Product details
Overview
TLC352ID from Texas Instruments is a dual CMOS voltage comparator with open-drain outputs, designed for low-power industrial sensing and battery-powered monitoring systems. It operates from 2.7V to 16V single supply, delivers 5mV max input offset voltage at 25°C, draws only 150µA typical supply current at 5V, and supports −40°C to +85°C operation in an SOIC-8 package.
For engineers reviewing the TLC352ID datasheet, TLC352ID pinout, TLC352ID application, or TLC352ID equivalent, this page provides verified electrical specifications, industrial-temperature performance data, open-drain output design guidance, and pin-compatible alternatives for precision analog threshold detection circuits.
Technical Context
The TLC352ID implements two independent high-impedance (10¹²Ω typical) CMOS comparators with rail-to-rail common-mode input range including ground. Each channel features ultra-low input bias current (5pA typical) and stable offset voltage (≤5mV at 25°C), enabling direct interface with high-impedance sensors and reference sources.
Its n-channel open-drain outputs support wired-AND logic, level translation up to 16V, and TTL/MOS/CMOS compatibility. The device includes built-in ESD protection rated at 2000V and is characterized across −40°C to +85°C for industrial reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 16V - enables operation from single Li-ion cell (3.0–3.7V) up to 12V industrial rails |
| Input Offset Voltage (max) | 5mV at 25°C - ensures accurate threshold detection with ≤5mV error in precision window-comparator designs |
| Supply Current (typ) | 150µA at 5V - supports multi-year battery life in always-on sensor nodes |
| Input Bias Current (typ) | 5pA - allows direct connection to photodiodes, piezoelectric sensors, and high-value resistor dividers without loading error |
| Common-Mode Input Range | 0V to VDD−1.5V - supports ground-referenced inputs and rail-sensing applications |
| Response Time | 200ns at 100mV overdrive - suitable for medium-speed signal conditioning and overvoltage/undervoltage fault detection |
| ESD Rating | 2000V HBM - meets basic industrial handling requirements without external protection |
Pinout & Package
Package: SOIC-8 (D package), 3.9mm × 4.9mm body, 1.75mm max height, gull-wing leads, RoHS-compliant NIPDAU finish, MSL Level-1.
| 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 ground reference - must be low-impedance return path for both comparators and pull-up networks |
| 5 | IN+ B | Non-inverting input of Comparator B - electrically isolated from Channel A; identical specs |
| 6 | IN− B | Inverting input of Comparator B - supports independent threshold setting per channel |
| 7 | OUT B | Open-drain output of Comparator B - independently controllable; supports wired-AND with OUT A |
| 8 | VDD | Positive supply rail - powers both comparators; accepts 2.7V–16V; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables simultaneous monitoring of two thresholds (e.g., overvoltage + undervoltage) in one SOIC-8 footprint |
| Open-drain outputs | Permits flexible logic-level translation (e.g., 3.3V comparator driving 5V or 12V logic bus) and wired-AND fault aggregation |
| 10¹²Ω input impedance | Eliminates loading on high-Z sources like thermistors, RTDs, and capacitive sensors without buffer amplifiers |
| −40°C to +85°C operation | Validated performance across full industrial temperature range - no derating required for factory automation or outdoor equipment |
| Pin-compatible with LM393 | Allows drop-in replacement in legacy designs while upgrading to lower power, higher input impedance, and wider supply range |
Applications
| Overvoltage Protection Circuit | Battery State-of-Charge Monitor |
|---|---|

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 offset (7mV max), higher supply current (1mA typ), bipolar process, no ESD rating specified | Less accurate thresholding; unsuitable for battery life >1 year; limited to 0°C–70°C | Choose LM393DR only for cost-sensitive commercial designs where 5mV offset and industrial temp are not required. |
| TLC372CDR | Same CMOS architecture, 5mV offset, but only rated for 0°C–70°C; identical pinout and electrical specs otherwise | Not qualified for −40°C operation; unsuitable for outdoor or automotive under-hood use | Select TLC372CDR for commercial-grade applications needing identical performance at lower cost and wider availability. |
Compared with LM393DR and TLC372CDR, the TLC352ID uniquely combines industrial temperature range, 5mV offset, and 150µA supply current in a pin-compatible SOIC-8 package - making it the only option for long-life, wide-temperature, precision dual-comparator applications.

FAQ
What is the maximum supply voltage for the TLC352ID?
The TLC352ID supports a maximum supply voltage of 16V under recommended operating conditions. Absolute maximum rating is 18V, but sustained operation above 16V risks parametric degradation and reduced reliability. This 16V limit enables safe integration into 12V industrial systems with margin for transient spikes.
Does the TLC352ID require external pull-up resistors on its outputs?
Yes, the TLC352ID features open-drain outputs that require external pull-up resistors to establish HIGH logic levels. TI recommends values between 10kΩ and 100kΩ depending on speed and power trade-offs; a 10kΩ resistor yields ~150µA static current per active output at 5V, balancing rise time and quiescent power.
Can the TLC352ID operate from a single 3.3V supply?
Yes, the TLC352ID is fully specified down to 2.7V supply voltage, making it compatible with 3.3V systems. At 3.3V, it maintains 5mV max input offset, 5pA input bias current, and 200ns response time - enabling precision threshold detection in modern low-voltage embedded designs without level-shifting circuitry.
Is the TLC352ID pin-compatible with the LM393?
Yes, the TLC352ID is explicitly designed as a pin-compatible upgrade to the LM393 in SOIC-8 (D) package. Both share identical pin assignments (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD), allowing direct PCB replacement while delivering lower power, higher input impedance, and industrial temperature range.
What is the input common-mode voltage range for the TLC352ID?
The TLC352ID supports a common-mode input voltage range from 0V to VDD−1.5V across its full −40°C to +85°C operating range. This includes ground-referenced inputs and permits direct sensing of signals near the negative rail - critical for battery monitoring and single-supply sensor interfaces.
