Product details
Overview
TLC339CD 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 low-power threshold detection in battery-powered sensor interfaces and supply monitoring circuits.
For engineers reviewing the TLC339CD datasheet, TLC339CD pinout, TLC339CD application, or TLC339CD equivalent, key selection considerations include its commercial-temperature-range (0°C to 70°C) rating, SOIC-14 package, 5-mV max input offset voltage at 25°C, open-drain output compatibility with wired-OR logic and mixed-voltage level-shifting, and LinCMOS™ process advantages in input stability and ESD robustness.
Technical Context
The TLC339CD implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering high input impedance and ultra-low bias currents without sacrificing speed. Its open-drain MOS output stage requires an external pull-up resistor and supports direct interface to TTL, CMOS, or microcontroller GPIO pins.
It operates across a wide common-mode input range (0 V to VDD−1.5 V), maintains stable offset voltage drift (0.23 µV/month), and features on-chip ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2 - making it suitable for industrial control inputs and noisy embedded environments where rail-to-rail input tolerance and long-term parametric stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct operation from 3.3 V, 5 V, or 12 V rails without regulation. |
| Input Offset Voltage (max) | 6.5 mV at 0°C to 70°C - ensures reliable switching within ±3.25 mV of threshold under full commercial temperature range. |
| Propagation Delay (typ) | 2.5 µs at 5-mV overdrive - supports fast response in motor control feedback or overvoltage latch circuits. |
| Supply Current (typ) | 44 µA at 25°C - allows integration into always-on monitoring nodes with sub-100 µA total quiescent budget. |
| Input Impedance (typ) | 10¹² Ω - minimizes loading on high-impedance sensor sources like thermistors or photodiodes. |
| Output Type | Open-drain CMOS - permits flexible pull-up to any voltage ≤18 V and wired-OR bus configuration. |
| ESD Protection | 2000 V HBM - reduces need for external transient suppression in board-level I/O protection. |

Applications
| Motor Speed Control | Supply Rail Monitoring |
|---|---|
Use Scenario: Pulse-width-modulated (PWM) control of DC motor speed using analog feedback from current sense or back-EMF. IC Role / Device Role / Timing Role: Quad comparator compares ramp waveform against error voltage to generate variable-duty-cycle PWM drive signals. Use Value: Low propagation delay (2.5 µs) enables tight loop bandwidth; open-drain outputs simplify gate-drive logic interfacing. | Use Scenario: Real-time supervision of 3.3 V, 5 V, and 12 V system rails with early warning and reset assertion. IC Role / Device Role / Timing Role: Independent comparators monitor each rail against precision reference voltages to trigger interrupt or reset lines. Use Value: 6.5 mV max input offset ensures accurate trip points; wide supply range (3 V–16 V) supports multi-rail monitoring from single device. |
| Nonoverlapping Clock Generation | Sensor Threshold Detection |
Use Scenario: Generating complementary, nonoverlapping clock phases for synchronous logic or half-bridge drivers. IC Role / Device Role / Timing Role: Two comparators configured as hysteresis oscillators produce phase-shifted square waves with controlled dead time. Use Value: LinCMOS™ input stability prevents timing jitter due to offset drift; open-drain outputs allow direct connection to logic-level shifters. | Use Scenario: Detecting temperature, light, or pressure thresholds in IoT edge nodes using resistive or capacitive sensors. IC Role / Device Role / Timing Role: Comparator compares sensor-derived voltage against fixed or programmable reference to assert digital alert. Use Value: 10¹² Ω input impedance avoids sensor loading; 44 µA typical supply current enables multi-sensor monitoring in energy-constrained designs. |
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); slower propagation delay (1.3 µs min, but 30 µs typ at low overdrive); no guaranteed 3-V operation. | Less suitable for battery-powered systems; requires higher drive strength for TTL loads; limited low-voltage headroom. | Select LM339DR only when legacy bipolar performance or higher sink current (16 mA) is required and power budget allows. |
| TLC3704CDR | Push-pull (not open-drain) outputs; identical LinCMOS™ process; same supply range and input specs; faster rise/fall times due to active pull-up. | Eliminates need for external pull-up resistors; incompatible with wired-OR buses or level-shifting; not drop-in replaceable for open-drain logic. | Choose TLC3704CDR when driving CMOS loads directly and board layout must avoid discrete pull-ups. |
Compared with LM339DR and TLC3704CDR, the TLC339CD uniquely balances ultra-low power (44 µA), rail-compatible input range (down to 3 V), and open-drain flexibility - making it optimal for modern low-power, multi-voltage embedded systems where design longevity and interface versatility are prioritized.

FAQ
What is the operating temperature range for the TLC339CD?
The TLC339CD is characterized for the commercial temperature range of 0°C to 70°C. This is explicitly defined in the "recommended operating conditions" table for TLC339C devices, and the D-package marking "TLC339CD" corresponds to the TLC339C grade per TI's packaging option addendum and device ordering matrix.
Does the TLC339CD support single-supply operation below 5 V?
Yes, the TLC339CD supports single-supply operation from 3 V to 16 V, as confirmed in the "recommended operating conditions" section for TLC339C. It functions reliably at 3.3 V, maintaining specified input offset voltage (≤6.5 mV), propagation delay (≤4.5 µs at 2-mV overdrive), and output drive capability.
What is the maximum input voltage allowed at the comparator inputs of the TLC339CD?
The absolute maximum input voltage for the TLC339CD is −0.3 V to VDD, per the "absolute maximum ratings" table. However, for proper comparator operation, inputs must remain within the common-mode input voltage range of 0 V to VDD−1.5 V - e.g., 0 V to 3.5 V when VDD = 5 V - to avoid invalid output states or increased offset error.
Can the TLC339CD drive a 10-kΩ pull-up resistor to 5 V while maintaining valid logic levels?
Yes. With IOL = 6 mA, the TLC339CD guarantees VOL ≤ 400 mV at 25°C and ≤650 mV at 70°C. Driving a 10-kΩ pull-up to 5 V draws only 0.5 mA, well within the 20-mA per-output rating, ensuring robust low-state margin (<0.4 V) and noise immunity in standard logic interfacing.
Is the TLC339CD pin-compatible with the LM339?
No - while functionally similar, the TLC339CD and LM339 share the same SOIC-14 pinout (14-pin D package, identical pin numbering per top-view diagram), but differ electrically: TLC339CD uses LinCMOS™ (CMOS input stage, open-drain output), whereas LM339 uses bipolar input and open-collector output. Direct substitution requires verification of input bias current, supply current, and output voltage compliance in the target circuit.
