Product details
Overview
TLC3702QPA from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 2.7 μs typical propagation delay (tPLH) at 5-mV overdrive, ±8 mA output drive capability, and 100 μW typical supply power at 5 V. It operates from a single 3 V to 16 V supply and is used in precision threshold detection for battery-powered instrumentation and low-power sensor interfaces.
For engineers reviewing the TLC3702QPA datasheet, TLC3702QPA pinout, TLC3702QPA application, or TLC3702QPA equivalent, this page delivers verified electrical specs, military-grade temperature validation (−55°C to 125°C), package mapping to FK ceramic flatpack, and two confirmed alternative comparators with documented functional and thermal differences.
Technical Context
The TLC3702QPA implements two independent comparators using Texas Instruments' LinCMOS™ process, enabling high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage (≤5 mV max at 25°C). Its push-pull output stage eliminates external pullup resistors while delivering TTL-compatible logic levels and driving up to 50 pF capacitive loads.
Designed for single-supply operation across −55°C to 125°C, it supports common-mode input ranges from 0 V to VDD − 1.5 V and features on-chip ESD protection rated to 2 kV HBM and 200 V CDM-critical for ruggedized aerospace and defense systems where the 5962-9153202QPA MIL-PRF-38535 qualified variant is deployed.
Key Specifications

| Operating Temperature | −55°C to 125°C - Qualified per MIL-PRF-38535, Revision Q, for spaceflight and avionics applications. |
Pinout & Package
Ceramic flatpack (FK) package, 20-pin, hermetically sealed, lead finish gold over nickel. Pin 1 identified by notch; pin 10 is GND, pin 20 is VDD. No internal connection (NC) pins occupy positions 1, 3, 5, 6, 7, 9, 11, 13, 14, 16, and 19.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT (Pin 2) | Comparator 1 output | Push-pull CMOS output capable of sourcing/sinking ±8 mA; no external pullup required. |
| 1IN− (Pin 4) | Comparator 1 inverting input | Differential input node with 5 pA max bias current; supports rail-to-rail common-mode range. |
| 1IN+ (Pin 6) | Comparator 1 noninverting input | High-impedance input (≥1012 Ω); enables precision reference comparison with minimal loading. |
| GND (Pin 10) | Analog ground reference | Common return for both comparators and internal ESD protection network; must be low-impedance. |
| VDD (Pin 20) | Positive supply rail | Accepts 4 V–16 V; powers both comparators and output stages; decoupling capacitor required at pin. |
| 2OUT (Pin 18) | Comparator 2 output | Independent push-pull output; electrically isolated from 1OUT but shares same VDD/GND rails. |
| 2IN− (Pin 15) | Comparator 2 inverting input | Matches 1IN− performance; allows differential pair configuration or independent signal monitoring. |
| 2IN+ (Pin 17) | Comparator 2 noninverting input | Enables dual-threshold detection (e.g., window comparator) when paired with 1IN+/1IN−. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393AMX/NOPB | Open-collector output; requires external pullup; 1.3 mA supply current; −40°C to 125°C rating. | Lacks push-pull drive and micropower efficiency; suitable only where output polarity flexibility or cost dominates. | Select only if legacy open-collector interface is mandatory and power budget exceeds 10× that of TLC3702QPA. |
| MAX971ESA+ | Push-pull output; 1.5 μA supply current; −40°C to 85°C; no military qualification or FK packaging. | Lower power than TLC3702QPA but unqualified for aerospace use; lacks MIL-PRF-38535 traceability and radiation assurance. | Consider for commercial industrial controls where temperature range and qualification are not mission-critical. |
Compared with LM393AMX/NOPB and MAX971ESA+, the TLC3702QPA uniquely combines military temperature range, hermetic FK packaging, push-pull drive, and sub-100 μA supply current - making it irreplaceable in DoD and NASA programs requiring concurrent reliability, efficiency, and environmental robustness.

FAQ
What is the maximum operating temperature for the TLC3702QPA?
The TLC3702QPA is fully characterized and qualified for continuous operation from −55°C to 125°C per MIL-PRF-38535, Revision Q. This includes validated electrical performance, reliability testing, and hermetic seal integrity at both temperature extremes - unlike commercial variants such as TLC3702CD which are limited to 0°C–70°C.
Does the TLC3702QPA require external pullup resistors on its outputs?
No. The TLC3702QPA features a push-pull CMOS output stage capable of sourcing and sinking ±8 mA, eliminating the need for external pullup resistors. This reduces system power consumption by ≥100 μW per channel and saves PCB space - a key differentiator versus open-collector comparators like the LM393AMX/NOPB.
Is the TLC3702QPA pin-compatible with other TLC3702 variants?
Yes, the TLC3702QPA shares identical pinout and footprint with all TLC3702 family members in the FK package, including TLC3702MFK. However, electrical specifications differ: TLC3702QPA is screened to stricter military limits (e.g., ≤10 mV input offset over full temperature range), while TLC3702MFK may have looser characterization tolerances.
What package type does the TLC3702QPA use, and why is it significant?
The TLC3702QPA uses a 20-pin ceramic flatpack (FK) package with gold-plated leads and hermetic sealing. This construction provides superior moisture resistance, thermal cycling endurance, and long-term reliability in vacuum or high-humidity environments - essential for satellite payloads and airborne electronics where plastic packages would fail prematurely.
How does the LinCMOS™ process benefit the TLC3702QPA's performance?
The LinCMOS™ process enables the TLC3702QPA to achieve 5 pA typical input bias current, <10 mV input offset voltage over −55°C to 125°C, and exceptional CMRR (84 dB) and PSRR (85 dB). These traits stem from polysilicon-gate analog optimization - not standard digital CMOS - allowing precision analog functions in micropower form factors impossible with conventional processes.
