Use Scenario: Pulse-width modulated (PWM) motor driver uses comparator outputs to generate direction and enable signals based on potentiometer and current-sense feedback. IC Role / Device Role / Timing Role: TLC339CPW compares analog sensor voltages against reference thresholds to determine motor state transitions and fault conditions. Use Value: Low propagation delay (2.5 µs) ensures timely response to overcurrent events; open-drain outputs interface directly with half-H bridge drivers (e.g., SN75603/4). |
Use Scenario: Monitors 5 V and 12 V rails in embedded systems to trigger microcontroller reset or early power-fail interrupts before brownout. IC Role / Device Role / Timing Role: TLC339CPW acts as precision window comparator detecting undervoltage/overvoltage conditions on multiple supply lines simultaneously. Use Value: 7 mV max input offset and 84 dB CMRR ensure accurate trip points across temperature; 3 V min supply enables operation during pre-regulator startup. |
| Nonoverlapping Clock Generation | Threshold Detection in Sensor Interfaces |
|
Use Scenario: Generates two-phase, nonoverlapping clock signals for synchronous logic or switched-capacitor circuits using RC oscillator feedback. IC Role / Device Role / Timing Role: TLC339CPW functions as hysteresis-enabled oscillator core, where comparator outputs drive cross-coupled RC networks. Use Value: Stable input bias current (<0.6 nA at 70°C) prevents timing drift in high-impedance RC timing networks; low IDD extends battery life in portable instruments. |
Use Scenario: Detects light intensity thresholds from photodiode amplifiers or temperature thresholds from thermistor dividers in environmental monitoring nodes. IC Role / Device Role / Timing Role: TLC339CPW serves as analog front-end decision element converting continuous sensor outputs into digital event flags. Use Value: 10¹² Ω input impedance avoids signal attenuation in high-Z sensor paths; wide supply range (3–16 V) supports direct integration with varied transducer interfaces. |
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 quiescent current (500 µA vs. 80 µA), bipolar process, no ESD rating specified, 2 mV higher typical offset. | Less suitable for battery-powered or high-precision industrial monitoring due to power and drift limitations. | Select LM339DR only when legacy compatibility or cost sensitivity outweighs low-power and long-term stability requirements. |
| TLC3704IPW | Push-pull output (vs. open-drain), identical LinCMOS™ process, same supply range and temperature grade, but lacks wired-logic capability. | Preferred where active-high outputs simplify interface with microcontrollers lacking external pull-ups or requiring direct drive. | Choose TLC3704IPW when system architecture mandates push-pull signaling and no wired-AND functionality is needed. |
Compared with LM339DR and TLC3704IPW, the TLC339CPW uniquely balances ultra-low power, industrial temperature tolerance, open-drain flexibility, and proven long-term offset stability - making it optimal for precision, energy-conscious comparator applications where reliability across thermal cycles is critical.

FAQ
What is the operating temperature range for the TLC339CPW?
The TLC339CPW is rated for industrial operation from −40°C to +85°C. This range is explicitly confirmed in the "AVAILABLE OPTIONS" table and "recommended operating conditions" section of the official datasheet (SLCS119B), where TLC339IPW and TLC339CPW share identical temperature grading and 5 mV max input offset voltage specification across that span.
Does the TLC339CPW support single-supply operation below 5 V?
Yes, the TLC339CPW supports single-supply operation down to 3 V, as stated in the "recommended operating conditions" table for the TLC339C and TLC339I variants. This enables direct use with modern 3.3 V microcontrollers and low-voltage sensor interfaces without level-shifting circuitry.
What is the maximum sink current per output of the TLC339CPW?
Each open-drain output of the TLC339CPW can sink up to 20 mA, as specified in the "absolute maximum ratings" table. However, total current out of GND is limited to 60 mA - meaning simultaneous full-load sinking on more than three outputs exceeds this limit and must be avoided in design.
Is the TLC339CPW pin-compatible with the LM339?
No, the TLC339CPW is not pin-compatible with the LM339. While both are quad comparators, the TLC339CPW uses a TSSOP-14 package with different pin assignments (e.g., GND on pin 7, VDD on pin 14), whereas standard LM339 packages (SOIC-14, PDIP-14) place GND on pin 4 and VDD on pin 12 - requiring PCB layout revision for substitution.
Why does the TLC339CPW require an external pull-up resistor on each output?
The TLC339CPW features open-drain CMOS outputs, which can only actively pull low - they cannot source current or drive high. An external pull-up resistor (typically 2.2 kΩ to 10 kΩ to VDD or another logic rail) is mandatory to establish a defined high logic level and enable wired-AND functionality or level translation in mixed-voltage systems.
