Product details
Overview
TLC3702CPS 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 TLC3702CPS datasheet, TLC3702CPS pinout, TLC3702CPS application, or TLC3702CPS equivalent, this page delivers verified specifications, commercial-temperature-grade performance data (0°C to 70°C), package-specific terminal mapping for the plastic DIP (P) package, and validated alternative comparators for low-power single-supply designs.
Technical Context
The TLC3702CPS implements two independent comparators on a LinCMOS™ process, enabling rail-to-rail input operation (0 V to VDD − 1.5 V) and TTL/CMOS-compatible push-pull outputs without external pull-up resistors. Its architecture eliminates static current paths in the output stage, directly supporting capacitive loads up to 50 pF while maintaining sub-3-μs response.
Input stage design features ultra-low bias current (5 pA typ at 25°C), high common-mode rejection (84 dB min), and 2-kV HBM ESD protection per I/O pin. The device operates from 3 V to 16 V single supply and is characterized across 0°C to 70°C - matching the TLC3702C temperature grade.
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 logic/system rails without level shifters. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures reliable detection of small analog signals above noise floor in precision threshold applications. |
| Propagation Delay (tPLH) | 2.7 μs typ with 5-mV overdrive - enables fast decision-making in real-time monitoring systems with minimal latency. |
| Supply Current (both channels) | 40 μA max at 25°C - reduces quiescent power by >95% vs. LM339, extending battery life in portable instrumentation. |
| Output Drive Capability | ±8 mA - drives LEDs, logic inputs, or small MOSFET gates directly without external buffers or pull-ups. |
| Input Bias Current | 5 pA typ at 25°C - minimizes loading error on high-impedance sources like thermistors or photodiodes. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows sensing near ground or rail in single-supply systems without input clamping. |
Pinout & Package
Package: Plastic Dual-In-Line (P), 8-pin, through-hole. Pin spacing: 0.3 inch (7.62 mm), body width: 0.35 inch (8.89 mm).
| Pin/Terminal | Circuit Role | Design Meaning |

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 | Higher supply current (500 μA typ), open-collector output requiring pull-up, 2 mV offset (typ), wider temp range (−40°C to 85°C). | Requires external pull-up resistor; less suitable for ultra-low-power battery designs but better for mixed-voltage interfacing. | Select LM393DR when interfacing with 3.3 V logic driving 5 V loads, or where higher speed (1.3 μs tPLH) outweighs power penalty. |
| TLC372CP | Same LinCMOS™ process, identical pinout and specs, but rated for 0°C to 70°C (C grade) - functionally identical to TLC3702CPS except packaging (DIP vs SOIC). | No functional difference; differs only in surface-mount (SOIC-8) vs through-hole (PDIP-8) package form factor. | Select TLC372CP for automated SMT assembly; TLC3702CPS remains optimal for hand-soldered prototypes or legacy through-hole boards. |
Compared with LM393DR and TLC372CP, the TLC3702CPS offers lowest quiescent power (40 μA vs 500 μA) and eliminates pull-up resistors - making it optimal for space-constrained, battery-operated systems where board area and energy efficiency are primary constraints.

FAQ
What is the maximum supply voltage for the TLC3702CPS?
The absolute maximum supply voltage for the TLC3702CPS is 18 V, but the recommended operating range is 3 V to 16 V. Operation at 16 V is fully specified across the 0°C to 70°C temperature range, with parameters including output drive (±8 mA), propagation delay (≤3.5 μs), and input offset voltage (≤6.5 mV) guaranteed per datasheet SLCS013E.
Does the TLC3702CPS require external pull-up resistors on its outputs?
No, the TLC3702CPS does not require external pull-up resistors because it features push-pull CMOS outputs capable of sourcing and sinking up to ±8 mA. This architecture eliminates static current draw and board space associated with pull-up resistors - a key differentiator from open-collector comparators like the LM393.
What is the input offset voltage specification for the TLC3702CPS over temperature?
The TLC3702CPS has a maximum input offset voltage of 5 mV at 25°C and 6.5 mV across the full commercial temperature range (0°C to 70°C). This value is measured under standard test conditions (VDD = 5 V, VIC = VICRmin) and reflects worst-case performance for precision threshold applications.
Can the TLC3702CPS drive a 50-pF capacitive load while maintaining its specified propagation delay?
Yes, the TLC3702CPS is characterized for 50-pF capacitive loads in its switching characteristics table: tPLH = 2.7 μs typ and tPHL = 2.3 μs typ at VDD = 5 V, TA = 25°C, with 5-mV overdrive. The push-pull output stage ensures stable timing without external compensation, unlike open-collector comparators that degrade with capacitance.
Is the TLC3702CPS pin-compatible with the LM339?
No, the TLC3702CPS is not pin-compatible with the LM339. While both are dual comparators, the LM339 uses open-collector outputs and a different pinout (e.g., LM339 pins 1/2/3 = OUT1/IN1−/IN1+, whereas TLC3702CPS pins 1/2/3 = OUT1/IN1−/IN1+ - same order but incompatible output structure). Direct replacement requires circuit redesign to remove pull-up resistors and verify voltage compatibility.
