Product details
Overview
TLC352IDG4 from Texas Instruments is a dual CMOS voltage comparator with open-drain outputs, designed for low-power, wide-supply applications including battery-powered systems and industrial sensing interfaces. It operates from 2.7V to 18V single or dual supply, delivers 5 mV max input offset voltage at 25°C, draws only 150 µA typical supply current at 5V, and supports common-mode input down to ground - enabling direct interface with high-impedance sensors.
For engineers reviewing the TLC352IDG4 datasheet, TLC352IDG4 pinout, TLC352IDG4 application, or TLC352IDG4 equivalent, key selection criteria include its industrial temperature range (−40°C to 85°C), ultra-low 5 pA typical input bias current, 10¹² Ω input impedance, 200 ns typical response time, and compatibility with TTL/MOS/CMOS logic families via external pull-up.
Technical Context
The TLC352IDG4 integrates two independent comparators fabricated in CMOS technology, each featuring rail-to-rail input capability with common-mode range extending to V− (ground) and up to VDD − 1.5 V across full temperature. Its open-drain output stage allows flexible logic-level translation and wired-AND configurations without internal pull-ups.
Input stage design delivers extremely high DC precision: 5 pA typical input bias current and 5 mV max input offset voltage over temperature ensure stable threshold detection in precision analog monitoring circuits. ESD protection is built-in (2000 V HBM), and operation down to 2.7 V enables use in modern low-voltage embedded systems.

Applications
| Overvoltage Protection Circuit | Battery State-of-Charge Monitor |
|---|---|
Use Scenario: Detecting when a 12 V automotive rail exceeds 13.8 V to trigger shutdown or warning LED. IC Role / Device Role / Timing Role: Dual comparator compares sensed rail against precision reference; one channel monitors upper limit, second validates hysteresis window. Use Value: 5 mV offset and 200 ns response enable reliable trip-point accuracy and fast fault response without external op-amps. | Use Scenario: Monitoring lithium-ion cell voltage during charging/discharging to determine end-of-charge or low-battery cutoff. IC Role / Device Role / Timing Role: TLC352IDG4 compares cell voltage against two thresholds (e.g., 4.2 V full, 3.0 V empty) using resistive dividers. Use Value: 2.7 V minimum supply and 150 µA quiescent current allow direct operation from the monitored cell stack. |
| Programmable Logic Threshold Detector | Industrial Sensor Interface |
Use Scenario: Converting analog sensor output (e.g., 0–10 V pressure transducer) into clean digital logic for PLC input modules. IC Role / Device Role / Timing Role: Comparator acts as voltage-level translator; open-drain outputs interface directly with 24 V PLC inputs via pull-up resistor. Use Value: Open-drain architecture supports 0–24 V logic translation independent of VDD, eliminating level-shifter ICs. | Use Scenario: Conditioning output from a 4–20 mA loop-powered temperature transmitter for microcontroller ADC input. IC Role / Device Role / Timing Role: TLC352IDG4 detects fault conditions (open/short loop) by comparing shunt voltage against fixed thresholds. Use Value: 10¹² Ω input impedance prevents loading of precision current-sense resistor; −40°C to +85°C rating matches industrial ambient requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher 2.0 mV typical offset, 500 µA supply current, bipolar process - less precise and less efficient | Limited to 0°C to 70°C; unsuitable for extended industrial environments | Choose LM393DR only for cost-sensitive, non-critical consumer applications where power and precision are secondary |
| TLC372IDR | Same CMOS process, lower 1.5 mV max offset, but 100 µA supply current - improved DC accuracy at slightly lower power | Identical industrial temp range and pinout; optimized for ultra-low-offset designs | Select TLC372IDR when sub-2 mV offset is mandatory, accepting minor layout rework for same SOIC-8 footprint |
Compared with LM393DR and TLC372IDR, the TLC352IDG4 offers best-in-class trade-off between low power (150 µA), industrial temperature support, and robust 5 mV offset spec - making it optimal for battery-powered industrial sensors where longevity and reliability are critical.

FAQ
What is the operating temperature range of the TLC352IDG4?
The TLC352IDG4 is rated for industrial operation from −40°C to +85°C. This specification is validated per TI's characterization data and applies across all electrical parameters in the recommended operating conditions table. The "I" suffix in TLC352IDG4 explicitly denotes this extended temperature grade, distinguishing it from the commercial-grade TLC352CD variants.
Does the TLC352IDG4 require external pull-up resistors on its outputs?
Yes, the TLC352IDG4 features open-drain outputs that must be pulled up externally to define the logic HIGH level. TI recommends pull-up currents between 100 µA and 1 mA - typically achieved with 10 kΩ to 100 kΩ resistors depending on VPU and speed requirements. Without a pull-up, OUT A and OUT B remain floating and cannot drive logic HIGH states.
Can the TLC352IDG4 operate from a single 3.3 V supply?
Yes, the TLC352IDG4 supports single-supply operation down to 2.7 V, making it fully compatible with 3.3 V systems. At 3.3 V, it maintains 5 pA typical input bias current and 200 ns response time, while drawing approximately 100 µA supply current - ideal for low-voltage IoT sensor nodes and portable instrumentation.
Is the TLC352IDG4 pin-compatible with the LM393?
Yes, the TLC352IDG4 is pin-compatible with the LM393 in the SOIC-8 (D) package. Both devices share identical pin assignments for GND, VDD, IN+, IN−, and open-drain outputs. However, the TLC352IDG4 uses CMOS technology versus LM393's bipolar process - resulting in lower power, higher input impedance, and wider supply range.
What is the maximum input common-mode voltage for the TLC352IDG4 at 5 V supply?
At VDD = 5 V, the TLC352IDG4 supports a common-mode input voltage range of 0 V to 3.5 V (VDD − 1.5 V) across full temperature. This allows direct interface with ground-referenced signals and mid-rail references without clamping diodes or level shifters - a key advantage over many legacy comparators.
