Product details
Overview
TLC3702MDREP from Texas Instruments is a dual micropower LinCMOS voltage comparator designed for single-supply operation (4V to 16V), delivering 2.7µs typical propagation delay (tPLH) with 5mV overdrive, ±8mA push-pull CMOS output drive, and 100µW typical power consumption at 5V - deployed in industrial monitoring, power supply supervision, and precision threshold detection circuits.
For engineers reviewing the TLC3702MDREP datasheet, TLC3702MDREP pinout, TLC3702MDREP application, or TLC3702MDREP equivalent, key selection considerations include its extended temperature range (−55°C to 125°C), rail-to-rail input capability (0 V to VDD − 1.5 V), absence of external pullup requirements, and compatibility with HCMOS/TTL logic interfaces.
Technical Context
The TLC3702MDREP integrates two independent comparators using Texas Instruments' LinCMOS process, combining high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ. at 25°C), and stable input offset voltage (1.2–15 mV) across temperature. Its differential pair input stage enables fast response without sacrificing micropower operation.
The push-pull output architecture eliminates external pullup resistors, directly sourcing/sinking up to ±8mA while maintaining TTL-compatible VOH (≥4.5V) and VOL (≤300mV) at 4mA load - enabling direct interface with logic gates, MOSFET drivers, and LED indicators without level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-collector output; requires external pullup; higher quiescent current (500µA vs. 40µA) | Not suitable for low-power or capacitive-load driving without additional components | Select when cost sensitivity outweighs power/performance needs and pullup resistors are acceptable |
| TLC372CDR | Same LinCMOS architecture but commercial temp range (0°C to 70°C); non-EP grade | Lacks radiation-hardened and extended-temperature qualification for aerospace/defense use | Select only for non-critical commercial applications where full −55°C to 125°C operation is unnecessary |
Compared with LM393DR and TLC372CDR, the TLC3702MDREP provides superior micropower efficiency, integrated push-pull drive eliminating BOM overhead, and guaranteed operation across military-grade temperature extremes - making it the sole choice for mission-critical, long-life, and thermally constrained designs.

FAQ
What is the maximum supply voltage rating for the TLC3702MDREP?
The absolute maximum supply voltage (VDD) for the TLC3702MDREP is 18V. However, the recommended operating range is 4V to 16V. Exceeding 18V risks permanent damage per the Absolute Maximum Ratings table. Operation above 16V may degrade parametric performance and reliability, especially at high temperatures. Always refer to Section 3.1 of the official SGLS127B datasheet for derating guidance.
Does the TLC3702MDREP require external pullup resistors on its outputs?
No, the TLC3702MDREP does not require external pullup resistors because it features a push-pull CMOS output stage capable of sourcing and sinking up to ±8mA. This architecture directly drives capacitive loads and logic inputs without power-wasting resistors - a key differentiator from open-collector comparators like the LM393. Using a pullup with TLC3702MDREP would cause contention and potential damage.
Can the TLC3702MDREP operate from a single 5V supply?
Yes, the TLC3702MDREP is explicitly designed for single-supply operation from 4V to 16V. At 5V, it delivers 2.7µs typical propagation delay with 5mV overdrive, 100µW typical power consumption, and full rail-to-rail input range (0 V to 3.5 V). Its LinCMOS process ensures stable performance across temperature, making it ideal for 5V embedded systems requiring low power and high accuracy.
What is the input bias current specification for the TLC3702MDREP at 125°C?
At 125°C, the input bias current (IIB) for the TLC3702MDREP is specified at 30 nA maximum, per Section 3.3 Electrical Characteristics in the SGLS127B datasheet. This remains exceptionally low compared to bipolar comparators and enables high-impedance sensor interfacing (e.g., pH electrodes, piezoresistive bridges) even in high-temperature environments without significant measurement error.
Is the TLC3702MDREP pin-compatible with the standard TLC3702 family?
Yes, the TLC3702MDREP is pin-compatible with other TLC3702 variants in the SOIC-8 (D) package, including TLC3702CDR and TLC3702IDR. All share identical pinout, electrical behavior, and footprint. The "MDREP" suffix denotes enhanced product - radiation-hardened, extended temperature (−55°C to 125°C), and controlled baseline manufacturing - but retains full mechanical and functional compatibility with commercial-grade TLC3702 devices.
