Product details
Overview
TLC352IDR 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 16V single supply (or ±13.5V dual), draws only 150µA typical at 5V, features 5mV max input offset voltage at 25°C, and supports common-mode input down to ground.
For engineers reviewing the TLC352IDR datasheet, TLC352IDR pinout, TLC352IDR application, or TLC352IDR equivalent, this page delivers verified technical context, industrial-temperature performance data (−40°C to 85°C), SOIC-8 package details, and real-world comparator design considerations - all critical for precision threshold detection, window comparators, and power-monitoring circuits.
Technical Context
The TLC352IDR implements two independent high-impedance CMOS differential comparators with n-channel open-drain outputs. Its input stage delivers 10¹²Ω typical impedance and 5pA typical input bias current, enabling direct connection to high-Z sources like thermistors or photodiodes without loading error.
Each comparator supports rail-to-rail common-mode input down to ground and up to VDD − 1.5V across full temperature range. Output logic levels are externally pulled up to voltages up to 16V, decoupled from VDD - enabling level translation between 3.3V logic and 12V control rails in mixed-voltage systems.
Key Specifications

Applications
| Battery Voltage Monitor | Industrial Threshold Detector |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger low-battery warning or cutoff. IC Role / Device Role / Timing Role: Dual comparator configures hysteresis-based window detector - one channel for under-voltage lockout (UVLO), second for over-voltage protection (OVP). Use Value: 5mV offset and 150µA supply current enable accurate 3.0V/4.2V thresholds with negligible impact on battery drain. | Use Scenario: Detecting out-of-tolerance analog sensor outputs (e.g., 4–20mA loop current, RTD bridge voltage) in PLC I/O modules. IC Role / Device Role / Timing Role: Precision comparator compares conditioned sensor signal against programmable reference; open-drain output drives optocoupler input. Use Value: −40°C to +85°C rating and 10¹²Ω input impedance ensure stable operation across factory environments without calibration drift. |
| Power Sequencing Controller | Zero-Crossing Detector |
Use Scenario: Enforcing strict power-up/down order for multi-rail FPGAs or ASICs by monitoring individual supply voltages. IC Role / Device Role / Timing Role: Each comparator monitors one rail (e.g., 1.2V core, 3.3V I/O); outputs feed AND gate to enable next-stage regulator. Use Value: Rail-to-rail input range and 200ns response time allow reliable detection of 1.2V ramp edges without external amplification. | Use Scenario: Converting AC line voltage into clean digital zero-crossing pulses for TRIAC phase-control dimmers or SMPS synchronization. IC Role / Device Role / Timing Role: One comparator compares rectified AC waveform against ground; hysteresis prevents noise-induced chatter near zero crossing. Use Value: Ground-sensing capability and 5pA bias current eliminate need for DC-blocking capacitors or bias resistors in transformerless designs. |
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 supply current (500µA), wider offset (7mV max), no guaranteed operation below 3V | Less suitable for battery-critical or low-voltage (<3V) designs; acceptable for 5V industrial controls | Select LM393DR only when cost is primary constraint and 3V operation or micro-power is not required. |
| TLC372IDR | Same SOIC-8 package, lower supply current (75µA/channel), but higher offset (10mV max) and reduced ESD rating (1500V) | Better for ultra-low-power applications where 10mV offset is acceptable; less robust in ESD-prone environments | Choose TLC372IDR when minimizing quiescent current is critical and industrial ESD immunity is secondary. |
Compared with LM393DR and TLC372IDR, the TLC352IDR uniquely balances low 150µA supply current, 5mV precision, 2000V ESD rating, and guaranteed 2.7V operation - making it optimal for battery-powered industrial sensors requiring long life and reliability.

FAQ
What is the maximum supply voltage for the TLC352IDR?
The TLC352IDR supports a maximum supply voltage of 16V under recommended operating conditions. Absolute maximum rating is 18V, but sustained operation above 16V risks reliability degradation. This 16V limit enables safe use with standard 12V industrial rails and regulated 15V supplies without derating.
Does the TLC352IDR support dual-supply operation?
Yes, the TLC352IDR supports dual-supply operation provided the difference between VDD and GND remains within 2.7V to 18V. For example, it can operate with +5V and −5V supplies (10V total), but the negative rail must be connected to GND or a valid reference - the device does not support true split-rail inputs relative to mid-supply.
Can the TLC352IDR outputs drive a 5V logic input directly?
No - the TLC352IDR has open-drain outputs and cannot source current. To interface with 5V logic, an external pull-up resistor to 5V must be used on each output. The value should be selected to limit sink current to ≤16mA while maintaining VOL ≤400mV at 5V supply, typically 10kΩ to 100kΩ.
What is the input common-mode voltage range for the TLC352IDR at 12V supply?
At VDD = 12V, the TLC352IDR supports a common-mode input voltage range of 0V to 10.5V (VDD − 1.5V) across its full −40°C to +85°C operating range. This includes ground-referenced signals and allows direct connection to most buffered sensor outputs without level shifting.
Is the TLC352IDR pin-compatible with the LM393?
Yes, the TLC352IDR is pin-compatible with the LM393 in the SOIC-8 (D) package. Both share identical pin assignments for VDD, GND, IN+, IN−, and open-drain outputs. However, the TLC352IDR offers lower supply current, tighter offset voltage, and enhanced ESD protection - enabling direct replacement without PCB changes.
