Product details
Overview
TLC3702IPWR 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 battery-powered sensor monitoring and precision threshold detection circuits.
For engineers reviewing the TLC3702IPWR datasheet, TLC3702IPWR pinout, TLC3702IPWR application, or TLC3702IPWR equivalent, this device offers verified micropower performance (100 μW typ at 5 V), rail-to-rail input compatibility (0 V to VDD − 1.5 V), TTL- and HCMOS-compatible outputs, and on-chip ESD protection per human-body model (2000 V).
Technical Context
The TLC3702IPWR 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 maintaining fast response and full TTL logic compatibility.
It operates across −40°C to 85°C (industrial grade), supports common-mode input voltages up to VDD − 1.5 V, and features internal ESD protection rated to 2000 V HBM and 200 V CDM - enabling robust use in noisy industrial environments without external clamping.
Key Specifications

| Input Offset Voltage (max) | 7 mV over −40°C to 85°C - ensures reliable threshold detection accuracy in precision analog sensing. |
| Propagation Delay (tPLH) | 2.7 μs typ at 5-mV overdrive - supports sub-400-kHz signal edge detection with predictable timing. |
| Output Drive Capability | ±8 mA - directly drives LEDs, logic inputs, or small capacitive loads (e.g., 50 pF) without external buffers. |
| Quiescent Supply Current | 40 μA typ (both comparators) - enables multi-year battery life in always-on wake-up or low-power monitoring circuits. |
| Input Common-Mode Range | 0 V to VDD − 1.5 V - allows direct sensing of ground-referenced signals and rail-sensing applications. |

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 quiescent current (500 μA vs. 40 μA), open-collector output requiring external pullup, 2 mV higher typical input offset. | Suitable for general-purpose 5 V logic interfacing but not battery-critical or space-constrained designs. | Select LM393DR only if legacy design reuse or cost sensitivity outweighs micropower and push-pull advantages. |
| TLC372CDR | Same LinCMOS™ architecture and pinout, but commercial-grade (0°C to 70°C) and lower ESD rating (1500 V HBM vs. 2000 V). | Acceptable for consumer electronics or lab equipment where extended temperature or ruggedness is not required. | Choose TLC372CDR for cost-sensitive commercial applications; TLC3702IPWR preferred for industrial reliability. |
Compared with LM393DR and TLC372CDR, the TLC3702IPWR delivers 12× lower supply current, eliminates pullup components, and provides verified 2000 V HBM ESD protection - making it optimal for long-life, high-reliability, and space-constrained industrial sensing.

FAQ
What is the maximum operating temperature range for the TLC3702IPWR?
The TLC3702IPWR is specified for operation from −40°C to +85°C, meeting industrial temperature requirements. This range is validated across all key parameters including input offset voltage (7 mV max), supply current (65 μA max), and propagation delay - ensuring consistent performance in factory automation, outdoor metering, and automotive under-hood applications where ambient temperatures fluctuate widely.
Does the TLC3702IPWR require an external pullup resistor on its outputs?
No, the TLC3702IPWR does not require an external pullup resistor because it features a push-pull CMOS output stage. Each output (OUT1 and OUT2) actively drives high or low, delivering ±8 mA sink/source capability. This eliminates the need for external components, reduces board space, lowers system power consumption, and improves rise/fall times - unlike open-collector comparators such as the LM393.
What is the input common-mode voltage range of the TLC3702IPWR?
The TLC3702IPWR supports an input common-mode voltage range of 0 V to VDD − 1.5 V across its full operating temperature range (−40°C to +85°C). At 5 V supply, this means inputs can swing from 0 V to 3.5 V. This rail-to-rail input capability enables direct interfacing with ground-referenced sensors and resistive dividers without level-shifting circuitry - a key advantage over older bipolar comparators.
How does the TLC3702IPWR compare to the LM339 in terms of power consumption?
The TLC3702IPWR consumes approximately one-twentieth the power of the LM339 while delivering comparable response time. At 5 V, TLC3702IPWR draws just 40 μA (100 μW), whereas the LM339 draws ~1.5 mA (7.5 mW). This 12× reduction enables years of operation on coin-cell batteries and makes the TLC3702IPWR ideal for always-on wake-up circuits, portable medical devices, and remote environmental sensors where energy efficiency is critical.
Is the TLC3702IPWR pin-compatible with other TSSOP-8 dual comparators?
Yes, the TLC3702IPWR uses the industry-standard TSSOP-8 pinout (1:OUT1, 2:IN1−, 3:IN1+, 4:GND, 5:VDD, 6:OUT2, 7:IN2−, 8:IN2+), matching TI's TLC372, LM393, and TLV3702 families. This allows drop-in replacement in existing layouts - provided the application tolerates differences in supply current, input offset, and ESD rating. Always verify layout clearance for thermal pad exposure if used in high-reliability designs.
