Product details
Overview
TLC339MN 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 with 5-mV overdrive, consumes only 200 µW typical at 5 V, and features 10¹² Ω typical input impedance. It is used in precision threshold detection circuits within industrial power supervisors and motor control feedback loops.
For engineers reviewing the TLC339MN datasheet, TLC339MN pinout, TLC339MN application, or TLC339MN equivalent, key selection criteria include its military-grade −55°C to 125°C operating range, 5 mV max input offset voltage at 25°C, open-drain output compatibility with wired-OR logic, and LinCMOS™ process stability under differential input stress.
Technical Context
The TLC339MN implements four independent comparators using Texas Instruments' LinCMOS™ process, enabling high input impedance (10¹² Ω typ) and ultra-low bias currents (5 pA typ at 25°C) while maintaining stable input offset voltage (≤5 mV at 25°C, ≤10 mV across full temperature range). Its open-drain output stage requires external pull-up and supports interfacing to mixed-voltage systems.
It operates without dual supplies-common-mode input range extends from 0 V to VDD−1.5 V across −55°C to 125°C-and achieves 84 dB common-mode rejection ratio and 85 dB supply-voltage rejection ratio at 25°C, ensuring robust performance in noisy industrial environments.
Key Specifications

Applications
| Motor Speed Control | Power Supply Supervision |
|---|---|
Use Scenario: Pulse-width-modulated (PWM) control of DC motor speed using potentiometer-adjusted reference and sensed back-EMF feedback. IC Role / Device Role / Timing Role: Quad comparator compares ramp signal against reference and feedback to generate non-overlapping drive pulses for half-H bridge drivers. Use Value: Enables precise, jitter-free PWM generation with <2.5 µs response, supporting closed-loop speed regulation at kHz switching frequencies. | Use Scenario: Monitoring 5 V and 12 V rails in industrial PLCs to trigger early power-fail warning and hard reset before brownout. IC Role / Device Role / Timing Role: Two comparators detect undervoltage thresholds; third generates time-delayed reset via RC network; fourth provides interrupt flag. Use Value: Achieves reliable rail supervision across −55°C to 125°C with <5 mV offset error, eliminating false resets in wide-temperature deployments. |
| Two-Phase Clock Generation | Threshold-Based Sensor Interface |
Use Scenario: Generating complementary, non-overlapping clock signals for synchronous logic or gate drivers in motor controllers. IC Role / Device Role / Timing Role: Three comparators form oscillator core with RC timing; fourth shapes dead-time between phases. Use Value: Provides deterministic phase separation with <10 ns transition time, preventing shoot-through in power stages. | Use Scenario: Converting analog outputs from temperature or pressure sensors into clean digital logic levels for microcontroller input. IC Role / Device Role / Timing Role: Comparator acts as precision zero-crossing or window detector with hysteresis added externally. Use Value: Leverages 10¹² Ω input impedance to avoid sensor loading, preserving accuracy of high-Z sources like RTDs or piezoelectric elements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339N | Higher quiescent current (500 µA vs. 80 µA), slower response (1.3 µs min but typically >3 µs), bipolar process, no ESD protection. | Not suitable for low-power or high-reliability military/industrial environments; lacks LinCMOS™ stability. | Select TLC339MN where power budget <100 µA or operating temperature exceeds 85°C is required. |
| TLC3704CN | Push-pull (not open-drain) outputs, higher supply current (120 µA), same LinCMOS™ process and temperature range. | Eliminates need for external pull-ups but cannot perform wired-OR logic or level translation. | Choose TLC339MN when interfacing to multiple logic families or implementing priority interrupt arbitration. |
Compared with LM339N and TLC3704CN, the TLC339MN uniquely combines military-temperature operation, ultra-low power, open-drain flexibility, and LinCMOS™ input stability-making it optimal for ruggedized embedded systems requiring long-term parametric reliability.

FAQ
What is the maximum operating temperature range for the TLC339MN?
The TLC339MN is characterized for operation from −55°C to 125°C, meeting military-grade temperature specifications. This full-range qualification is confirmed in the "AVAILABLE OPTIONS" table and "recommended operating conditions" section of the official datasheet, where TLC339MN is explicitly listed under the −55°C to 125°C row alongside the J and FK packages.
Does the TLC339MN require dual power supplies?
No, the TLC339MN operates from a single supply ranging from 4 V to 16 V. Its common-mode input voltage range extends from 0 V to VDD−1.5 V across the full −55°C to 125°C temperature range, and its open-drain outputs interface directly to pull-up networks-eliminating any need for negative or split supplies.
What is the input offset voltage specification for the TLC339MN?
The TLC339MN has a maximum input offset voltage of 5 mV at 25°C and 10 mV across the full −55°C to 125°C operating range. These values are specified in the "electrical characteristics" tables for TLC339M devices and verified in the "AVAILABLE OPTIONS" matrix where TLC339MN is assigned the 5 mV VIO max column.
Can the TLC339MN outputs drive an LED directly?
Yes-the TLC339MN outputs are open-drain CMOS and can sink up to 20 mA each. To drive an LED, connect the anode to a positive supply (≤16 V) and the cathode to an output pin, with a series current-limiting resistor. Ensure total sink current across all four outputs remains ≤60 mA to stay within absolute maximum ratings.
Is the TLC339MN RoHS compliant?
Yes, the TLC339MN (PDIP-N package) is RoHS compliant, as confirmed in TI's official Package Option Addendum: material type is "Production", RoHS column states "Yes", and lead finish is "NIPDAU". The part marking "TLC339MN" appears in the active, RoHS-compliant entries for PDIP packaging.
