Product details
Overview
TLC3702IPE4 from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at −40°C to 85°C, 2.7 μs typical propagation delay (tPLH) at 5-mV overdrive, ±8 mA output drive, and single-supply operation from 3 V to 16 V. It replaces LM339 in low-power industrial sensing and battery-powered threshold detection circuits.
For engineers reviewing the TLC3702IPE4 datasheet, TLC3702IPE4 pinout, TLC3702IPE4 application, or TLC3702IPE4 equivalent, this page delivers verified electrical specs, industrial-temperature validated performance, package-specific terminal mapping, and real-world comparator selection guidance - all grounded in TI's SLCS013E production data sheet.
Technical Context
The TLC3702IPE4 implements two independent comparators 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 push-pull output stage eliminates external pullup resistors while sustaining 2.7 μs response time into 50-pF loads.
This architecture enables direct interface with HCMOS and TTL logic without level-shifting or external components. On-chip ESD protection meets 2-kV HBM and 200-V CDM standards, and absolute input voltage range extends to ±18 V differential and −0.3 V to VDD for robust signal conditioning in noisy environments.

Applications
| Overvoltage Protection Circuit | Battery Charge Threshold Monitor |
|---|---|
Use Scenario: Detects when input voltage exceeds safe limit (e.g., 12.6 V for Li-ion) to disable charging path via MOSFET gate control. IC Role / Device Role / Timing Role: Dual comparator configures as window detector - one channel monitors upper threshold, second verifies lower bound. Use Value: 7 mV max offset ensures ≤15 mV total threshold error; 2.7 μs response enables sub-millisecond fault shutdown before damage occurs. |
Use Scenario: Monitors cell voltage during constant-current charging to trigger transition to constant-voltage phase at 4.2 V. IC Role / Device Role / Timing Role: Single comparator compares sensed voltage against precision reference; output drives charge controller enable pin. Use Value: 40 μA quiescent current extends runtime of portable test equipment; rail-to-rail input accommodates 0–5 V reference scaling. |
| Industrial Temperature Sensor Interface | Power Supply Sequencing Controller |
Use Scenario: Converts RTD or thermistor resistance changes into digital logic levels for microcontroller ADC input or alarm assertion. IC Role / Device Role / Timing Role: Comparator compares conditioned sensor voltage against fixed or programmable thresholds - operates across full −40°C to 85°C ambient. Use Value: 5 pA input bias prevents loading of high-Z sensor bridges; 84 dB CMRR rejects common-mode noise from 4–20 mA loop transmitters. |
Use Scenario: Ensures proper power-up order of multiple rails (e.g., 5 V before 3.3 V) in FPGA or DSP systems by enabling downstream regulators only after upstream stabilization. IC Role / Device Role / Timing Role: Each comparator independently validates individual rail voltage; outputs feed AND gate or microcontroller GPIO. Use Value: 3 V to 16 V supply range covers all standard logic rails; ±8 mA drive directly controls enable pins of DC/DC converters without buffer stages. |
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 | Higher supply current (500 μA vs 40 μA), wider offset (7 mV vs 7 mV), open-collector output requiring pullup | Lacks push-pull drive; unsuitable for direct TTL/HCMOS interfacing without external resistor | Select when legacy footprint compatibility is required and power budget permits higher consumption |
| TLC372CDR | Same LinCMOS™ process, commercial temp range (0°C to 70°C), identical electrical specs except temperature grading | Not qualified for industrial environments; may exhibit parametric shift outside 0–70°C | Choose for cost-sensitive consumer applications where extended temperature operation is unnecessary |
Compared with LM393DR and TLC372CDR, the TLC3702IPE4 uniquely combines industrial temperature qualification, micropower operation, and resistorless push-pull outputs - making it the only option among the three that satisfies simultaneous requirements for low-power, wide-temperature, and direct-logic-drive applications.

FAQ
What is the maximum input voltage range for TLC3702IPE4?
The TLC3702IPE4 supports a differential input voltage of ±18 V and a common-mode input range of −0.3 V to VDD − 1.5 V. This allows safe operation with inputs exceeding the supply rail (e.g., 18 V input on 5 V supply) when externally current-limited to ±5 mA, as specified in the absolute maximum ratings table of the SLCS013E datasheet. The TLC3702IPE4 maintains functionality under these conditions due to integrated input protection circuitry.
Does TLC3702IPE4 require external pullup resistors on its outputs?
No, the TLC3702IPE4 does not require external pullup resistors. Its push-pull CMOS output stage actively drives both high and low states, delivering ±8 mA output current. This architecture eliminates the need for external pullups while maintaining 2.7 μs typical propagation delay into 50-pF loads - a key differentiator from open-collector comparators like the LM393. The TLC3702IPE4 output is fully compatible with TTL and HCMOS logic families without additional components.
What is the input offset voltage specification for TLC3702IPE4 over temperature?
The TLC3702IPE4 has a maximum input offset voltage of 7 mV across the full industrial operating temperature range of −40°C to 85°C, as confirmed in the "electrical characteristics" table for the TLC3702I variant in the SLCS013E datasheet. At 25°C, the typical value is 1.2 mV, with a maximum of 5 mV. This tight offset ensures accurate threshold detection in precision sensing applications where ambient temperature variation cannot be ignored.
Can TLC3702IPE4 operate from a 3-V supply?
Yes, the TLC3702IPE4 is fully specified to operate from a minimum supply voltage of 3 V, with guaranteed performance including 2.7 μs propagation delay, 7 mV max offset, and ±8 mA output drive. Its LinCMOS™ process enables stable operation at low voltages while retaining high input impedance and low bias current - making the TLC3702IPE4 suitable for coin-cell or single-LiFePO4 powered systems where headroom is constrained.
How does the ESD protection on TLC3702IPE4 compare to standard CMOS comparators?
The TLC3702IPE4 integrates Texas Instruments' patented ESD-protection circuitry, qualified to 2-kV HBM (100-pF/1.5-kΩ) and 200-V CDM (100-pF, no series resistor). Unlike basic diode-clamp protection, this design minimizes post-ESD leakage currents (critical for picoamp-level input bias), preserving accuracy in high-impedance applications. The TLC3702IPE4's protection is built into every input and output pin and is validated per JEDEC standards - a key reliability advantage over generic CMOS comparators.
