Product details
Overview
TLC3702IPG4 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, ±8 mA output drive capability, and 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive - designed for single-supply operation from 3 V to 16 V in industrial sensor interface and battery-powered monitoring circuits.
For engineers reviewing the TLC3702IPG4 datasheet, TLC3702IPG4 pinout, TLC3702IPG4 application, or TLC3702IPG4 equivalent, this device offers verified micropower performance (18–65 μA supply current), rail-to-rail input compatibility (0 V to VDD − 1.5 V), TTL/CMOS-compatible push-pull outputs, and on-chip ESD protection per HBM 2 kV - critical for low-noise threshold detection in harsh environments.
Technical Context
The TLC3702IPG4 integrates two independent comparators fabricated using Texas Instruments' LinCMOS™ process, delivering high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage across temperature (7 mV max over −40°C to +85°C). Its differential input stage supports common-mode voltages up to VDD − 1.5 V.
The push-pull output stage eliminates external pullup resistors, enabling direct capacitive load driving (CL = 50 pF) while maintaining fast response (tPHL = 2.3 μs typ) and full TTL logic compatibility - unlike open-drain comparators requiring external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct integration into 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Input Offset Voltage (max) | 7 mV over −40°C to +85°C - ensures reliable threshold detection accuracy in industrial temperature ranges. |
| Propagation Delay (tPLH) | 2.7 μs typ @ 5-mV overdrive, CL = 50 pF - supports medium-speed window/zero-crossing detection in motor control feedback. |
| Supply Current (both channels) | 65 μA max over −40°C to +85°C - enables multi-year operation on coin-cell batteries in wireless sensor nodes. |
| Output Drive Capability | ±8 mA sink/source - directly interfaces with LED indicators, logic gates, or small MOSFET gate drivers without buffering. |
| Input Common-Mode Range | 0 V to VDD − 1.5 V - allows sensing signals near ground or rail in single-supply data acquisition front-ends. |
| ESD Protection | 2 kV HBM - meets IEC 61000-4-2 Level 2 requirements for robustness during board handling and field deployment. |
Pinout & Package
Package: 8-pin PDIP (Plastic Dual In-line Package), body width 0.300 inch (P-G8), lead finish matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull CMOS output of comparator 1 - drives high/low actively; no external pullup required. |
| 2 | 1IN− | Inverting input of comparator 1 - accepts reference or feedback signal for threshold comparison. |
| 3 | 1IN+ | Non-inverting input of comparator 1 - connects to sensed analog signal (e.g., battery voltage, temperature sensor output). |
| 4 | GND | Analog/digital ground reference - must be low-impedance return path for both comparators and output loads. |
| 5 | VDD | Positive supply rail - powers both comparators and output stages; decoupling capacitor (0.1 μF) required at pin. |
| 6 | 2OUT | Push-pull CMOS output of comparator 2 - independently controllable; shares same VDD/GND rails. |
| 7 | 2IN− | Inverting input of comparator 2 - used for second independent threshold decision (e.g., overvoltage/undervoltage window). |
| 8 | 2IN+ | Non-inverting input of comparator 2 - connects to secondary analog signal path or inverted reference. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 18–65 μA total supply current - reduces thermal load and extends battery life in portable instrumentation. |
| Rail-to-Rail Input Capability | 0 V to VDD − 1.5 V common-mode range - enables direct sensing of signals near ground or supply rails without resistor dividers. |
| Push-Pull Output Stage | No external pullup resistor needed - saves PCB area, BOM cost, and eliminates resistor-induced delay/noise in timing-critical paths. |
| LinCMOS™ Process Technology | Input bias current ≤5 pA (25°C), offset drift <1 μV/°C - delivers precision stability in high-impedance sensor interfaces (e.g., pH, photodiode). |
| Industrial Temperature Rating | −40°C to +85°C operating range - qualified for use in factory automation, HVAC controls, and outdoor metering equipment. |
Applications
| Battery Voltage Monitor | Motor Overcurrent Detection |
|---|---|
|

IC Role / Device Role / Timing Role: TLC3702IPG4 compares amplified shunt voltage against programmable thresholds to trigger fault shutdown. Use Value: 2.7 μs propagation delay enables sub-millisecond response; rail-to-rail inputs accommodate 0–5 V sense range without attenuation. |
| Temperature Threshold Alarm | Power Supply Sequencing |
|
Use Scenario: Activating cooling fan when ambient temperature exceeds 70°C in telecom power supplies. IC Role / Device Role / Timing Role: Dual comparator implements hysteresis via feedback resistors on IN+ pins to prevent chatter near trip point. Use Value: 7 mV max input offset ensures accurate 70°C setpoint; LinCMOS™ input stability prevents drift over 10+ year deployments. |
Use Scenario: Verifying proper ramp-up order of 1.2 V, 3.3 V, and 5 V rails in FPGA-based systems. IC Role / Device Role / Timing Role: Each comparator monitors one supply rail against its reference; outputs feed AND gate to enable system reset. Use Value: Single 5 V supply powers all three comparators; push-pull outputs eliminate need for discrete logic-level translators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-drain output, higher supply current (500 μA), 2 mV offset (typ), no ESD rating specified | Requires external pullup; unsuitable for direct TTL interfacing or low-power battery systems | Select LM393DR only if cost is primary constraint and pullup resistors are acceptable in layout. |
| TLV3702IDR | Lower supply current (1.6 μA), rail-to-rail input/output, but limited 5.5 V max VDD and −40°C to +125°C rating | Better for ultra-low-power designs below 5.5 V; not compatible with 12 V or 16 V supplies | Choose TLV3702IDR when operating at ≤5.5 V and sub-μA quiescent current is mandatory. |
Compared with LM393DR and TLV3702IDR, the TLC3702IPG4 uniquely balances industrial temperature range (−40°C to +85°C), 3–16 V supply flexibility, push-pull drive, and verified 7 mV offset - making it optimal for legacy industrial systems requiring drop-in reliability without redesign.

FAQ
What is the maximum supply voltage for the TLC3702IPG4?
The TLC3702IPG4 supports a maximum supply voltage of 16 V, with absolute maximum rating at 18 V. It operates reliably across the full recommended range of 3 V to 16 V, making it compatible with 3.3 V, 5 V, 12 V, and 15 V systems without external regulation. This wide range simplifies design in mixed-voltage industrial equipment where multiple rails coexist.
Does the TLC3702IPG4 require external pullup resistors on its outputs?
No, the TLC3702IPG4 does not require external pullup resistors because it features a push-pull CMOS output stage capable of sourcing and sinking up to ±8 mA. This architecture directly drives TTL and CMOS logic inputs, LEDs, or small MOSFET gates - eliminating board space, BOM cost, and timing uncertainty associated with pullup networks.
What is the input offset voltage specification for the TLC3702IPG4 over temperature?
The TLC3702IPG4 has a maximum input offset voltage of 7 mV over the full industrial temperature range of −40°C to +85°C. At 25°C, the typical value is 1.2 mV, with a maximum of 5 mV. This tight offset ensures consistent threshold accuracy in temperature-variable environments like factory floors or outdoor enclosures.
Can the TLC3702IPG4 operate from a 3.3 V supply?
Yes, the TLC3702IPG4 is fully specified to operate from a 3.3 V supply. Its minimum supply voltage is 3 V, and all key parameters - including propagation delay (2.7 μs typ), output drive (±8 mA), and input common-mode range (0 V to VDD − 1.5 V) - are guaranteed at 3.3 V. This makes it ideal for modern low-voltage embedded systems.
Is the TLC3702IPG4 pin-compatible with the LM339?
No, the TLC3702IPG4 is not pin-compatible with the LM339. While functionally similar as a dual comparator, the TLC3702IPG4 uses an 8-pin PDIP package with dedicated VDD and GND pins and push-pull outputs, whereas the LM339 uses a 14-pin package with open-drain outputs and shared power pins. Board redesign is required for substitution.
