Product details
Overview
TLC339IDR 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 200 µW typical supply power at 5 V, 2.5 µs typical propagation delay with 5-mV overdrive, and 10¹² Ω typical input impedance - enabling precision level detection in battery-powered industrial sensors and power-supply supervisors.
For engineers reviewing the TLC339IDR datasheet, TLC339IDR pinout, TLC339IDR application, or TLC339IDR equivalent, key selection criteria include its industrial temperature range (−40°C to 85°C), low input bias current (≤30 nA at 85°C), open-drain output compatibility with wired-AND logic, and LinCMOS® process stability under differential input stress.
Technical Context
The TLC339IDR implements four independent comparators using Texas Instruments' LinCMOS® process, delivering high input impedance and stable offset voltage (≤7 mV max over −40°C to 85°C) without sacrificing speed. Its open-drain output stage requires external pull-up resistors and supports interfacing to mixed-voltage systems and wired-logic configurations.
Unlike bipolar comparators, the LinCMOS® architecture eliminates input phase reversal under common-mode stress and maintains CMRR ≥84 dB and kSVR ≥84 dB across its full operating temperature range - critical for reliable threshold detection in noisy industrial environments.
Key Specifications

Applications
| Motor Speed Control | Power Supply Supervision |
|---|---|
Use Scenario: Pulse-width-modulated (PWM) control of DC brush motors using potentiometer-set reference and feedback voltage. IC Role / Device Role / Timing Role: TLC339IDR compares feedback voltage against reference to generate PWM enable signal; open-drain outputs interface directly to half-H driver enable pins. Use Value: Low input bias current avoids loading of high-resistance potentiometer; 2.5 µs response enables >100 kHz PWM loop bandwidth. | Use Scenario: Monitoring 5 V and 12 V rails for undervoltage lockout and early power-fail warning in microprocessor-based systems. IC Role / Device Role / Timing Role: TLC339IDR acts as dual-rail supervisor with separate thresholds; one comparator triggers reset, another asserts interrupt before brownout. Use Value: 7 mV max offset ensures accurate trip points; wide supply range (3–16 V) supports direct sensing without regulators. |
| Nonoverlapping Clock Generation | Industrial Sensor Threshold Detection |
Use Scenario: Generating two-phase, nonoverlapping clock signals for synchronous logic or gate drivers in motor drives. IC Role / Device Role / Timing Role: TLC339IDR implements oscillator and phase-splitting logic using RC timing networks and cross-coupled comparators. Use Value: Open-drain outputs allow shared pull-up for logic-level compatibility; low propagation delay variation (<100 ns) ensures tight dead-time control. | Use Scenario: Detecting temperature thresholds from NTC thermistors or light levels from photodiodes in factory automation sensors. IC Role / Device Role / Timing Role: TLC339IDR serves as precision window comparator or zero-crossing detector; high input impedance prevents sensor loading. Use Value: 10¹² Ω input impedance preserves accuracy of high-resistance sensors; industrial temp range ensures reliability in harsh enclosures. |
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; higher supply current (500 µA typ); wider offset voltage (±2 mV min, ±36 mV max); no guaranteed operation below 2 V. | Less suitable for battery-powered systems; lower input impedance (250 kΩ) loads high-Z sensors. | Select LM339DR only where cost is primary and power/precision constraints are relaxed. |
| TLC3704CDR | Push-pull output (no external pull-up needed); higher supply current (120 µA typ); same LinCMOS® input performance. | Preferred where drive strength or simplified layout outweighs need for wired-AND capability. | Choose TLC3704CDR when replacing open-drain logic is acceptable and board space is constrained. |
Compared with LM339DR and TLC3704CDR, the TLC339IDR uniquely balances ultra-low power (44 µA), high input impedance (10¹² Ω), and open-drain flexibility - making it optimal for precision, low-power industrial monitoring where wired logic or mixed-voltage interfacing is required.

FAQ
What is the maximum operating temperature range for the TLC339IDR?
The TLC339IDR is characterized for operation from −40°C to +85°C, meeting industrial temperature requirements. This range is confirmed in the "recommended operating conditions" section of the official datasheet (SLCS119B, Rev. December 2006), and applies specifically to the TLC339I grade - which the TLC339IDR implements in SOIC-14 packaging.
Does the TLC339IDR require external pull-up resistors on its outputs?
Yes, the TLC339IDR features open-drain CMOS outputs and requires external pull-up resistors on pins 1, 2, 4, and 5 (OUT1–OUT4). The value depends on load and speed requirements; typical values range from 2.2 kΩ to 10 kΩ pulled to VDD or another logic rail. This architecture enables wired-AND logic and mixed-voltage interfacing - a core functional feature of the TLC339IDR.
Can the TLC339IDR operate from a 3.3 V supply?
Yes, the TLC339IDR supports supply voltages from 3 V to 16 V, including standard 3.3 V rails. Its input common-mode range extends down to 0 V and up to VDD−1.5 V, so at 3.3 V it accepts inputs from 0 V to 1.8 V - sufficient for many low-voltage sensor interfaces. Electrical characteristics such as propagation delay and supply current are specified down to 3 V in the TLC339I data tables.
What is the input offset voltage specification for the TLC339IDR?
The TLC339IDR has a maximum input offset voltage of 7 mV over its full operating temperature range of −40°C to +85°C. At 25°C, typical offset is 1.4 mV, with a maximum of 5 mV. These values are explicitly defined in the "electrical characteristics" table for the TLC339I grade in the SLCS119B datasheet and apply directly to the TLC339IDR device.
Is the TLC339IDR pin-compatible with the LM339?
No, the TLC339IDR is not pin-compatible with the LM339. While both are quad comparators in SOIC-14 packages, their pinouts differ: the LM339 uses pins 1, 2, 4, 5 for outputs and pins 3, 6, 12, 13 for inverting inputs, whereas the TLC339IDR assigns outputs to pins 1, 2, 4, 5 and inverting inputs to pins 3, 6, 12, 13 - matching the LM339 layout. However, the TLC339IDR datasheet confirms identical pin assignment (D package top view), making it a functional and pin-for-pin replacement for LM339 in most designs - though electrical differences (e.g., input bias, power) must be verified.
