Product details
Overview
TLC3702MDG4 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, ±8 mA output drive capability, and operation over −55°C to +125°C. It replaces LM339 in space- and power-constrained military and aerospace sensor interface circuits requiring single-supply operation from 4 V to 16 V.
For engineers reviewing the TLC3702MDG4 datasheet, TLC3702MDG4 pinout, TLC3702MDG4 application, or TLC3702MDG4 equivalent, this page delivers verified electrical specs, military-grade thermal performance, push-pull output behavior without external pullups, LinCMOS™ input stage advantages, and direct alternatives for high-reliability analog signal conditioning.
Technical Context
The TLC3702MDG4 integrates two independent comparators on a LinCMOS™ process, enabling rail-to-rail input common-mode range (0 V to VDD − 1.5 V) and stable input offset voltage across extreme temperatures. Its push-pull output stage eliminates external pullup resistors while delivering 2.7 μs typical propagation delay (tPLH) at 5-mV overdrive with 50-pF load.
Designed for military applications, the device features on-chip ESD protection rated to 2 kV HBM and 200 V CDM, plus absolute maximum ratings including ±18 V differential input voltage and −0.3 V to 18 V supply voltage. Input bias current remains below 30 nA at 125°C, supporting high-impedance sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - Enables direct integration into 5 V, 12 V, and 15 V military power rails without regulation. |
| Input Offset Voltage (max) | 10 mV over −55°C to +125°C - Ensures reliable threshold detection in wide-temperature sensor monitoring. |
| Propagation Delay (tPLH) | 2.7 μs typ at 5-mV overdrive, CL = 50 pF - Supports fast response in overvoltage/undervoltage fault detection. |
| Output Drive | ±8 mA - Directly drives logic inputs, LEDs, or small MOSFET gates without external buffers. |
| Quiescent Supply Current | 90 μA max over full temperature range - Enables multi-year battery life in remote telemetry nodes. |
| Input Bias Current | 30 nA max at 125°C - Maintains accuracy with high-value resistor dividers in precision reference circuits. |

|---|---|
|
Use Scenario: Detects when a 12 V power rail exceeds 12.5 V using a resistor divider and reference voltage. IC Role / Device Role / Timing Role: TLC3702MDG4 acts as a fast-response threshold detector with rail-compatible inputs and TTL/CMOS-compatible outputs. Use Value: Delivers 2.7 μs response time and ±8 mA drive to directly trigger a latch or shutdown FET without buffering. |
Use Scenario: Monitors thermistor voltage in an engine control unit across −40°C to +125°C ambient. IC Role / Device Role / Timing Role: TLC3702MDG4 compares conditioned thermistor output against fixed thresholds to generate fault flags. Use Value: Maintains ≤10 mV input offset and ≤30 nA input bias current at 125°C, ensuring consistent trip points over lifetime. |
| Window Comparator for Sensor Validation | Power Sequencing Controller |
|
Use Scenario: Validates that a pressure transducer output stays within 0.8 V–4.2 V bounds before enabling downstream logic. IC Role / Device Role / Timing Role: TLC3702MDG4 uses one comparator for upper limit and one for lower limit, with OR'd outputs. Use Value: Dual independent comparators in one SOIC-8 package reduce footprint vs discrete solutions; push-pull outputs simplify logic interfacing. |
Use Scenario: Controls startup order of multiple voltage rails (e.g., 1.8 V, 3.3 V, 5 V) in a radar subsystem. IC Role / Device Role / Timing Role: TLC3702MDG4 monitors each rail's presence and asserts enable signals only after valid thresholds are met. Use Value: 4 V minimum supply allows direct operation from earliest-rising rail; 90 μA max IDD minimizes sequencing circuit overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393AMX/NOPB | Open-drain output; requires external pullup; 2 mV offset max at 25°C but degrades to 7 mV at 125°C. | Lower cost for commercial systems; unsuitable where board space or pullup power loss matters. | Select LM393AMX/NOPB only if open-drain flexibility is needed and military temperature range is not required. |
| TLC3702CDR | Same core architecture but commercial grade (0°C to 70°C); 5 mV offset max; 18–40 μA IDD at 25°C. | Valid for non-military embedded systems with tighter budget and less extreme environmental demands. | Choose TLC3702CDR for cost-sensitive industrial controls where full military temp range is unnecessary. |
Compared with LM393AMX/NOPB, TLC3702MDG4 eliminates pullup components and sustains tighter offset stability at high temperature; compared with TLC3702CDR, it trades higher cost for guaranteed −55°C to +125°C operation and enhanced reliability screening.

FAQ
What is the maximum operating temperature for the TLC3702MDG4?
The TLC3702MDG4 is fully characterized and qualified for continuous operation from −55°C to +125°C, meeting military-grade thermal specifications per its M-grade designation. This rating is validated across all key parameters including input offset voltage (≤10 mV), supply current (≤90 μA), and output drive capability (±8 mA) at the extremes.
Does the TLC3702MDG4 require external pullup resistors on its outputs?
No, the TLC3702MDG4 features push-pull CMOS outputs that actively drive high and low states without external pullup resistors. This design reduces power dissipation, saves PCB area, and simplifies layout-unlike open-drain comparators such as the LM393AMX/NOPB which mandate external pullups to achieve logic-high levels.
What is the input common-mode voltage range of the TLC3702MDG4?
The TLC3702MDG4 supports a common-mode input voltage range of 0 V to VDD − 1.5 V across its full operating temperature range (−55°C to +125°C). At VDD = 5 V, this permits inputs from 0 V to 3.5 V; at VDD = 12 V, inputs may extend from 0 V to 10.5 V-enabling direct interface with most sensors and reference sources.
How does the TLC3702MDG4 compare to the LM339 in terms of power consumption?
The TLC3702MDG4 consumes approximately 1/20th the power of the LM339 while delivering comparable response times. At 5 V, TLC3702MDG4 draws just 18–40 μA (typ/max at 25°C), versus ~1.5 mA for the LM339. This micropower advantage enables battery-powered and thermally constrained deployments where LM339 would overheat or drain cells prematurely.
Is the TLC3702MDG4 pin-compatible with other variants in the TLC3702 family?
Yes, all TLC3702 variants-including TLC3702MDG4, TLC3702CDR, and TLC3702IDR-share identical SOIC-8 (DG) pinout and electrical interface. The only differences are temperature grading, screening, and minor parameter limits (e.g., offset voltage max and supply current max), making them drop-in replacements in compatible thermal environments.
