Product details
Overview
TLC3702MDR from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, ±8 mA output drive capability, and 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive at VDD = 5 V. It operates from a single 4 V to 16 V supply and is rated for −55°C to 125°C military temperature range, enabling use in ruggedized power monitoring and precision threshold detection circuits.
For engineers reviewing the TLC3702MDR datasheet, TLC3702MDR pinout, TLC3702MDR application, or TLC3702MDR equivalent, this page delivers verified electrical specs, military-grade thermal performance data, push-pull output behavior without external pullups, and validated alternatives for high-reliability analog signal conditioning designs.
Technical Context
The TLC3702MDR implements two independent comparators using Texas Instruments' LinCMOS™ process, delivering ultra-low input bias current (5 pA typ at 25°C) and stable input offset voltage across temperature (≤10 mV over −55°C to 125°C). Its differential input stage supports common-mode voltages from 0 V to VDD − 1.5 V.
The push-pull CMOS output stage eliminates need for external pullup resistors, enabling direct capacitive load driving (CL = 50 pF) while maintaining fast response (tPHL = 2.3 μs typ at 5-mV overdrive) and TTL-compatible logic levels (VOH ≥ 4.2 V, VOL ≤ 500 mV at 125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - Enables operation in 5 V, 12 V, and 15 V industrial/military systems without level-shifting. |
| Input Offset Voltage (max) | 10 mV over −55°C to 125°C - Ensures reliable threshold detection across full military temperature range. |
| Propagation Delay (tPLH) | 2.7 μs typ at 5-mV overdrive, VDD = 5 V - Supports sub-400-kHz window-comparator timing in fault-detection circuits. |
| Output Drive Capability | ±8 mA - Sufficient to directly interface with TTL loads or drive small LEDs without external buffers. |
| Quiescent Supply Current | 90 μA max over −55°C to 125°C - Enables battery-backed or energy-constrained applications requiring long-term stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393AMX/NOPB | Open-collector output; requires external pullup; 2 mV offset max at 25°C but degrades to 7 mV over −40°C to 125°C. | Lacks push-pull drive; unsuitable for direct TTL interfacing or capacitive load switching. | Select when cost sensitivity outweighs output drive needs and pullup resistors are acceptable. |
| TLV3702IDR | Lower supply range (2.7 V to 16 V); 3.5 mV offset max over −40°C to 125°C; 50 μA IDD max - not qualified for military temp range. | Optimized for low-voltage portable electronics; lacks −55°C rating and 2 kV HBM ESD robustness. | Choose for commercial/industrial apps where extended cold start is not required and lower IDD is critical. |
Compared with LM393AMX/NOPB and TLV3702IDR, the TLC3702MDR uniquely combines military-temperature qualification, push-pull CMOS outputs eliminating external components, and guaranteed 10 mV offset across full operating range - making it the only option for high-reliability, component-count-sensitive designs in harsh environments.

FAQ
What is the maximum operating temperature range for the TLC3702MDR?
The TLC3702MDR is characterized for operation from −55°C to 125°C, meeting military-grade temperature specifications. This range is explicitly defined in the "recommended operating conditions" table for the TLC3702M variant, and the "D" package with "R" suffix (TLC3702MDR) retains this full qualification. No derating is required within this span for supply voltage or input common-mode range.
Does the TLC3702MDR require an external pullup resistor on its outputs?
No, the TLC3702MDR does not require an external pullup resistor. Its push-pull CMOS output stage actively drives both high and low states, delivering VOH ≥ 4.2 V and VOL ≤ 500 mV at 125°C while sourcing/sinking ±8 mA. This eliminates the need for pullup resistors used in open-collector comparators like the LM393, reducing component count and improving rise/fall times.
What is the input offset voltage specification for the TLC3702MDR over temperature?
The TLC3702MDR has a maximum input offset voltage of 10 mV over the full −55°C to 125°C operating range, as specified in the electrical characteristics table for the TLC3702M variant. At 25°C, the typical value is 1.2 mV, with a maximum of 5 mV - ensuring precise threshold detection even under extreme thermal stress.
Can the TLC3702MDR operate from a 3.3 V supply?
No, the TLC3702MDR cannot operate from a 3.3 V supply. Its minimum specified supply voltage is 4 V, per the "recommended operating conditions" for the TLC3702M variant. Attempting operation below 4 V may result in undefined output behavior, increased propagation delay, or failure to meet offset and drive specifications.
Is the TLC3702MDR pin-compatible with the standard TLC3702CDR or TLC3702IDR?
Yes, the TLC3702MDR is pin-compatible with TLC3702CDR and TLC3702IDR - all use the same SOIC-8 (D) package with identical pinout (OUT1, IN1−, IN1+, GND, VDD, OUT2, IN2−, IN2+). However, the TLC3702MDR's extended temperature rating and tighter parametric limits (e.g., 10 mV offset max vs. 6.5 mV for C-grade) make it a functional upgrade in demanding environments.
