Product details
Overview
TLC339IDRG4 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 precision threshold detection in battery-powered industrial sensors and power-supply supervisors.
For engineers reviewing the TLC339IDRG4 datasheet, TLC339IDRG4 pinout, TLC339IDRG4 application, or TLC339IDRG4 equivalent, key selection criteria include its industrial temperature range (−40°C to +85°C), rail-to-rail input common-mode range (down to −0.2 V), low input offset voltage (7 mV max), and compatibility with wired-AND logic and pull-up resistor configurations.
Technical Context
The TLC339IDRG4 implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering CMOS-level power efficiency without sacrificing speed or input stability. Its input stage maintains high impedance and low bias current (≤5 pA typ at 25°C) while sustaining stable offset voltage drift (0.23 µV/month).
Each comparator features an open-drain output stage capable of sinking up to 20 mA per channel, with total ground current limited to 60 mA. The device requires external pull-up resistors and supports wired-logic functions, unlike push-pull alternatives such as the TLC3704.

Applications
| Motor Speed Control | Power Supply Supervision |
|---|---|
Use Scenario: Pulse-width-modulated control of DC motor speed using potentiometer-adjusted reference and sensed back-EMF feedback. IC Role / Device Role / Timing Role: Quad comparator implements error amplifier, direction latch, enable gate, and overcurrent trip in single IC. Use Value: Reduces component count by replacing four discrete comparators; 2.5 µs response enables tight PWM loop bandwidth up to 100 kHz. |
Use Scenario: Monitoring 5 V and 12 V rails for brown-out, overvoltage, and early fail warning in embedded controllers. IC Role / Device Role / Timing Role: Configured as window comparator (rails) and threshold detector (early fail) with interrupt and reset outputs. Use Value: 7 mV max offset ensures accurate 5 V ±2% detection; open-drain outputs directly drive µP reset/interrupt pins with no level translation. |
| Nonoverlapping Clock Generation | Industrial Sensor Interface |
Use Scenario: Generating two-phase, nonoverlapping clocks for stepper motor drivers or synchronous rectifiers. IC Role / Device Role / Timing Role: Three comparators form oscillator core and phase splitter; fourth provides dead-time control. Use Value: LinCMOS™ low input bias avoids timing drift from RC network leakage; 200 µW quiescent power enables always-on clock gen. |
Use Scenario: Converting analog outputs from RTDs, thermocouples, or strain gauges into digital status flags for PLC I/O modules. IC Role / Device Role / Timing Role: Threshold detector for alarm conditions (e.g., overtemperature, overload) with hysteresis added externally. Use Value: 10¹² Ω input impedance prevents loading of high-Z sensor bridges; −40°C to +85°C rating matches industrial ambient requirements. |
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; 1.6 mA typical supply current; 300 ns faster propagation but 8× higher power; no sub-ground input capability. | Suitable for high-speed, AC-coupled signal conditioning where power is not constrained. | Select LM339DR only if speed >1 µs is mandatory and supply current >1 mA is acceptable. |
| TLC3704CDR | Same LinCMOS™ process; push-pull outputs (no external pull-up needed); 10 mV max offset; 1.5 µs propagation delay. | Preferred where driving TTL loads directly or minimizing external components is critical. | Choose TLC3704CDR when open-drain flexibility is unnecessary and board space for pull-ups must be avoided. |
Compared with LM339DR and TLC3704CDR, the TLC339IDRG4 uniquely balances ultra-low power (125 µA max), sub-µV/month offset stability, and −0.2 V input capability - making it optimal for battery-operated industrial monitors requiring long-term accuracy and wide supply tolerance.

FAQ
What is the operating temperature range for the TLC339IDRG4?
The TLC339IDRG4 is specified for industrial temperature operation from −40°C to +85°C. This range is validated per TI's characterization data and applies to all electrical parameters in the datasheet, including input offset voltage (7 mV max), supply current (125 µA max), and propagation delay (2.5 µs typ). The "I" suffix explicitly denotes this industrial grade, distinguishing it from commercial (C) or military (M) variants.
Does the TLC339IDRG4 require external pull-up resistors on its outputs?
Yes, the TLC339IDRG4 features open-drain CMOS outputs and requires external pull-up resistors on each output pin (Pins 1, 6, 8, 13) to establish a defined high state. Typical values range from 2.2 kΩ to 10 kΩ, selected based on rise time requirements and load capacitance. Without pull-ups, outputs remain floating when inactive - a fundamental design requirement confirmed in the TI datasheet Figure 3 test circuit and Application Information section.
Can the TLC339IDRG4 accept input voltages below ground (negative inputs)?
Yes, the TLC339IDRG4 supports common-mode input voltages down to −0.2 V (relative to GND) at 25°C, and down to 0 V over the full −40°C to +85°C range. This capability is explicitly stated in the "Recommended Operating Conditions" table for the TLC339I variant and enables direct interfacing with current-sense amplifiers or transducers that produce small negative signals - a feature absent in standard bipolar comparators like the LM339.
How does the TLC339IDRG4 differ from the TLC339CDR in terms of performance?
The TLC339IDRG4 and TLC339CDR share identical electrical architecture and pinout but differ in temperature grading and offset voltage limits: TLC339IDRG4 is rated for −40°C to +85°C with 7 mV max input offset, while TLC339CDR is commercial-grade (0°C to +70°C) with 6.5 mV max offset. Both use the same SOIC-14 (D) package and LinCMOS™ process; the "I" vs "C" suffix defines the qualified operating range and associated parameter limits.
Is the TLC339IDRG4 pin-compatible with the LM339 series?
Yes, the TLC339IDRG4 is pin-compatible with the LM339, LM239, and LM2901 in the SOIC-14 (D) package, sharing identical pin assignments for VDD (Pin 14), GND (Pin 7), and all four comparator inputs/outputs. However, due to its CMOS input stage, designers must verify that input source impedance and common-mode range comply with TLC339IDRG4 specifications - particularly the −0.2 V minimum input voltage and absence of internal clamping diodes found in bipolar LM339 devices.
