Product details
Overview
TLC3702CPSRG4 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 low-to-high propagation delay with 5-mV overdrive - used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLC3702CPSRG4 datasheet, TLC3702CPSRG4 pinout, TLC3702CPSRG4 application, or TLC3702CPSRG4 equivalent, this page delivers verified electrical specs, commercial-temperature (0°C to 70°C) performance data, SOIC-8 package details, and direct functional alternatives for low-power analog signal conditioning designs.
Technical Context
The TLC3702CPSRG4 integrates two independent comparators on a single LinCMOS™ die, each featuring rail-to-rail input common-mode range (0 V to VDD − 1.5 V), TTL-compatible push-pull output stage (±8 mA drive), and on-chip ESD protection rated to 2 kV HBM. Its architecture eliminates external pullup resistors while maintaining fast response under capacitive loads up to 50 pF.
Designed for single-supply operation from 3 V to 16 V, it achieves 84 dB typical CMRR and 85 dB kSVR across temperature, with input bias current as low as 5 pA at 25°C and <1 nA at 70°C - enabling high-impedance sensing without loading source signals.
Key Specifications

Use Value: 50 μA quiescent current extends operational life by >20% versus LM339-based solutions in always-on monitoring. |
Use Scenario: Converting analog output of an NTC thermistor into digital ON/OFF signal for HVAC fan control. IC Role / Device Role / Timing Role: Comparator 2 compares thermistor voltage against fixed reference; hysteresis added via feedback resistor to prevent chatter near trip point. Use Value: 6.5 mV offset tolerance ensures ±0.5°C trip accuracy over full commercial temperature range without calibration. |
| Power Sequencing Controller | Level-Shifting Interface |
|
Use Scenario: Validating correct startup order of multiple DC/DC rails (e.g., 1.2 V core before 3.3 V I/O) in FPGA systems. IC Role / Device Role / Timing Role: Each comparator monitors one rail with dedicated reference; open-drain OR-ing diodes combine outputs to generate global POWER_GOOD. Use Value: Push-pull outputs eliminate need for external pullups - simplifies layout and avoids timing skew between rail monitors. |
Use Scenario: Translating 1.8 V logic signals to 5 V levels for legacy peripherals in mixed-voltage microcontroller systems. IC Role / Device Role / Timing Role: Comparator 1 configured as rail-to-rail input buffer with 1.8 V reference on IN1− and signal on IN1+; OUT1 drives 5 V load.

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 | Open-collector output, 2 mV higher typical offset (7 mV), 10× higher supply current (500 μA). | Requires external pullup; unsuitable for ultra-low-power or capacitive-load-driven timing-critical paths. | Select LM393DR only when cost is primary constraint and system can tolerate higher current draw and slower rise time. |
| TLC3702CDR | Identical electrical specs and SOIC-8 packaging; R suffix denotes tape-and-reel packaging (same pinout, same thermal profile). | No functional difference - differs only in packaging format (reel vs. tube); identical performance and qualification. | Choose TLC3702CDR for automated SMT assembly; TLC3702CPSRG4 is functionally interchangeable but supplied in tube format. |
Compared with LM393DR, TLC3702CPSRG4 delivers 10× lower supply current and faster rise/fall times due to push-pull output, while TLC3702CDR offers identical functionality in tape-and-reel form - making TLC3702CPSRG4 optimal for low-power prototyping and small-batch production where tube delivery is preferred.

FAQ
What is the maximum operating supply voltage for TLC3702CPSRG4?
The absolute maximum supply voltage for TLC3702CPSRG4 is 18 V, but the recommended operating range is 3 V to 16 V. Operation at 16 V is fully characterized for all parameters including input offset voltage, propagation delay, and output drive strength across 0°C to 70°C. Exceeding 16 V risks parametric degradation and reduced long-term reliability.
Does TLC3702CPSRG4 support rail-to-rail input operation?
TLC3702CPSRG4 supports a common-mode input voltage range of 0 V to VDD − 1.5 V at full temperature range, meaning it accepts inputs down to ground but does not reach the positive rail. For true rail-to-rail input, consider TLV3702 - however, TLC3702CPSRG4's 0 V lower limit enables direct connection to ground-referenced sensors without level-shifting circuitry.
Can TLC3702CPSRG4 drive a 1000-pF capacitive load reliably?
TLC3702CPSRG4 is characterized for 50 pF loads with 2.7 μs tPLH; driving 1000 pF causes significant rise/fall time degradation (measured >100 ns transition time in typical layouts). For >100 pF loads, add a series resistor (22–47 Ω) close to the output pin to damp ringing and maintain stability - do not rely on inherent drive strength beyond 100 pF.
Is there internal hysteresis in TLC3702CPSRG4?
No, TLC3702CPSRG4 has no internal hysteresis. It is a precision comparator designed for external hysteresis implementation via positive feedback from output to non-inverting input. Typical values use 1 MΩ feedback resistor with 10 kΩ to reference to achieve ~10 mV hysteresis - essential for noise immunity in sensor threshold applications.
What is the input bias current specification for TLC3702CPSRG4 at 70°C?
At 70°C, the input bias current for TLC3702CPSRG4 is specified at a maximum of 0.6 nA. This value is confirmed in the "electrical characteristics" table for TLC3702C under TA = 0°C to 70°C conditions, ensuring minimal loading on high-impedance sources such as photodiodes or RC timing networks in precision analog front-ends.
