Overview
TLC352IDRG4 from Texas Instruments is a dual CMOS voltage comparator with open-drain outputs, designed for low-power industrial sensing and battery-powered threshold detection. It operates from 2.7V to 18V single supply, draws 150µA typical supply current at 5V, features 5pA typical input bias current and 5mV max input offset voltage at 25°C, and supports −40°C to 85°C operation in an 8-pin SOIC package.
For engineers reviewing the TLC352IDRG4 datasheet, TLC352IDRG4 pinout, TLC352IDRG4 application, or TLC352IDRG4 equivalent, this page delivers verified electrical specs, industrial-temperature performance data, open-drain output design guidance, and pin-compatible alternatives for precision analog thresholding circuits.
Technical Context
The TLC352IDRG4 integrates two independent high-impedance CMOS comparators with rail-to-rail common-mode input range including ground. Its n-channel open-drain outputs enable wired-AND logic and level translation up to 16V independent of VDD.
It delivers 200ns typical propagation delay at 5V with 100mV overdrive, maintains ultra-low input bias current (5pA typ) across temperature, and includes built-in ESD protection rated at 2000V per HBM - critical for robustness in noisy industrial environments.

Use Value: 5mV max offset and 200ns response ensure accurate trip points and fast fault isolation in 24V industrial systems. | Use Scenario: Detects end-of-life voltage in 3.7V Li-ion or 9V alkaline battery packs for portable instruments. IC Role / Device Role / Timing Role: Comparator compares battery voltage against stable reference; open-drain output drives MCU interrupt or LED driver. Use Value: 150µA supply current extends battery life; 2.7V minimum supply allows operation down to near-dead battery voltage. |
| Temperature Threshold Monitor | Zero-Crossing Detector for AC Sensing |
Use Scenario: Interfaces with NTC thermistor networks in HVAC controllers and industrial ovens to activate cooling or heating stages. IC Role / Device Role / Timing Role: Compares thermistor divider output against fixed reference; hysteresis prevents chatter near setpoint. Use Value: 5pA input bias avoids self-heating errors in high-resistance thermistor strings; −40°C to 85°C rating matches sensor operating envelope. | Use Scenario: Converts 50/60Hz AC line voltage into clean digital zero-crossing pulses for phase-controlled dimmers and SMPS synchronization. IC Role / Device Role / Timing Role: One comparator channel detects rising/falling edges of rectified AC; open-drain output interfaces directly with 3.3V microcontroller GPIO. Use Value: Rail-to-rail input range accepts AC-derived signals referenced to GND; 200ns propagation delay ensures sub-degree timing accuracy at 60Hz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Bipolar input stage; 250nA input bias current vs. TLC352IDRG4's 5pA; 2mV typical offset vs. 5mV max. | Lower cost but unsuitable for high-impedance sensor interfaces; higher supply current (500µA) limits battery use. | Select LM393DR only for cost-sensitive, non-battery, non-high-Z applications where 250nA bias is acceptable. |
| TLC372CDR | Same CMOS process; 10pA input bias; 10mV max offset; identical SOIC-8 package and pinout. | Higher offset tolerance reduces precision in tight-threshold designs; otherwise drop-in replacement for less demanding industrial use. | Choose TLC372CDR when 10mV offset is sufficient and legacy design reuse is prioritized over lowest possible bias current. |
Compared with LM393DR and TLC372CDR, the TLC352IDRG4 delivers superior input impedance and bias current for sensor front-ends, while maintaining industrial temperature range and open-drain compatibility - making it optimal for precision, low-power, and mixed-voltage systems.

FAQ
What is the maximum supply voltage for the TLC352IDRG4?
The TLC352IDRG4 supports a maximum supply voltage of 18V on the VDD pin. Absolute maximum ratings specify VDD ≤ 18V; operation beyond this risks permanent device damage. Recommended operating conditions limit VDD to 16V for sustained reliability, especially at elevated temperatures. The TLC352IDRG4 maintains full functionality across its 2.7V–16V operating range, making it suitable for 12V industrial rails and 3.3V/5V logic systems.
Does the TLC352IDRG4 have push-pull or open-drain outputs?
The TLC352IDRG4 features open-drain (n-channel) outputs on both channels. Neither output can source current - they only sink current when active LOW. An external pull-up resistor is required to establish a logic HIGH level, and the pull-up voltage may be up to 16V, independent of the VDD supply. This architecture enables wired-AND logic, level translation, and interface with mixed-voltage systems - a key differentiator from push-pull comparators like the LM339.
What is the input offset voltage specification for the TLC352IDRG4?
The TLC352IDRG4 has a maximum input offset voltage of 5mV at 25°C, with typical values of 1mV at 5V supply. Over the full industrial temperature range (−40°C to +85°C), the offset remains within 7mV. This specification is guaranteed per device and applies to both comparators independently. Low offset ensures accurate threshold detection in precision applications such as battery end-of-charge monitoring and sensor signal conditioning where sub-10mV error budgets are required.
Can the TLC352IDRG4 operate from a single 3.3V supply?
Yes, the TLC352IDRG4 is fully specified to operate from a single 3.3V supply. Its 2.7V minimum supply voltage allows reliable function at 3.3V across the full −40°C to +85°C temperature range. At 3.3V, supply current is ~75µA per channel (150µA total), propagation delay is ~250ns, and input common-mode range extends from GND to ~1.8V. This makes the TLC352IDRG4 ideal for modern low-voltage embedded systems interfacing with 3.3V MCUs and sensors.
Is the TLC352IDRG4 pin-compatible with the LM393?
Yes, the TLC352IDRG4 is pin-compatible with the LM393 in the SOIC-8 (D) package. Pin assignments for VDD, GND, IN+, IN−, and OUT match identically between the two devices. However, the TLC352IDRG4 uses CMOS input stages (5pA bias) versus bipolar (250nA) in the LM393, and features lower supply current (150µA vs. 500µA). Designers may substitute the TLC352IDRG4 directly into LM393 layouts but must verify pull-up resistor values and hysteresis networks due to differing input characteristics.
