Product details
Overview
TLC3702IDG4 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, 100 μW typical supply power at 5 V, and 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive - used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLC3702IDG4 datasheet, TLC3702IDG4 pinout, TLC3702IDG4 application, or TLC3702IDG4 equivalent, this page delivers verified specifications, industrial-temperature-grade performance data (−40°C to 85°C), package mapping to SOIC-8, and real-world design context for low-power analog signal conditioning.
Technical Context
The TLC3702IDG4 implements two independent comparators on a LinCMOS™ process, enabling single-supply operation from 3 V to 16 V while maintaining ultra-low input bias current (5 pA typ at 25°C) and stable input offset voltage across temperature (7 mV max over −40°C to 85°C). Its push-pull output stage drives capacitive loads directly without external pullup resistors, eliminating associated power loss and board space.
This architecture supports TTL-compatible logic levels and delivers ±20 mA output drive capability, with common-mode input range extending to VDD − 1.5 V across the full industrial temperature range. On-chip ESD protection meets 2-kV HBM and 200-V CDM standards.

Applications
| Motor Overcurrent Detection | Battery Voltage Monitor |
|---|---|
Use Scenario: Detecting current-sense amplifier output crossing preset thresholds during motor stall or short-circuit events. IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel triggers low-voltage fault, the other high-current fault. Use Value: 2.3 μs response time ensures rapid shutdown before thermal damage; 65 μA quiescent current minimizes impact on control MCU power budget. |
Use Scenario: Monitoring lithium-ion cell voltage during charge/discharge cycles to enable low-battery warning and overvoltage cutoff. IC Role / Device Role / Timing Role: Precision voltage comparator comparing cell voltage against internal reference - operates directly from battery rail. Use Value: 7 mV max input offset ensures accurate 3.0 V and 4.2 V trip points; 3 V min supply allows operation down to deeply discharged cells. |
| Programmable Logic Level Shifter | Smoke Detector Signal Thresholding |
Use Scenario: Converting analog sensor outputs (e.g., thermistor, photodiode) into clean digital logic levels for microcontroller GPIO inputs. IC Role / Device Role / Timing Role: Single comparator acting as rail-to-rail input buffer - driven by adjustable reference voltage (e.g., DAC or potentiometer). Use Value: Rail-compatible input range (0 V to VDD − 1.5 V) accepts full-scale sensor signals; push-pull output guarantees TTL/CMOS logic compatibility. |
Use Scenario: Comparing ionization chamber current against calibrated thresholds to distinguish smoke presence from ambient noise. IC Role / Device Role / Timing Role: Ultra-low-input-current comparator detecting sub-nA currents - biased with high-value feedback resistor. Use Value: 5 pA input bias current prevents signal corruption in high-impedance sensing paths; 100 μW power enables continuous operation in battery-only detectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 μA typ), open-collector output requiring external pullup, 2 mV higher offset (9 mV max over −40°C to 85°C). | Requires additional resistor and consumes ~5× more power - suitable only where cost is primary constraint and board space is not limited. | Select LM393DR only when legacy compatibility or lowest unit cost outweighs power and layout efficiency. |
| TLV3702IDR | Lower supply current (35 μA max), rail-to-rail input, but reduced output drive (±8 mA) and narrower supply range (2.7–16 V). | Better for ultra-low-power IoT nodes with rail-to-rail sensor signals; insufficient for driving 20 mA loads like relays or LEDs directly. | Choose TLV3702IDR when input signal spans full supply range and load current ≤8 mA; retain TLC3702IDG4 for higher drive or industrial temp margin. |
Compared with LM393DR and TLV3702IDR, the TLC3702IDG4 uniquely balances industrial temperature operation, 20 mA output drive, and micropower consumption - making it optimal for battery-powered industrial sensors requiring robust output interfacing without external components.

FAQ
What is the operating temperature range for the TLC3702IDG4?
The TLC3702IDG4 is characterized for operation from −40°C to +85°C, meeting industrial-grade environmental requirements. This range is validated across all key parameters including input offset voltage (7 mV max), supply current (65 μA max), and propagation delay - ensuring consistent performance in factory automation, outdoor equipment, and automotive under-hood applications where the TLC3702IDG4 is deployed.
Does the TLC3702IDG4 require an external pullup resistor on its outputs?
No, the TLC3702IDG4 features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pullup resistors. This design reduces system power consumption by over 100 μW per channel and saves PCB area - a key differentiator versus open-collector comparators like the LM393. The TLC3702IDG4 delivers TTL-compatible logic levels directly from its OUT A and OUT B pins.
What is the maximum input voltage range relative to supply for the TLC3702IDG4?
The TLC3702IDG4 supports a common-mode input voltage range of 0 V to VDD − 1.5 V across its full industrial temperature range. For example, at VDD = 5 V, inputs may swing from 0 V to 3.5 V; at VDD = 12 V, the upper limit extends to 10.5 V. This rail-aware input structure enables direct interfacing with sensors and dividers without level-shifting - a core capability leveraged in the TLC3702IDG4's target applications.
How does the TLC3702IDG4 compare to the TLC3702CD in terms of performance?
The TLC3702IDG4 shares identical electrical specifications with the TLC3702CD except for temperature grading: the "I" grade is rated for −40°C to +85°C, while the "C" grade is limited to 0°C to +70°C. Both use the same SOIC-8 (D) package and deliver 7 mV max input offset, 2.3 μs tPLH, and 65 μA max supply current - but only the TLC3702IDG4 is qualified for extended industrial environments where the TLC3702IDG4 must operate reliably.
Is the TLC3702IDG4 pin-compatible with other dual comparators in SOIC-8 packages?
Yes, the TLC3702IDG4 uses the industry-standard SOIC-8 pinout defined for dual comparators (pins 1–4 for Channel A, 5 = VDD, 6–8 for Channel B), matching LM393, TLV3702, and MAX9022. However, functional compatibility requires verification of output type (push-pull vs. open-collector) and supply range - the TLC3702IDG4's push-pull outputs and 3–16 V range differ from many alternatives, so direct substitution requires circuit review.
