Product details
Overview
TLC393IPG4 from Texas Instruments is a dual micropower voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 3 V to 16 V. It delivers 110 µW typical supply power at 5 V, 2.5 µs typical propagation delay (tPLH) with 5-mV overdrive, and 5 mV max input offset voltage at 25°C - enabling precision threshold detection in battery-powered industrial sensors and power-supply supervisors.
For engineers reviewing the TLC393IPG4 datasheet, TLC393IPG4 pinout, TLC393IPG4 application, or TLC393IPG4 equivalent, this page provides verified package mapping (8-pin PDIP), confirmed LinCMOS™ process advantages (low bias current, high CMRR), temperature-rated performance (−40°C to 85°C), and real-world design context for low-power analog signal conditioning.
Technical Context
The TLC393IPG4 implements two independent comparators using Texas Instruments' LinCMOS™ process, delivering ultra-low input bias current (≤5 pA at 25°C) and stable input offset voltage (≤7 mV across −40°C to 85°C). Its open-drain output stage requires external pull-up and supports interfacing with TTL, CMOS, or mixed-voltage logic loads.
It operates with common-mode input range from −0.2 V to VDD − 1.5 V, achieves 84 dB minimum common-mode rejection ratio (CMMR), and maintains 85 dB supply-voltage rejection ratio (kSVR) - ensuring robust performance in noisy industrial environments where rail-to-rail input swing and supply ripple immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - supports wide-input industrial rails and battery-backed systems without level-shifting. |
| Quiescent Supply Current | 22–65 µA (both comparators, −40°C to 85°C) - enables multi-year operation on coin-cell batteries. |
| Input Offset Voltage | ≤7 mV (−40°C to 85°C) - ensures reliable 10-mV-level threshold detection without calibration. |
| Propagation Delay (tPLH) | 2.5 µs typ @ 5-mV overdrive, VDD = 5 V - suitable for medium-speed monitoring (e.g., power-fail detection & motor control). |
| Input Bias Current | ≤2 nA (85°C) - minimizes error in high-impedance sensor interfaces (e.g., thermistors, photodiodes). |
| Common-Mode Input Range | −0.2 V to VDD − 1.5 V - allows direct sensing of signals near ground or rail without clamping diodes. |
| Output Type | Open-drain CMOS - enables wired-OR logic, level translation, and flexible pull-up to any compatible voltage (≤16 V). |
Pinout & Package
Package: 8-pin plastic DIP (PDIP), body width 0.300 inch (PG-8), JEDEC MS-001AC. RoHS-compliant, lead-finish NIPDAU, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain output of Comparator 1 - requires external pull-up; sinks up to 20 mA. |
| 2 | IN1− | Inverting input of Comparator 1 - accepts voltages from −0.2 V to VDD − 1.5 V. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - same common-mode range as IN1−. |
| 4 | GND | Ground reference for both comparators and internal circuitry - must be low-impedance. |
| 5 | VDD | Positive supply rail - powers both comparators; decoupling capacitor (0.1 µF) required at pin. |
| 6 | OUT2 | Open-drain output of Comparator 2 - electrically isolated from OUT1; shares same VDD/GND. |
| 7 | IN2− | Inverting input of Comparator 2 - fully independent; no crosstalk with Comparator 1. |
| 8 | IN2+ | Non-inverting input of Comparator 2 - supports differential or single-ended configurations. |
Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ Process Technology | Delivers picoampere-level input bias current and stable offset voltage under differential stress - eliminates drift-induced false triggers in long-duration monitoring. |
| Dual Independent Comparators | Enables simultaneous monitoring of two thresholds (e.g., overvoltage + undervoltage) without inter-channel coupling or timing skew. |
| Single-Supply Operation | Eliminates need for split supplies in portable or isolated systems - simplifies PCB layout and reduces BOM count. |
| On-Chip ESD Protection | Withstands ≥2000 V HBM per MIL-STD-883C Method 3015.2 - reduces field failure risk during handling and system integration. |
| Wide Temperature Range | Rated for −40°C to 85°C operation - validated for use in industrial control cabinets, automotive under-hood modules, and outdoor equipment. |
Applications

Use Value: 5 mV offset tolerance ensures accurate 5% voltage margin detection; rail-to-rail input range accommodates unregulated inputs; low IDD avoids loading sensitive reference circuits. |
| Two-Phase Clock Generation | Industrial Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher quiescent current (500 µA typ), wider offset (7 mV max), same SOIC-8 package but not temperature rated beyond 70°C. | Suitable for commercial-grade cost-sensitive designs; lacks extended temperature validation and LinCMOS™ low-bias advantage. | Select LM393DR only when budget constraints outweigh precision and low-power requirements. |
| TLC3702CDR | Push-pull outputs (no external pull-up needed), higher supply current (120 µA), same LinCMOS™ process and −40°C to 85°C rating. | Better for driving capacitive loads directly or interfacing with CMOS logic; unsuitable where wired-OR or level translation is required. | Choose TLC3702CDR when output drive simplicity is prioritized over flexibility and ultra-low power. |
Compared with LM393DR and TLC3702CDR, the TLC393IPG4 uniquely balances micropower consumption (22–65 µA), industrial temperature rating, and open-drain versatility - making it optimal for battery-operated or noise-immune dual-threshold systems where layout flexibility and long-term stability are essential.

FAQ
What is the operating temperature range of the TLC393IPG4?
The TLC393IPG4 is characterized for operation from −40°C to +85°C, meeting industrial-grade environmental requirements. This range is explicitly specified in the "recommended operating conditions" table for the TLC393I variant, which corresponds to the 'I' suffix in TLC393IPG4. Performance parameters including input offset voltage (≤7 mV), supply current (≤65 µA), and propagation delay remain guaranteed across this full span.
Does the TLC393IPG4 require external pull-up resistors on its outputs?
Yes, the TLC393IPG4 features open-drain CMOS outputs (OUT1 and OUT2), which necessitate external pull-up resistors to define the high logic level. The datasheet specifies a recommended 5.1 kΩ pull-up to VDD for standard test conditions. Pull-up voltage may differ from VDD (e.g., 3.3 V logic interfacing with 5 V supply), enabling level translation - a key design advantage confirmed in the "output voltage range" specification (−0.3 V to 16 V).
How does the LinCMOS™ process benefit the TLC393IPG4 in sensor applications?
The LinCMOS™ process gives the TLC393IPG4 ultra-low input bias current (≤5 pA at 25°C, ≤2 nA at 85°C) and exceptional input offset voltage stability (≤7 mV over −40°C to 85°C). In sensor interfaces - such as thermistor or bridge-based measurements - this minimizes measurement error caused by leakage paths and thermal drift, eliminating the need for frequent recalibration in field-deployed equipment.
Can the TLC393IPG4 operate from a 3-V supply?
Yes, the TLC393IPG4 supports a minimum supply voltage of 3 V, as stated in the "recommended operating conditions" for the TLC393I variant. At 3 V, it maintains functional performance: input common-mode range extends down to −0.2 V, propagation delay increases modestly (tPLH ≈ 3.5 µs typ at 5-mV overdrive), and quiescent current remains below 65 µA - making it viable for single-cell Li-ion or 3.3-V systems with tight power budgets.
Is the TLC393IPG4 pin-compatible with the LM393?
No, the TLC393IPG4 is not pin-compatible with the LM393 in PDIP packages. While both are dual comparators in 8-pin DIP, the LM393 uses pinout: 1=OUT1, 2=IN1−, 3=IN1+, 4=GND, 5=IN2+, 6=IN2−, 7=OUT2, 8=VCC. The TLC393IPG4 uses: 1=OUT1, 2=IN1−, 3=IN1+, 4=GND, 5=VDD, 6=OUT2, 7=IN2−, 8=IN2+. This inversion of VDD/OUT2/IN2 pins prevents direct replacement without PCB modification.
