Product details
Overview
TLC339CDBR from Texas Instruments is a quad differential voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 3 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 level detection in battery-powered sensor interfaces.
For engineers reviewing the TLC339CDBR datasheet, TLC339CDBR pinout, TLC339CDBR application, or TLC339CDBR equivalent, key selection criteria include its commercial-temperature-range rating (0°C to 70°C), SOIC-14 package, low-input-bias-current LinCMOS™ architecture, and compatibility with wired-AND logic and pull-up-based output interfacing.
Technical Context
The TLC339CDBR implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering high input impedance and stable offset voltage (≤6.5 mV max over 0°C–70°C) without sacrificing speed. Its open-drain output stage requires external pull-up resistors and supports mixed-voltage interfacing across logic families.
It operates with common-mode input range extending to VDD−1.5 V and exhibits 84 dB minimum common-mode rejection ratio (CMRR) and 85 dB supply-voltage rejection ratio (kSVR) at 25°C - critical for noise-immune threshold detection in industrial control and power monitoring circuits.
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 waveform against adjustable thresholds to generate non-overlapping drive signals for half-H bridge drivers. Use Value: Enables precise, jitter-free motor commutation with <2.5 µs response - critical for smooth low-RPM operation and torque consistency. | Use Scenario: Monitoring 5 V and 12 V rails for undervoltage lockout and early power-fail warning in microcontroller-based systems. IC Role / Device Role / Timing Role: Two comparators detect rail collapse below preset thresholds; third generates reset pulse, fourth triggers interrupt flag. Use Value: Provides deterministic, low-latency fault response (<5 µs) with no external hysteresis components required due to inherent LinCMOS™ stability. |
| Two-Phase Clock Generation | Sensor Threshold Detection |
Use Scenario: Generating complementary, non-overlapping clock phases for synchronous digital logic or switched-capacitor circuits. IC Role / Device Role / Timing Role: Three comparators configured as oscillators and phase shifters produce two precisely timed, dead-time-controlled output pairs. Use Value: Achieves sub-microsecond phase alignment and programmable dead time via RC network - avoids shoot-through in power converters. | Use Scenario: Converting analog sensor outputs (e.g., thermistor, photodiode, pressure transducer) into clean digital logic levels. IC Role / Device Role / Timing Role: Comparator acts as precision voltage-level translator with user-defined hysteresis via feedback resistor. Use Value: Supports high-impedance sensor interfaces with <1 pA bias current - prevents measurement error in µA-level leakage-sensitive applications. |
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 at 15-mV overdrive), bipolar input stage (nA-level bias current). | Less suitable for battery-powered systems; requires larger pull-up resistors due to lower output drive strength. | Select LM339DR only when cost is primary constraint and power/precision trade-offs are acceptable. |
| TLC3704CDR | Push-pull output (no external pull-up needed), higher supply current (120 µA typ), same LinCMOS™ input performance. | Eliminates external pull-up resistors but lacks wired-AND capability; not drop-in compatible due to different output architecture. | Choose TLC3704CDR when simplified board layout and guaranteed logic-high output are prioritized over bus-sharing flexibility. |
Compared with LM339DR and TLC3704CDR, the TLC339CDBR uniquely balances ultra-low power (200 µW), precision (6.5 mV VIO max), and open-drain versatility - making it optimal for space-constrained, multi-rail, and battery-backed applications where design longevity and signal fidelity are critical.

FAQ
What is the operating temperature range for the TLC339CDBR?
The TLC339CDBR is specified for the commercial temperature range of 0°C to 70°C. This rating is confirmed in the "recommended operating conditions" table for the TLC339C variant in the official TI datasheet SLCS119B. Operation outside this range may result in parametric degradation or functional failure.
Does the TLC339CDBR require external pull-up resistors on its outputs?
Yes, the TLC339CDBR features open-drain CMOS outputs and requires external pull-up resistors to establish defined logic-high states. The datasheet specifies that each output can sink up to 20 mA, and the total current to ground must not exceed 60 mA - so pull-up values must be selected accordingly to meet load and speed requirements.
Can the TLC339CDBR operate from a 3.3 V supply?
Yes, the TLC339CDBR supports supply voltages from 3 V to 16 V, making it fully compatible with standard 3.3 V logic systems. At 3.3 V, its common-mode input range extends from −0.2 V to 1.8 V (VDD−1.5 V), and propagation delay increases slightly versus 5 V operation - verified in Figure 14 of the datasheet.
What is the maximum input voltage allowed at the IN+ and IN− pins of the TLC339CDBR?
The absolute maximum input voltage for both IN+ and IN− pins is −0.3 V to VDD, as stated in the Absolute Maximum Ratings table. Exceeding this range risks forward-biasing internal ESD diodes; however, damage is avoided if input current remains below ±5 mA, per TI application guidance.
How does the LinCMOS™ process benefit the TLC339CDBR compared to standard CMOS comparators?
The LinCMOS™ process used in the TLC339CDBR provides extremely stable input offset voltage (≤0.23 µV/month drift), ultra-low input bias current (<1 pA at 25°C), and high input impedance (10¹² Ω typ) - all while maintaining low power and fast response. These traits enable precision, long-term reliability in sensor and monitoring circuits where standard CMOS comparators exhibit greater drift and leakage.
