Product details
Overview
TLC339IPW 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 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 industrial sensors and power-supply supervisors.
For engineers reviewing the TLC339IPW datasheet, TLC339IPW pinout, TLC339IPW application, or TLC339IPW equivalent, key selection criteria include its industrial temperature range (−40°C to +85°C), low-input-bias-current LinCMOS™ architecture, open-drain output compatibility with wired-AND logic, and verified performance under 5-mV overdrive conditions.
Technical Context
The TLC339IPW 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 MOS output stage supports flexible pull-up configurations and direct interface to TTL, CMOS, or microcontroller interrupt inputs.
Unlike bipolar comparators, the LinCMOS™ design eliminates input bias current drift and enables reliable operation with high-impedance sensor sources. The device requires no internal compensation and operates with common-mode input range extending to VDD − 1.5 V, supporting rail-to-rail sensing in 3-V to 16-V systems.

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 input stage; higher supply current (500 µA typ); slower response (1.3 µs min at 5-V supply but degrades below 5 V). | Less suitable for battery-powered or low-voltage (3–5 V) systems; requires tighter layout for noise immunity due to lower input impedance. | Select LM339DR only if legacy design reuse or cost sensitivity outweighs power/performance requirements. |
| TLC3704IPW | Push-pull output (not open-drain); identical LinCMOS™ core; same pinout except output logic polarity differs. | Cannot perform wired-AND; requires level-shifting for mixed-voltage interfacing; better for driving LEDs or logic gates directly. | Choose TLC3704IPW when active-high outputs or direct LED driving are required; not drop-in for open-drain designs. |
Compared with LM339DR and TLC3704IPW, the TLC339IPW uniquely balances ultra-low power (200 µW), industrial temperature support, and open-drain flexibility - making it optimal for space- and energy-constrained industrial sensing where wired logic or multi-rail interfacing is needed.

FAQ
What is the maximum operating temperature range for the TLC339IPW?
The TLC339IPW is specified for operation from −40°C to +85°C, meeting industrial temperature requirements. This range is validated per TI's characterization data and applies to all electrical parameters including propagation delay, input offset voltage (≤7 mV max), and supply current (≤125 µA). The TSSOP package supports standard reflow profiles with MSL Level-1 rating.
Does the TLC339IPW support single-supply operation below 5 V?
Yes, the TLC339IPW supports single-supply operation from 3 V to 16 V. At 3 V, it maintains functional performance including 2.5 µs typical propagation delay (with appropriate overdrive) and input common-mode range down to 0 V. The LinCMOS™ process ensures stable operation even at minimum supply, unlike many bipolar comparators that degrade below 5 V.
Can the TLC339IPW outputs drive a 10-kΩ pull-up resistor to 12 V?
Yes, the TLC339IPW open-drain outputs can sink up to 20 mA each and tolerate up to 16 V on the drain side. With a 10-kΩ pull-up to 12 V, the output low voltage remains ≤700 mV at 85°C (per datasheet VOL spec), ensuring clean TTL/CMOS-compatible logic levels. Total ground current must stay ≤60 mA - limiting simultaneous sinking across all four outputs.
How does the LinCMOS™ process benefit the TLC339IPW in sensor applications?
The LinCMOS™ process gives the TLC339IPW 10¹² Ω typical input impedance and ≤2 nA input bias current at 85°C - preventing loading errors in high-impedance sensor circuits (e.g., thermistors, pH electrodes, photodiodes). It also delivers exceptional offset voltage stability (<0.23 µV/month), critical for long-term calibration integrity in measurement systems.
Is the TLC339IPW pin-compatible with the LM339?
No, the TLC339IPW is not pin-compatible with the LM339. While both are quad comparators in 14-pin packages, the TLC339IPW uses TSSOP (PW) packaging with different pin assignments than the LM339's PDIP or SOIC variants. More critically, the TLC339IPW's LinCMOS™ architecture requires different bypassing and layout practices - especially regarding input protection and ground decoupling - to achieve specified performance.
