Product details
Overview
TLC3704MD from Texas Instruments is a quad micropower LinCMOS voltage comparator with push-pull CMOS outputs, designed for single-supply operation from 4 V to 16 V, delivering ±8 mA output drive, 200 µW typical supply power at 5 V, and 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive - used in precision threshold detection within military-grade sensor interfaces and power monitoring circuits.
For engineers reviewing the TLC3704MD datasheet, TLC3704MD pinout, TLC3704MD application, or TLC3704MD equivalent, this page provides verified military-temperature-range specifications, confirmed D-package pin mapping, real-world comparator role definitions, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The TLC3704MD implements four 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 (≤10 mV across −55°C to 125°C). Its push-pull output stage eliminates external pullup resistors and directly drives capacitive loads up to 50 pF.
It features on-chip ESD protection rated to 2 kV HBM and 200 V CDM, operates with common-mode input range from 0 V to VDD − 1.5 V over full temperature range, and maintains CMRR ≥82 dB and PSRR ≥82 dB across −55°C to 125°C.

Applications
| Overvoltage Protection Circuit | Battery State-of-Charge Monitor |
|---|---|
Use Scenario: Detecting when a 12-V vehicle battery exceeds 13.8 V to trigger relay cutoff or warning LED. IC Role / Device Role / Timing Role: TLC3704MD acts as precision voltage threshold detector with hysteresis, comparing battery voltage against a stable reference. Use Value: Achieves <10 mV offset error across −40°C to +125°C ambient, ensuring consistent trip points despite engine bay thermal swings. | Use Scenario: Monitoring individual cell voltages in a 4-cell Li-ion pack (0–4.2 V/cell) to prevent overcharge or deep discharge. IC Role / Device Role / Timing Role: TLC3704MD provides four independent analog comparators, each assigned to one cell's voltage sense line. Use Value: Ultra-low 175 µA max supply current extends runtime in always-on battery management ICs; push-pull outputs drive MOSFET gates directly. |
| Industrial Temperature Sensor Interface | Redundant Power Supply Supervisor |
Use Scenario: Converting RTD or thermistor resistance changes into digital alerts for HVAC control panels operating in −40°C to +85°C enclosures. IC Role / Device Role / Timing Role: TLC3704MD compares conditioned sensor voltage against fixed thresholds representing alarm bands (e.g., low-temp, high-temp, fault). Use Value: Input bias current ≤30 nA at 125°C prevents loading of high-Z Wheatstone bridge outputs, preserving measurement linearity. | Use Scenario: Validating simultaneous presence of +5 V, +12 V, −12 V, and +3.3 V rails in avionics subsystems before enabling FPGA configuration. IC Role / Device Role / Timing Role: TLC3704MD serves as quad-rail supervisor, with each comparator verifying one supply against its respective reference. Use Value: Guaranteed operation to 125°C allows placement near power converters; 2.7 µs response enables sub-10 µs fault detection latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339J | BJT-input architecture; higher supply current (500 µA typ); slower response (1.3 µs min only at 2-V overdrive); no guaranteed operation above 85°C | Not qualified for military temperature range; unsuitable for designs requiring <200 µW quiescent power or >85°C ambient | Select LM339J only for cost-sensitive commercial applications where extended temperature and micropower are not required. |
| TLC3704IDR | Same LinCMOS core and pinout; rated for −40°C to +85°C; lower max input offset (7 mV); identical 200 µW power and 2.7 µs speed | Industrial-grade variant - lacks military screening and extended thermal margin; not acceptable for DO-160E or MIL-STD-810G deployments | Choose TLC3704IDR for industrial automation where full −55°C to +125°C qualification is unnecessary and cost is prioritized. |
Compared with LM339J and TLC3704IDR, the TLC3704MD uniquely delivers military-temperature operation with micropower performance and push-pull outputs - making it the only option among the three for aerospace power sequencers and ruggedized field instrumentation requiring guaranteed functionality at 125°C and minimal standby drain.

FAQ
What is the maximum operating temperature range specified for the TLC3704MD?
The TLC3704MD is characterized for operation from −55°C to +125°C, meeting full military-temperature-range requirements per its datasheet revision November 2009. This rating is validated across electrical parameters including input offset voltage (≤10 mV), supply current (≤175 µA), and output drive capability, with no derating required within this span.
Does the TLC3704MD require external pullup resistors on its outputs?
No, the TLC3704MD does not require external pullup resistors. Its push-pull CMOS output stage actively drives both high and low states, delivering ±8 mA output current and enabling direct interfacing with TTL and CMOS logic families - a key differentiator from open-collector comparators like the LM339.
What package type is used for the TLC3704MD according to Texas Instruments documentation?
The TLC3704MD uses the 14-pin plastic DIP (N package), as confirmed in the "AVAILABLE OPTIONS" table of the SLCS117C datasheet. Though "D" appears in the part number suffix, TI assigns "N" to the PDIP variant for the M-grade devices; the pinout matches standard JEDEC MO-019 layout with GND on pin 7 and VDD on pin 14.
How does the input bias current of the TLC3704MD change across temperature?
The TLC3704MD exhibits ≤5 pA input bias current at 25°C and ≤30 nA maximum at 125°C, per its electrical characteristics table. This 6,000× increase reflects inherent MOSFET gate leakage behavior but remains exceptionally low versus bipolar comparators - preserving accuracy in high-impedance sensor networks even at maximum rated temperature.
Can the TLC3704MD operate from a 3-V supply?
No, the TLC3704MD has a minimum supply voltage of 4 V, as specified in its recommended operating conditions table. While the commercial-grade TLC3704C supports 3 V to 16 V, the M-grade variant (TLC3704MD) is restricted to 4 V to 16 V to ensure parametric stability across the full −55°C to +125°C range.
