Product details
Overview
TLC3702CP from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, 100 μW typical supply power at 5 V, and 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive - used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLC3702CP datasheet, TLC3702CP pinout, TLC3702CP application, or TLC3702CP equivalent, this page delivers verified electrical specs, industrial-temperature operation (−40°C to +85°C), DIP-8 package mapping, real-world use cases, and two validated alternative comparators for low-power, single-supply designs.
Technical Context
The TLC3702CP uses Texas Instruments' LinCMOS™ process to achieve 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 push-pull output stage eliminates external pull-up resistors while delivering ±20 mA drive capability and full TTL compatibility.
It operates from a single 3 V to 16 V supply, supports rail-to-rail common-mode input range (0 V to VDD − 1.5 V), and integrates on-chip ESD protection rated to 2 kV HBM - enabling robust performance in noisy industrial environments without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct interface with Li-ion, 5 V, and 12 V systems without regulation. |
| Input Offset Voltage (max) | 7 mV over −40°C to +85°C - ensures reliable threshold detection in temperature-varying sensor interfaces. |
| Supply Current (both comparators) | 65 μA max over −40°C to +85°C - supports multi-year battery life in always-on monitoring applications. |
| Propagation Delay (tPLH) | 2.3 μs typ at 5-mV overdrive, 5 V supply - provides fast response for pulse-width or zero-crossing detection. |
| Output Drive | ±20 mA sink/source - directly drives LEDs, logic inputs, or small MOSFET gates without external buffers. |
| Input Bias Current | 0.6 nA max at +85°C - preserves accuracy in high-impedance voltage divider or photodiode sensing networks. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows direct sensing of signals referenced to ground or near-rail voltages. |
Pinout & Package
TL3702CP is supplied in an 8-pin plastic DIP (P) package with 0.3-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise from top-left when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull CMOS output of comparator 1 - sinks or sources up to 20 mA, no pull-up required. |
| 2 | IN1− | Inverting input of comparator 1 - high-impedance node (5 pA bias current) for precision reference comparison. |
| 3 | IN1+ | Non-inverting input of comparator 1 - accepts signals from 0 V to VDD − 1.5 V without phase inversion. |
| 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 required at pin. |
| 6 | OUT2 | Push-pull CMOS output of comparator 2 - independent, identical drive capability to OUT1. |
| 7 | IN2− | Inverting input of comparator 2 - electrically isolated from IN1−; supports dual independent thresholds. |
| 8 | IN2+ | Non-inverting input of comparator 2 - enables simultaneous monitoring of two distinct analog conditions. |
Key Features

Applications
| Battery-Powered Threshold Detection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Monitoring battery voltage against low-charge cutoff and overvoltage limits in handheld medical devices. IC Role / Device Role / Timing Role: Dual comparator independently compares battery voltage to two precision references (e.g., 3.0 V and 4.2 V). Use Value: 65 μA supply current enables >5-year shelf life; push-pull outputs directly drive MCU wake-up interrupt lines. |
Use Scenario: Converting thermistor or RTD bridge outputs into clean digital alerts for PLC input modules. IC Role / Device Role / Timing Role: Compares conditioned analog sensor voltage against programmable high/low trip points. Use Value: 7 mV max input offset ensures <±0.5°C error in temperature alarms; −40°C to +85°C rating suits factory-floor deployment. |
| Power Supply Sequencing Control | Zero-Crossing Detection for AC Line Monitoring |
Use Scenario: Validating correct startup order of multiple DC rails (e.g., 3.3 V before 1.2 V) in FPGA-based systems. IC Role / Device Role / Timing Role: Each comparator monitors one rail and asserts enable signals only when voltage exceeds threshold. Use Value: Rail-to-rail input range accepts direct connection to unregulated supplies; 2.3 μs response prevents false sequencing faults. |
Use Scenario: Detecting AC line zero crossings in smart energy meters using a resistively scaled waveform. IC Role / Device Role / Timing Role: Compares scaled AC signal to ground reference to generate precise timing edges. Use Value: 5-mV offset tolerance minimizes phase error (<0.1° at 50 Hz); TTL-compatible output drives microcontroller capture timers directly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393IP | Higher supply current (500 μA typ), open-collector output requiring pull-up, 2 mV offset (typ) but wider temp range (−40°C to +85°C). | Requires external pull-up; less suitable for ultra-low-power or space-constrained designs. | Select LM393IP only if legacy design reuse or cost sensitivity outweighs power and layout advantages of TLC3702CP. |
| TLV3702IP | Lower supply current (35 μA typ), rail-to-rail input, same push-pull output, but narrower supply range (2.7 V to 16 V) and 3.5 mV offset (max). | Better for sub-3 V battery systems; improved input range enables direct sensing of low-voltage sensors. | Choose TLV3702IP for new designs targeting <3 V operation or tighter offset requirements; TLC3702CP remains optimal for 3–5 V industrial systems. |
Compared with LM393IP and TLV3702IP, the TLC3702CP offers the best balance of industrial temperature rating, proven reliability in DIP-8 packaging, and micropower performance without sacrificing output drive strength - making it ideal for long-lifecycle embedded control applications where layout simplicity and thermal stability are critical.

FAQ
What is the operating temperature range of the TLC3702CP?
The TLC3702CP is characterized for operation from −40°C to +85°C, meeting industrial temperature requirements. This range is explicitly defined in the "AVAILABLE OPTIONS" table and confirmed in the "recommended operating conditions" section for the TLC3702I grade, which corresponds to the 'P' suffix package variant. The device maintains specified performance-including 7 mV max input offset voltage and 65 μA max supply current-across this full range.
Does the TLC3702CP require external pull-up resistors on its outputs?
No, the TLC3702CP does not require external pull-up resistors. Its push-pull CMOS output stage actively drives both high and low states, delivering ±20 mA output current. This architecture eliminates the need for pull-up resistors, reducing power dissipation, saving board space, and avoiding resistor-induced delays - a key differentiator from open-collector comparators like the LM393.
What is the maximum input offset voltage specification for the TLC3702CP over temperature?
The maximum input offset voltage for the TLC3702CP is 7 mV over the full operating temperature range of −40°C to +85°C. This value is specified in the "electrical characteristics" table for the TLC3702I grade under "Input offset voltage" with test condition VIC = VICRmin, and applies directly to the P-package industrial variant.
Can the TLC3702CP operate from a 3 V supply?
Yes, the TLC3702CP supports a minimum supply voltage of 3 V, as stated in the "recommended operating conditions" for the TLC3702I grade. At 3 V, it maintains functional performance including rail-to-rail input range (0 V to VDD − 1.5 V = 1.5 V), valid output swing, and specified propagation delay - making it suitable for single-cell Li-ion or 3.3 V system integration.
How is ESD protection implemented in the TLC3702CP?
The TLC3702CP integrates Texas Instruments' patented on-chip ESD-protection circuitry on all pins, qualified to 2 kV per the Human Body Model (100 pF / 1500 Ω). This protection uses a combination of bipolar transistors (Q1, Q2) and zener diodes (D1–D3) to safely shunt positive and negative transients while minimizing post-ESD leakage - eliminating the need for external TVS diodes in most board-level applications.
