Product details
Overview
TLC339CNSR 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 and power supervision circuits.
For engineers reviewing the TLC339CNSR datasheet, TLC339CNSR pinout, TLC339CNSR application, or TLC339CNSR equivalent, key selection considerations include its commercial-temperature-grade (0°C to 70°C) performance, open-drain output compatibility with wired-AND logic and mixed-voltage systems, low input bias current (<5 pA at 25°C), and LinCMOS™ process stability under differential input stress.
Technical Context
The TLC339CNSR implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering high input impedance and ultra-low input bias current while maintaining robust common-mode rejection (84 dB) and supply-voltage rejection (85 dB) across its operating range. Its open-drain output stage requires external pull-up and supports interfacing to TTL, CMOS, or mixed-voltage buses.
Unlike bipolar comparators, the LinCMOS™ architecture eliminates phase reversal under overdrive and ensures stable offset voltage drift (0.23 µV/month including first 30 days). The device operates without internal current limiting, requiring careful design of output load and ground-current paths to stay within absolute maximum ratings (e.g., 60 mA total sink current).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 3 V to 16 V - enables direct use with Li-ion, 5 V, and 12 V rails without level-shifting. |
| Propagation delay (tPLH/tPHL) | 2.5 µs typ at 5-mV overdrive - supports fast threshold detection in motor control and PWM timing loops. |
| Input offset voltage (max) | 6.5 mV over 0°C to 70°C - defines minimum detectable differential voltage in precision zero-crossing or window-comparator designs. |
| Input bias current (max) | 0.6 nA at 70°C - minimizes error in high-impedance sensor interfaces (e.g., thermistors, photodiodes). |
| Supply current (IDD) | 100 µA max over full temperature range - allows continuous operation in always-on battery monitoring applications. |
| Output type | Open-drain CMOS - permits flexible pull-up voltage selection (up to 18 V) and wired-logic bus sharing. |
| Common-mode input range | 0 V to VDD−1.5 V - supports rail-to-rail sensing when referenced to system ground or mid-supply. |
Pinout & Package
SOP (NS) package, 14-pin, surface-mount, RoHS-compliant, tape-and-reel (2000 pcs/reel), MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain output of comparator 1 - requires external pull-up; sinks up to 20 mA. |
| 2 | IN1− | Inverting input of comparator 1 - accepts voltages from −0.2 V to VDD−1.5 V. |
| 3 | IN1+ | Non-inverting input of comparator 1 - same common-mode range as IN1−. |

| 5 | IN2+ | Non-inverting input of comparator 2 - supports independent reference or signal routing. |
| 6 | GND | Ground reference for all comparators and supply return - must be low-impedance for stable operation. |
| 7 | IN3+ | Non-inverting input of comparator 3 - used in multi-threshold detection schemes (e.g., triple-voltage supervisor). |
| 8 | IN3− | Inverting input of comparator 3 - paired with IN3+ for differential or single-ended comparison. |
| 9 | VDD | Positive supply rail - powers all four comparators; decoupling capacitor (0.1 µF) required near pin. |
| 10 | IN4− | Inverting input of comparator 4 - supports fourth independent decision channel. |

Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ process technology | Enables 10¹² Ω input impedance and sub-picoampere bias current - critical for high-Z sensor front-ends. |
| Single-supply operation down to 3 V | Eliminates need for dual supplies in portable and automotive subsystems powered by 3.3 V or higher rails. |
| ESD protection (2000 V HBM) | Reduces handling sensitivity and improves field reliability without external protection diodes. |
| Stable input offset voltage | Drift limited to 0.23 µV/month - ensures long-term accuracy in calibration-critical applications like power supply monitors. |
| No phase reversal under overdrive | Guarantees predictable output polarity even when inputs exceed common-mode range - simplifies fault-tolerant design. |

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; 2 mA typical supply current; 300 ns faster propagation but 10× higher power; no ESD rating specified. | Higher drive strength (16 mA sink) but incompatible with ultra-low-power designs; less stable offset vs temperature. | Select LM339DR only when speed >2 µs is mandatory and supply current >100 µA is acceptable. |
| TLC3704CDR | Push-pull output (no external pull-up needed); 1.5 µs propagation; 50 µA supply current; same LinCMOS™ process. | Eliminates pull-up resistors but cannot perform wired-AND; unsuitable for mixed-voltage bus interfacing. | Choose TLC3704CDR when board space is constrained and open-drain flexibility is not required. |
Compared with LM339DR and TLC3704CDR, the TLC339CNSR uniquely balances ultra-low power (100 µA max), open-drain versatility, and LinCMOS™ stability - making it optimal for battery-sensitive, multi-rail, or noise-immune comparator applications where external pull-up overhead is acceptable.

FAQ
What is the maximum operating temperature range for the TLC339CNSR?
The TLC339CNSR is rated for the commercial temperature range of 0°C to 70°C. This specification is defined in the "recommended operating conditions" section of the datasheet and applies across all electrical parameters unless otherwise noted. Operation outside this range may result in parametric degradation or functional failure. For extended temperature grades, consider the TLC339IDR (−40°C to 85°C) or TLC339QDR (−40°C to 125°C) variants.
Does the TLC339CNSR require external pull-up resistors on its outputs?
Yes, the TLC339CNSR features open-drain CMOS outputs that require external pull-up resistors to establish a valid high logic level. Each output can sink up to 20 mA, and the pull-up voltage may be set independently - even above VDD (up to 18 V) - enabling level translation. Without a pull-up, the output remains floating and cannot drive logic-high signals reliably.
Can the TLC339CNSR operate from a 3.3 V supply?
Yes, the TLC339CNSR 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 propagation delay increases slightly (to ~3.2 µs typ at 5-mV overdrive), and its common-mode input range becomes 0 V to 1.8 V. Input bias current remains below 1 pA at 25°C, preserving accuracy in low-voltage sensor interfaces.
What is the input offset voltage specification for the TLC339CNSR?
The TLC339CNSR has a maximum input offset voltage of 6.5 mV over its full operating temperature range (0°C to 70°C), with a typical value of 1.4 mV at 25°C. This parameter is measured under specified test conditions (VIC = VICRmin, VDD = 5 V to 10 V) and defines the smallest differential input voltage required to switch the output state reliably.
Is the TLC339CNSR pin-compatible with the LM339?
No, the TLC339CNSR is not pin-compatible with the LM339. While both are quad comparators in 14-pin packages, the TLC339CNSR uses an SOP (NS) package with a different pinout - specifically, GND is on pin 6 and VDD on pin 9, whereas the LM339 places GND on pin 4 and VDD on pin 12 in its SOIC (D) variant. Direct replacement requires PCB layout revision.
