Product details
Overview
TLC352IPW from Texas Instruments is a dual CMOS voltage comparator with open-drain outputs, designed for industrial-temperature (−40°C to 85°C) operation. It supports single-supply operation from 2.7V to 16V, draws only 150µA typical supply current at 5V, features 5pA typical input bias current and 5mV max input offset voltage at 25°C, and is used in battery-powered sensing, threshold detection, and level-shifting circuits.
For engineers reviewing the TLC352IPW datasheet, TLC352IPW pinout, TLC352IPW application, or TLC352IPW equivalent, key selection criteria include its ultra-low input bias current, rail-to-rail common-mode input range including ground, open-drain output compatibility with TTL/MOS/CMOS, and industrial-grade temperature rating - all critical for precision low-power analog monitoring systems.
Technical Context
The TLC352IPW integrates two independent high-impedance comparators fabricated in CMOS technology, each with differential inputs and n-channel open-drain outputs. Its input stage delivers >10¹²Ω impedance and 5pA typical bias current, enabling direct interface with high-Z sources like photodiodes or resistive sensors without loading error.
Operation is supported across 2.7V–16V single supply or dual supplies with ≤18V total difference. The open-drain outputs allow wired-AND logic, level translation up to 16V, and flexible pull-up configuration - essential for interfacing across mixed-voltage domains in embedded control and power management systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 16V single supply - enables direct use in 3.3V, 5V, and 12V systems without regulation. |
| Input Bias Current | 5pA typical at 25°C - minimizes error in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric elements). |
| Input Offset Voltage | 5mV max at 25°C - ensures reliable threshold detection within ±2.5mV accuracy under nominal conditions. |
| Supply Current (both channels) | 150µA typical at 5V - supports multi-year battery life in always-on monitoring applications. |
| Common-Mode Input Range | 0V to VDD − 1.5V over full temperature range - includes ground reference, simplifying single-supply design with grounded sensors. |
| Output Type | N-channel open-drain - allows external pull-up to voltages up to 16V, enabling logic-level translation and wired-AND bus configurations. |
| Propagation Delay | 200ns typical at 100mV overdrive (5V supply) - suitable for medium-speed event detection (e.g., overvoltage latch, zero-crossing). |
Pinout & Package
TLC352IPW is housed in an 8-pin TSSOP (PW) package, 3.0mm × 4.4mm body size, 0.65mm lead pitch, with exposed pad not electrically connected. Pin 1 is located at the top-left corner adjacent to the index mark (dot), and the device is rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Open-drain output of Comparator A - requires external pull-up; sinks current when IN+ < IN−. |
| 2 | IN− A | Inverting input of Comparator A - high-impedance node; accepts signals from 0V to VDD − 1.5V. |
| 3 | IN+ A | Non-inverting input of Comparator A - same voltage range and impedance as IN− A. |
| 4 | GND | Analog and digital ground reference - must be low-impedance return path for both comparators and load currents. |
| 5 | IN+ B | Non-inverting input of Comparator B - electrically isolated from Channel A; identical specs and range. |
| 6 | IN− B | Inverting input of Comparator B - shares no internal coupling with Channel A; supports independent thresholds. |
| 7 | OUT B | Open-drain output of Comparator B - independently controllable; supports separate pull-up networks. |
| 8 | VDD | Positive supply rail - powers both comparators; must be bypassed with ≥0.1µF ceramic capacitor near pin. |
Key Features

Use Value: 150µA supply current extends operational runtime; 5pA input bias prevents divider loading error; open-drain outputs drive discrete MOSFETs directly. |
Use Scenario: Monitoring heatsink temperature via NTC thermistor in a motor drive inverter module. IC Role / Device Role / Timing Role: One comparator detects over-temperature trip point; second channel provides hysteresis to prevent oscillation near threshold. Use Value: Rail-to-rail input range accommodates thermistor voltage spanning 0–VDD; 5mV offset ensures ±2.5mV trip accuracy across −40°C to 85°C. |
| Level-Shifting Interface | Zero-Crossing Detector |
|
Use Scenario: Translating 1.8V logic signals from an MCU to 5V or 12V control lines in industrial automation. IC Role / Device Role / Timing Role: Comparator acts as voltage-level translator with hysteresis; reference set at 0.9V, input driven by 1.8V GPIO. Use Value: Open-drain output pulled to 5V/12V enables seamless inter-voltage-domain signaling; 200ns propagation delay supports ≤5MHz signal rates. |
Use Scenario: Detecting AC line zero crossings for phase-controlled dimming in smart lighting systems. IC Role / Device Role / Timing Role: Comparator compares rectified AC waveform against ground reference to generate clean digital zero-cross pulses. Use Value: Common-mode input range including ground allows direct connection to center-tapped transformer or bridge rectifier output; low input bias avoids false triggering from leakage paths. |
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 input bias current (25nA), wider offset (7mV max), no industrial temp grade (0°C–70°C only), same SOIC-8 but not TSSOP-8 compatible. | Not suitable for precision low-current sensing or extended temperature environments; limited to commercial-grade designs. | Select LM393DR only for cost-sensitive, non-critical applications where 25nA bias and 7mV offset are acceptable. |
| TLC372IPWR | Lower supply current (75µA/channel), higher speed (1.5µs response), same TSSOP-8 package and industrial temp rating, but higher input offset (10mV max). | Better for ultra-low-power or faster-response needs, but less accurate threshold detection due to doubled offset voltage. | Choose TLC372IPWR when minimizing quiescent current is paramount and 10mV offset meets system tolerance. |
Compared with LM393DR and TLC372IPWR, TLC352IPW delivers optimal balance of precision (5mV offset), ultra-low bias (5pA), and industrial reliability - making it preferred for battery-constrained, high-accuracy analog monitoring where both accuracy and longevity matter.

FAQ
What is the maximum supply voltage for TLC352IPW?
The absolute maximum supply voltage for TLC352IPW is 18V, but the recommended operating range is 2.7V to 16V. Exceeding 16V may degrade long-term reliability or violate recommended conditions specified in the datasheet. Operation at 18V is only permissible under short-duration transient conditions and must remain within absolute maximum ratings.
Does TLC352IPW support dual-supply operation?
Yes, TLC352IPW supports dual-supply operation provided the voltage 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 not fall below −0.3V relative to GND to avoid violating absolute maximum input voltage limits.
Can TLC352IPW outputs drive LEDs directly?
No - TLC352IPW outputs are open-drain and cannot source current. To drive an LED, connect the anode to a positive supply (≤16V) and the cathode to OUTx, then select a series resistor to limit current to ≤20mA. Ensure VOL remains ≤400mV at the target sink current, per electrical characteristics at 5V supply.
Is TLC352IPW pin-compatible with TLC352IDR?
Yes - TLC352IPW (TSSOP-8) and TLC352IDR (SOIC-8) share identical pin functions and electrical specifications, but differ in package type and thermal performance. PCB layout must be redesigned for TSSOP vs. SOIC footprints; no direct socket or adapter compatibility exists without board revision.
What is the input common-mode voltage range for TLC352IPW at 12V supply?
At VDD = 12V, the guaranteed input common-mode voltage range for TLC352IPW is 0V to 10.5V (VDD − 1.5V) across the full industrial temperature range (−40°C to +85°C). This includes ground, enabling direct interface with grounded sensors or reference voltages without level-shifting circuitry.
