Product details
Overview
TLC339MDR from Texas Instruments is a quad differential voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 4 V to 16 V. It delivers 2.5 µs typical propagation delay at 5-mV overdrive, consumes only 200 µW typical supply power at 5 V, and features 10¹² Ω typical input impedance - enabling precision threshold detection in battery-powered sensor interfaces and industrial supervisory circuits.
For engineers reviewing the TLC339MDR datasheet, TLC339MDR pinout, TLC339MDR application, or TLC339MDR equivalent, key selection considerations include its military-grade −55°C to 125°C operating range, 5-mV max input offset voltage, open-drain output compatibility with wired-AND logic and mixed-voltage systems, and LinCMOS™ process stability under differential input stress.
Technical Context
The TLC339MDR implements four independent comparators using Texas Instruments' LinCMOS™ process, which combines high input impedance (10¹² Ω typ), ultra-low bias current (5 pA typ at 25°C), and exceptional input offset voltage stability (0.23 µV/month drift including first 30 days). Its open-drain output stage requires external pull-up resistors and supports interfacing across voltage domains.
It operates without dual supplies - common-mode input range extends to VDD−1.5 V over full temperature range, and absolute maximum ratings permit −0.3 V to 18 V supply voltage and ±18 V differential input voltage. Propagation delay is specified down to 2 mV overdrive, with tPLH/tPHL of 2.5 µs/2.1 µs typ at 5-mV overdrive and 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - enables direct use with 5 V, 12 V, or unregulated industrial rails without LDO pre-regulation. |
| Propagation Delay (tPLH/tPHL) | 2.5 µs / 2.1 µs typ at 5-mV overdrive - supports fast response in overvoltage lockout and PWM timing circuits. |
| Input Offset Voltage (VIO) | ≤5 mV max at −55°C to 125°C - ensures reliable switching thresholds across military temperature extremes. |
| Supply Current (IDD) | 44–80 µA typ (four comparators, outputs low) - enables multi-year operation on coin-cell batteries in remote monitoring nodes. |
| Input Impedance | 10¹² Ω typ - minimizes loading on high-impedance sources like thermistors, photodiodes, or RC timing networks. |
| Output Type | Open-drain CMOS - allows wired-AND configuration, level translation via external pull-up, and direct interface to microcontroller interrupt pins. |
| ESD Protection | On-chip ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) - reduces need for external TVS diodes in board-level ESD hardening. |

Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ Process Technology | Delivers 10¹² Ω input impedance and sub-pA bias current while maintaining stable offset voltage under differential stress - critical for high-gain sensor front-ends. |
| Military Temperature Rating | Specified from −55°C to +125°C - qualified for aerospace, defense, and downhole industrial applications where commercial or industrial grades fail. |
| Ultra-Low Power Consumption | 200 µW typical at 5 V - enables always-on monitoring in energy-harvesting or long-life battery systems without duty cycling. |
| Open-Drain Output Architecture | Supports flexible pull-up to any voltage ≤18 V - simplifies interface to 3.3 V microcontrollers, 5 V logic, or 12 V PLC inputs without level shifters. |
| Input Common-Mode Range | Extends to VDD−1.5 V across full temperature range - permits direct sensing of signals near VDD (e.g., rail-to-rail battery voltage monitoring). |
Applications
| Battery Voltage Supervisor | Motor Overcurrent Detection |
|---|---|
Use Scenario: Monitoring Li-ion battery pack voltage during charge/discharge cycles to trigger cutoff or alert before under-voltage or over-voltage conditions. IC Role / Device Role / Timing Role: Quad comparator provides independent high/low threshold detection per cell or pack segment, with open-drain outputs feeding OR-wired interrupt lines. Use Value: 5-mV max VIO ensures accurate trip points across −55°C to 125°C; 200 µW quiescent power extends battery life in portable diagnostic tools. | Use Scenario: Sensing shunt resistor voltage in H-bridge motor drivers to disable PWM when current exceeds safe limit. IC Role / Device Role / Timing Role: One comparator channel compares amplified shunt voltage against reference; fast 2.5 µs response prevents MOSFET destruction during fault events. Use Value: Open-drain output directly drives gate driver enable/disable pin; wide 4–16 V supply range matches motor rail voltages without auxiliary supply. |
| Two-Phase Clock Generator | Enhanced Power Supply Supervisor |
Use Scenario: Generating non-overlapping clock phases for synchronous logic or switched-capacitor circuits using RC oscillator feedback. IC Role / Device Role / Timing Role: Two comparators form hysteresis oscillator; third and fourth provide phase alignment and dead-time control via cross-coupled feedback. Use Value: LinCMOS™ input stability prevents frequency drift with temperature; 10¹² Ω input avoids loading timing capacitors. | Use Scenario: Monitoring multiple DC rails (e.g., 3.3 V, 5 V, 12 V) in telecom equipment to assert system reset or interrupt on brownout/fail conditions. IC Role / Device Role / Timing Role: Each comparator monitors one rail against precision reference; open-drain outputs wire-AND into single reset line with pull-up to highest rail. Use Value: −55°C to 125°C rating ensures reliability in sealed outdoor enclosures; 5-mV VIO enables tight tolerance supervision (±1% at 5 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher supply current (500 µA typ), slower response (1.3 µs min but 30 µs typical at low overdrive), bipolar input stage (nA bias current vs pA), no military temp grade. | Not suitable for battery-powered or high-precision low-drift applications; limited to commercial/industrial ambient ranges. | Select LM339DR only for cost-sensitive, non-military designs where speed and power are secondary. |
| TLC3704CDR | Push-pull (not open-drain) outputs, identical LinCMOS™ specs otherwise; requires no external pull-up; higher output drive strength (20 mA sink/source). | Incompatible with wired-AND or level-shifting topologies; better suited for driving LEDs or logic inputs directly. | Choose TLC3704CDR when direct logic-level output is needed and pull-up resistors are undesirable. |
Compared with LM339DR and TLC3704CDR, the TLC339MDR uniquely balances ultra-low power (200 µW), military temperature capability, and open-drain flexibility - making it irreplaceable in harsh-environment, energy-constrained comparator applications requiring long-term offset stability.

FAQ
What is the operating temperature range for the TLC339MDR?
The TLC339MDR is characterized for operation from −55°C to +125°C, meeting military-grade environmental requirements. This full-range specification is confirmed in the "recommended operating conditions" table of the official datasheet (SLCS119B, Rev. December 2006), and applies specifically to the M-grade devices including TLC339MDR. The device maintains 5-mV max input offset voltage and stable propagation delay across this entire span.
Does the TLC339MDR require dual power supplies?
No, the TLC339MDR operates from a single supply ranging from 4 V to 16 V. Its input common-mode range extends from ground to VDD−1.5 V, and its open-drain outputs interface cleanly with pull-up resistors to any compatible voltage rail. This single-supply architecture eliminates the need for negative supplies in applications such as battery voltage monitoring or industrial sensor interfaces - a key advantage over legacy bipolar comparators.
What is the maximum input differential voltage the TLC339MDR can tolerate?
The TLC339MDR supports a maximum differential input voltage (VID) of ±18 V, as stated in the Absolute Maximum Ratings table. This rating holds regardless of supply voltage and enables robust operation in noisy industrial environments where transient spikes may appear across comparator inputs - for example, when monitoring motor phase currents or relay coil back-EMF without additional clamping circuitry.
Can the TLC339MDR outputs drive an LED directly?
No - the TLC339MDR features open-drain CMOS outputs that can only sink current (up to 20 mA per output). To drive an LED, an external pull-up resistor to a positive supply and series current-limiting resistor are required, with the LED cathode connected to the output pin and anode to VDD. Direct anode-to-output connection would not function, as the device cannot source current from its output terminals.
Is the TLC339MDR pin-compatible with the LM339?
Yes, the TLC339MDR uses the standard 14-pin SOIC (D) package with identical pinout to the LM339 - including GND (pin 8), VDD (pin 14), and matched input/output assignments for all four comparators. However, due to its LinCMOS™ process, it offers significantly lower power (200 µW vs ~500 µW), higher input impedance (10¹² Ω vs ~1 MΩ), and superior offset stability - making it a functional upgrade, not just a drop-in replacement.
