Product details
Overview
TLC339MDRG4 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 - enabling precision level detection in battery-powered sensor interfaces and industrial power supervisors.
For engineers reviewing the TLC339MDRG4 datasheet, TLC339MDRG4 pinout, TLC339MDRG4 application, or TLC339MDRG4 equivalent, key selection criteria include its −55°C to 125°C military-grade temperature range, 5 mV max input offset voltage at 25°C, open-drain output compatibility with wired-OR logic and mixed-voltage systems, and LinCMOS™ process stability under differential input stress.
Technical Context
The TLC339MDRG4 implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering CMOS-level power efficiency (80 µA max supply current) without sacrificing speed or input stability. Its architecture supports rail-to-rail common-mode input range (0 V to VDD−1.5 V) and exhibits 84 dB minimum common-mode rejection ratio across −55°C to 125°C.
Each comparator features an open-drain MOS output stage capable of sinking up to 20 mA per channel, with total ground current limited to 60 mA. Input bias current remains below 30 nA at 125°C, and input offset voltage drift is specified at ≤0.23 µV/month including first 30 days - critical for long-term monitoring circuits.

Applications
| Motor Speed Control | Supply Rail Monitoring |
|---|---|
Use Scenario: Pulse-width-modulated (PWM) motor driver uses comparator outputs to generate direction and enable signals based on potentiometer and sense voltage thresholds. IC Role / Device Role / Timing Role: Quad comparator provides independent hysteresis-based level detection for speed setpoint, direction logic, overcurrent flag, and thermal shutdown. Use Value: 2.5 µs response ensures timely fault cutoff during stall conditions; open-drain outputs interface directly with half-H bridge drivers (e.g., SN75603/4). | Use Scenario: Dual-rail supervisor monitors 5 V and 12 V supplies in embedded controllers, asserting reset or interrupt when either rail falls outside tolerance. IC Role / Device Role / Timing Role: Two comparators implement precise undervoltage lockout (UVLO) windows; remaining two generate early warning and clean reset pulses. Use Value: 5 mV max VIO enables ±25 mV detection accuracy on 5 V rail; −55°C to 125°C rating ensures reliability in unheated enclosures. |
| Nonoverlapping Clock Generation | Industrial Sensor Threshold Detection |
Use Scenario: Generates complementary, nonoverlapping clock phases for synchronous logic or gate drivers to prevent shoot-through in power converters. IC Role / Device Role / Timing Role: Three comparators form a ring oscillator with RC timing network; fourth comparator shapes output edges and enforces dead time. Use Value: LinCMOS™ input stability maintains consistent oscillation frequency across temperature; open-drain outputs allow level-shifted clock distribution. | Use Scenario: Detects threshold crossings from high-impedance sensors (e.g., RTDs, strain gauges) in programmable logic controllers and environmental monitors. IC Role / Device Role / Timing Role: Comparator acts as precision window detector or zero-crossing trigger; high input impedance avoids sensor loading errors. Use Value: 10¹² Ω input impedance preserves signal integrity from 100-kΩ+ sensor elements; 80 µA IDD enables continuous monitoring in energy-harvesting nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Bipolar process; 1.3 mA typical supply current; 300 ns faster propagation but 20× higher power; no guaranteed −55°C operation. | Not qualified for extended military temperature range; unsuitable for low-power or wide-temperature deployments. | Select LM339DR only for cost-sensitive commercial designs where power budget exceeds 1 mA and operating range is 0°C to 70°C. |
| TLC3704CDR | Push-pull outputs (no external pull-up required); 1.2 µs propagation; 100 µA supply current; same LinCMOS™ process and temp range. | Eliminates pull-up resistors but lacks wired-OR capability; incompatible with mixed-voltage bus architectures. | Choose TLC3704CDR when driving CMOS loads directly and board space is constrained; avoid where bus arbitration or level shifting is needed. |
Compared with LM339DR and TLC3704CDR, the TLC339MDRG4 uniquely balances ultra-low power (80 µA), military temperature qualification (−55°C to 125°C), and open-drain flexibility - making it optimal for ruggedized, battery-aware, and multi-rail industrial systems where both efficiency and interface versatility are mandatory.

FAQ
What is the maximum supply voltage for the TLC339MDRG4?
The TLC339MDRG4 supports a supply voltage range of 4 V to 16 V. Absolute maximum rating is 18 V, but operation above 16 V is not recommended or characterized. This range allows direct use with standard 5 V, 12 V, and unregulated industrial rails while maintaining full specification compliance across −55°C to 125°C.
Does the TLC339MDRG4 have push-pull or open-drain outputs?
The TLC339MDRG4 has open-drain CMOS outputs - not push-pull. Each of its four comparators can sink up to 20 mA but cannot source current. External pull-up resistors are required to establish logic-high levels, enabling wired-OR logic, mixed-voltage interfacing (e.g., 3.3 V MCU reading 12 V rail), and bus arbitration - functionality confirmed in the official TI datasheet SLCS119B.
What is the input offset voltage specification for the TLC339MDRG4?
The TLC339MDRG4 has a maximum input offset voltage (VIO) of 5 mV at 25°C, with worst-case drift bounded across temperature. At full military range (−55°C to 125°C), VIO is specified at 10 mV max. This value is measured under defined test conditions (VIC = VICRmin, VDD = 5 V to 10 V) and ensures reliable switching accuracy in precision threshold-detection circuits using the TLC339MDRG4.
Can the TLC339MDRG4 operate from a 3 V supply?
No, the TLC339MDRG4 is not rated for 3 V operation. Its minimum specified supply voltage is 4 V, as confirmed in the "Recommended Operating Conditions" table of SLCS119B. For 3 V–16 V operation, TI offers the TLC339C and TLC339I variants - but the TLC339MDRG4 (M-grade, D package) is strictly 4 V to 16 V, aligned with military-grade supply robustness requirements.
Is the TLC339MDRG4 RoHS compliant and lead-free?
Yes, the TLC339MDRG4 is RoHS compliant and features a lead-free NiPdAu (nickel-palladium-gold) lead finish, as documented in TI's Package Option Addendum (15-Jul-2026). It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for lead-free reflow with peak temperature of 260°C - fully compatible with modern Pb-free manufacturing processes.
