Product details
Overview
TLC3702ID from Texas Instruments is a dual micropower LinCMOS™ voltage comparator designed for single-supply operation across industrial temperature ranges (−40°C to 85°C). It delivers 100 μW typical supply power at 5 V, 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive, and ±8 mA push-pull CMOS output drive-enabling direct capacitive load driving without external pullup resistors in battery-powered sensor threshold detection circuits.
For engineers reviewing the TLC3702ID datasheet, TLC3702ID pinout, TLC3702ID application, or TLC3702ID equivalent, key selection considerations include its micropower consumption, rail-to-rail input capability (0 V to VDD − 1.5 V), TTL/CMOS-compatible push-pull outputs, and guaranteed performance across −40°C to 85°C without derating.
Technical Context
The TLC3702ID implements two independent comparators using Texas Instruments' LinCMOS™ process, delivering high input impedance (>10¹² Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage (≤7 mV over full temperature range). Its differential input stage supports common-mode voltages from −0.2 V to VDD − 1.5 V.
The push-pull output stage eliminates reliance on external pullup resistors, enabling fast switching (tPHL = 2.3 μs typ) into 50-pF loads while maintaining compatibility with both CMOS and TTL logic families-critical for low-power level-shifting and window-comparator topologies in embedded control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - supports wide-input industrial rails and battery-backed operation without regulation. |
| Quiescent Supply Current | 18–65 μA (both comparators, −40°C to 85°C) - enables multi-year operation from coin cells in remote monitoring nodes. |
| Input Offset Voltage | ≤7 mV (max, −40°C to 85°C) - ensures reliable threshold detection accuracy in precision analog sensing. |
| Propagation Delay | tPLH = 2.7 μs / tPHL = 2.3 μs (5-mV overdrive, CL = 50 pF) - balances speed and power for real-time comparator response. |
| Output Drive Capability | ±20 mA per output - directly drives LEDs, small relays, or logic inputs without buffering. |
| Input Common-Mode Range | −0.2 V to VDD − 1.5 V - allows ground-referenced or rail-sensing configurations without clamping diodes. |
| ESD Protection | 2000 V HBM, 200 V CDM - meets industrial handling requirements without external protection components. |

Applications
| Overvoltage Protection Circuit | Battery Charge State Monitor |
|---|---|
|
Use Scenario: Detects when input voltage exceeds safe threshold in DC power supplies or solar charge controllers. IC Role / Device Role / Timing Role: Dual comparator configures as window detector: one compares against upper limit, the other against lower limit. Use Value: Eliminates need for external op-amps or voltage references; operates from same rail as protected system (3–16 V). |
Use Scenario: Monitors cell voltage during Li-ion charging to trigger cutoff at 4.2 V and pre-charge enable below 3.0 V. IC Role / Device Role / Timing Role: Comparator 1 detects full-charge threshold; comparator 2 enables trickle-charge mode at low voltage. Use Value: Micropower operation (<65 μA total) preserves battery capacity during long idle periods between charge cycles. |
| Industrial Sensor Interface | Low-Power Wake-Up Detector |
|
Use Scenario: Converts analog output from RTD, thermistor, or pressure transducer into digital alert signal for microcontroller. IC Role / Device Role / Timing Role: Single comparator compares conditioned sensor voltage against programmable reference; second comparator unused or configured for hysteresis. Use Value: Input common-mode range includes ground, enabling direct connection to grounded-sensor bridges without level-shifting. |
Use Scenario: Wakes sleeping MCU when external event (e.g., door open, motion trigger) exceeds preset analog threshold. IC Role / Device Role / Timing Role: One comparator monitors external signal; output drives MCU interrupt pin; second comparator reserved for secondary wake condition. Use Value: 100 μW typical power enables always-on monitoring with sub-μA average system current in duty-cycled designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-collector output; requires external pullup; higher quiescent current (200 μA typ); wider offset (7 mV max, but not specified over full temp range). | Not suitable for direct capacitive load driving or rail-to-rail input near GND without external biasing. | Select LM393DR only if open-collector interface is required or cost is primary constraint; verify pullup resistor sizing for target speed. |
| TLV3702IDR | Lower supply current (8 μA typ), rail-to-rail input/output, but narrower supply range (2.7–16 V) and reduced output drive (±2 mA). | Better for ultra-low-power systems with tight voltage margins; insufficient for driving LEDs or logic with >2 mA load. | Choose TLV3702IDR when minimizing sleep current is critical and output loading is light; confirm VDD stability within 2.7–16 V window. |
Compared with LM393DR and TLV3702IDR, the TLC3702ID uniquely combines micropower operation, push-pull drive, full industrial temperature rating, and robust ESD protection-making it optimal for space-constrained, battery-operated industrial sensors requiring reliable threshold detection without design compromises.

FAQ
What is the maximum operating temperature range for the TLC3702ID?
The TLC3702ID is characterized for continuous operation from −40°C to +85°C. This industrial-grade temperature rating is verified per TI's qualification standards and applies across all electrical parameters in the datasheet, including input offset voltage (≤7 mV), supply current (≤65 μA), and propagation delay (tPHL ≤ 3.5 μs). The device remains fully functional within this range without derating.
Does the TLC3702ID require an external pullup resistor on its outputs?
No, the TLC3702ID does not require an external pullup resistor. Its push-pull CMOS output stage actively drives both high and low states, delivering ±8 mA typical output current. This architecture enables direct interfacing with CMOS and TTL logic, LEDs, and small relays-eliminating board space, BOM cost, and timing uncertainty associated with pullup resistors.
Can the TLC3702ID operate from a 3-V supply?
Yes, the TLC3702ID supports a minimum supply voltage of 3 V, with full functionality across its specified industrial temperature range. At 3 V, it maintains 18–65 μA supply current, ≤7 mV input offset voltage, and usable propagation delay (tPLH ≈ 4.5 μs typ with 5-mV overdrive). Input common-mode range extends down to −0.2 V, enabling ground-referenced sensing.
How does the TLC3702ID compare to the LM339 in terms of power consumption?
The TLC3702ID consumes approximately one-twentieth the power of the LM339 while delivering comparable response times. At 5 V, TLC3702ID draws 18–65 μA (both comparators), versus ~1.5 mA for the LM339. This 20× reduction enables battery-powered applications with multi-year runtime, whereas LM339-based designs typically require frequent replacement or recharging.
Is the TLC3702ID pin-compatible with other variants in the TLC3702 family?
Yes, the TLC3702ID shares identical SOIC-8 (D) pinout with TLC3702CD, TLC3702CP, TLC3702MD, TLC3702MFK, and TLC3702MJG. All variants use the same 1–8 pin assignment: 1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+. Temperature grade and packaging differences do not affect pin compatibility or PCB layout.
