Product details
Overview
TLC3702CPW from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV input offset voltage max at 25°C, 2.7-μs typical propagation delay (tPLH) at 5-mV overdrive, and single-supply operation from 3 V to 16 V. It drives capacitive loads directly without external pullup resistors and is used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLC3702CPW datasheet, TLC3702CPW pinout, TLC3702CPW application, or TLC3702CPW equivalent, key selection criteria include micropower consumption (40 μA max IDD), rail-to-rail input common-mode range (0 V to VDD − 1.5 V), push-pull output drive capability (±8 mA), and industrial-grade temperature rating (−40°C to 85°C).
Technical Context
The TLC3702CPW 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 push-pull output stage eliminates external pullup components while maintaining TTL-compatible logic levels.
This device replaces legacy bipolar comparators like LM339 in low-power applications, achieving comparable speed (2.3–4.5 μs tPHL/tPLH) at 1/20th the supply current. Input protection includes on-chip ESD structures rated to 2 kV HBM and 200 V CDM, with internal current limiting for inputs exceeding VICR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - supports direct interface with 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 switching accuracy in precision threshold detection. |
| Propagation Delay (tPLH/tPHL) | 2.3 μs / 1.5 μs typ at 5-mV overdrive, CL = 50 pF - enables fast response in timing-critical window comparators. |
| Supply Current (IDD) | 65 μA max over full temperature range - enables multi-year operation in coin-cell–powered IoT sensors. |
| Output Drive Capability | ±8 mA push-pull - directly drives LEDs, MOSFET gates, or logic inputs without external buffers or pullups. |
| Input Common-Mode Range | 0 V to VDD − 1.5 V - allows sensing near ground or rail in single-supply systems. |
| ESD Rating | 2000 V HBM, 200 V CDM - meets industrial handling requirements without additional board-level protection. |
Pinout & Package
TLC3702CPW is packaged in a 8-pin TSSOP (PW) with exposed thermal pad. Pin functions are identical to the P/D-package variants per TI SLCS013E datasheet Figure 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull CMOS output of comparator 1 - sinks or sources up to ±8 mA, no pullup 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 - shared return path for both comparators and output loads. |
| 5 | VDD | Positive supply rail - powers both comparators and output stages; decoupling capacitor required. |
| 6 | OUT2 | Push-pull CMOS output of comparator 2 - electrically isolated from OUT1, supports independent load control. |
| 7 | IN2− | Inverting input of comparator 2 - fully independent channel with same electrical specs as IN1−. |
| 8 | IN2+ | Non-inverting input of comparator 2 - enables dual-threshold or window-comparator topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 40 μA typical supply current per comparator - reduces system standby power by >95% vs LM339. |
| Push-Pull Output Stage | No external pullup resistor needed - saves PCB area, BOM cost, and eliminates pullup-induced delay uncertainty. |
| LinCMOS™ Process Technology | Input bias current <5 pA at 25°C and <2 nA at 85°C - enables high-impedance sensor interfacing without signal loading. |
| Rail-to-Rail Input Range | Common-mode voltage extends to GND and within 1.5 V of VDD - supports direct connection to transducer outputs. |
| Industrial Temperature Range | Specified from −40°C to +85°C - qualified for use in automotive cabin modules, industrial PLC I/O, and outdoor sensors. |

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 | Open-collector output, higher supply current (500 μA typ), wider VIO range (7 mV max at 25°C but unguaranteed over temp) | Requires external pullup; less suitable for low-power or capacitive-load driving | Select LM393DR only if open-collector interface is mandatory and power budget allows ≥10× higher IDD. |
| TLV3702IDR | Lower VIO (3 mV max), lower IDD (25 μA max), same PW package, but narrower supply range (2.7 V to 16 V) | Better precision and efficiency, but not rated for 3-V minimum operation | Choose TLV3702IDR where tighter offset and lower power are critical and 3-V operation is not required. |
Compared with LM393DR and TLV3702IDR, the TLC3702CPW uniquely balances industrial temperature rating, push-pull drive, and 3-V compatibility-making it optimal for legacy 3.3-V/5-V systems needing robust, low-component-count threshold detection.

FAQ
What is the maximum supply voltage for the TLC3702CPW?
The TLC3702CPW has an absolute maximum supply voltage of 18 V, but its recommended operating range is 3 V to 16 V. Operation above 16 V risks violating recommended conditions and may impact long-term reliability, even if within absolute ratings. The TLC3702CPW maintains specified performance-including 7 mV max input offset and 65 μA max IDD-only within the 3–16 V range.
Does the TLC3702CPW require external pullup resistors on its outputs?
No, the TLC3702CPW 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 eliminates the need for pullup resistors, reducing board space, BOM cost, and propagation delay uncertainty-unlike open-collector comparators such as the LM393. The TLC3702CPW achieves this while remaining fully compatible with TTL logic thresholds.
What is the input common-mode voltage range of the TLC3702CPW?
The TLC3702CPW supports an input common-mode voltage range of 0 V to VDD − 1.5 V over its full operating temperature range (−40°C to 85°C). At 25°C, the range extends to 0 V to VDD − 1 V. This rail-to-rail capable input allows direct interfacing with ground-referenced sensors and low-voltage references without level-shifting circuitry-enabling simpler, more accurate designs using the TLC3702CPW.
How does the TLC3702CPW compare to the LM339 in power consumption?
The TLC3702CPW consumes approximately 1/20th the supply current of the LM339 while delivering comparable response times. At 5 V, the TLC3702CPW draws just 40 μA typical (65 μA max over temperature), versus ~800 μA for the LM339. This dramatic reduction enables years of operation in battery-powered applications and eliminates thermal concerns in dense layouts-making the TLC3702CPW a direct, drop-in upgrade for LM339-based designs where power is constrained.
Is the TLC3702CPW pin-compatible with other packages in the TLC3702 family?
Yes, the TLC3702CPW (TSSOP-8) shares identical pinout and electrical functionality with the TLC3702CD (SOIC-8) and TLC3702CP (PDIP-8), as confirmed by TI SLCS013E datasheet Figures 1 and 2. All three packages route OUT1, IN1−, IN1+, GND, VDD, OUT2, IN2−, and IN2+ to the same positions. This allows seamless migration between packages during prototyping, qualification, or cost optimization-without PCB redesign-while retaining full compatibility with the TLC3702CPW's specifications.
