Product details
Overview
TLC339IPWR 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 across −40°C to 85°C. 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 threshold detection in battery-powered sensor interfaces.
For engineers reviewing the TLC339IPWR datasheet, TLC339IPWR pinout, TLC339IPWR application, or TLC339IPWR equivalent, key selection criteria include industrial-temperature-rated open-drain comparators with sub-100 µA quiescent current per channel, rail-to-rail input capability down to −0.2 V, and compatibility with wired-AND logic or pull-up-based level translation.
Technical Context
The TLC339IPWR implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering stable input offset voltage (7 mV max over −40°C to 85°C) and high common-mode rejection (84 dB) without sacrificing speed. Its open-drain output stage requires external pull-up and supports interfacing to mixed-voltage systems.
Unlike bipolar LM339 variants, the LinCMOS architecture enables ultra-low input bias current (5 pA typ at 25°C), enabling high-impedance sensing applications such as thermistor or photodiode monitoring without significant loading error.
Key Specifications

| Two-Phase Clock Generation | Sensor Threshold Detection |
|
Use Scenario: Generating complementary, non-overlapping clock phases for synchronous logic or switched-capacitor circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Bipolar process; 1.6 mA typical supply current; 300 ns faster propagation but 8× higher power; no negative input capability | Preferred in cost-sensitive, high-speed digital logic interfaces where supply current is not constrained | Select LM339DR only if system power budget permits >1.5 mA per comparator and input common-mode range stays ≥0 V |
| TLC3704IPWR | Push-pull output (no external pull-up required); 100 µA typical supply current; same LinCMOS process and temp range | Used where active-high outputs or reduced BOM count (no pull-up resistors) are prioritized over wired-AND flexibility | Choose TLC3704IPWR when driving CMOS loads directly or minimizing external components outweighs need for bus arbitration |
Compared with LM339DR and TLC3704IPWR, the TLC339IPWR uniquely balances ultra-low power (44 µA), industrial temperature rating, and open-drain versatility-making it optimal for battery-operated, multi-rail, or fault-tolerant monitoring systems requiring wired-AND signaling.

FAQ
What is the maximum supply voltage for the TLC339IPWR?
The TLC339IPWR supports a supply voltage range of 3 V to 16 V, with absolute maximum rating of 18 V. Operation above 16 V risks exceeding recommended conditions and may degrade long-term reliability. For 12 V systems, the device operates safely with full specification compliance and no derating required.
Does the TLC339IPWR require external pull-up resistors on its outputs?
Yes, the TLC339IPWR features open-drain CMOS outputs and requires external pull-up resistors to define the high-state voltage level. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and load capacitance requirements. Pull-up to any compatible logic rail (e.g., 3.3 V, 5 V, or 12 V) is supported.
Can the TLC339IPWR inputs operate below ground potential?
Yes-the TLC339IPWR supports a common-mode input voltage range down to −0.2 V (at VDD = 5 V), enabling direct connection to current-sense shunts or other sub-ground referenced signals without clamping diodes or level-shifting circuitry.
What is the input offset voltage specification for the TLC339IPWR over temperature?
The TLC339IPWR has a maximum input offset voltage of 7 mV across its full industrial operating range of −40°C to +85°C. At 25°C, typical offset is 1.4 mV, with worst-case drift contributing to the 7 mV limit under extreme conditions.
Is the TLC339IPWR RoHS compliant and lead-free?
Yes, the TLC339IPWR is RoHS compliant and uses NiPdAu (NIPDAU) lead finish. It meets JEDEC Level-1 moisture sensitivity requirements and is rated for peak reflow temperatures up to 260°C, supporting standard lead-free PCB assembly processes.
