal choice for battery-powered and harsh-environment sensing where board space, power, and reliability are jointly constrained.

FAQ
What is the maximum operating temperature for the TLC3702IPWRG4?
The TLC3702IPWRG4 is characterized for continuous operation from −40°C to +85°C, meeting industrial temperature grade specifications. This range is validated per TI's SLCS013E datasheet and applies across the full 3 V to 16 V supply range with no derating required up to 85°C ambient.
Does the TLC3702IPWRG4 require external pullup resistors on its outputs?
No - the TLC3702IPWRG4 features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pullup resistors. This reduces power dissipation, saves board space, and simplifies design compared to open-collector comparators like the LM393.
Can the TLC3702IPWRG4 operate from a 3.3 V supply?
Yes - the TLC3702IPWRG4 supports single-supply operation from 3 V to 16 V, including standard 3.3 V logic rails. At 3.3 V, it maintains full functionality: output swing reaches ≥3.0 V (high) and ≤300 mV (low) with 4 mA load, and input common-mode range extends to 0 V to 1.8 V.
What is the input bias current specification for the TLC3702IPWRG4?
The TLC3702IPWRG4 exhibits an input bias current of 5 pA typical at 25°C and ≤0.6 nA maximum at 70°C, as confirmed in the electrical characteristics table of SLCS013E. This ultra-low bias enables accurate interfacing with high-impedance sources such as photodiodes, thermistors, and pH electrodes.
Is the TLC3702IPWRG4 pin-compatible with other TSSOP-8 comparators?
The TLC3702IPWRG4 uses standard TSSOP-8 pinout (1:OUT1, 2:IN1−, 3:IN1+, 4:GND, 5:VDD, 6:OUT2, 7:IN2−, 8:IN2+) and is functionally pin-compatible with TI's TLC3702CDR (SOIC-8) and TLC3702IDR (TSSOP-8). However, mechanical fit and thermal performance differ due to package-specific land patterns and thermal pad presence.
