Product details
Overview
TLC3704ID from Texas Instruments is a quad micropower LinCMOS voltage comparator designed for single-supply operation (3 V to 16 V), delivering 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive, ±8 mA push-pull CMOS output drive, and only 200 µW typical supply power at 5 V. It serves as a low-power, high-precision signal threshold detector in industrial sensor interfaces and battery-powered monitoring systems.
For engineers reviewing the TLC3704ID datasheet, TLC3704ID pinout, TLC3704ID application, or TLC3704ID equivalent, this page provides verified electrical specifications, industrial-temperature-grade thermal performance (−40°C to 85°C), package mapping to SOIC-14 (D package), and validated alternative options for precision comparator selection in space- and power-constrained designs.
Technical Context
The TLC3704ID implements four 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 (≤7 mV max over −40°C to 85°C). Its push-pull CMOS output stage eliminates external pull-up resistors while driving capacitive loads directly - enabling fast, clean transitions without added board area or power loss.
This architecture supports rail-to-rail input common-mode range (0 V to VDD − 1.5 V) and TTL-compatible output levels, making it suitable for interfacing with mixed-signal microcontrollers and logic systems operating across wide supply voltages and temperature extremes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Open-collector output; requires external pull-up; higher supply current (500 µA typ); no ESD protection. | Lower cost but adds external components and increases power; unsuitable for capacitive-load timing-critical paths. | Select LM339DR only if legacy compatibility or open-drain bus-wire logic is required; avoid where low power or fast edge integrity matters. |
| TLC3702IDR | Dual-channel version (2 comparators); identical LinCMOS specs, same SOIC-8 package; 50% smaller footprint. | Applicable where only two thresholds needed; not drop-in for quad-channel layouts requiring 4 outputs. | Choose TLC3702IDR for space-constrained dual-sensing nodes; retain TLC3704ID when four independent comparisons are mandatory. |
Compared with LM339DR and TLC3702IDR, the TLC3704ID uniquely delivers quad-channel micropower performance with push-pull outputs and industrial-grade thermal stability - making it optimal for compact, battery-aware, and noise-sensitive embedded monitoring systems where layout simplicity and deterministic timing are critical.

FAQ
What is the operating temperature range of the TLC3704ID?
The TLC3704ID is specified for operation from −40°C to +85°C, qualifying it for industrial environments including factory automation, outdoor metering, and motor control systems. This range is explicitly defined in the "recommended operating conditions" table of the official datasheet (SLCS117C, Rev. November 2009), and distinguishes it from the commercial-grade TLC3704CD (0°C to 70°C) and military-grade TLC3704MD (−55°C to 125°C).
Does the TLC3704ID require an external pull-up resistor on its outputs?
No, the TLC3704ID features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pull-up resistors. This design reduces power consumption, saves PCB area, and improves rise/fall time symmetry - confirmed by the "Push-Pull CMOS Output Drives Capacitive Loads Without Pullup Resistor" statement in the device description and verified in the switching characteristics section (tPLH/tPHL test conditions assume no external pull-up).
What is the maximum input offset voltage for the TLC3704ID over its full temperature range?
The maximum input offset voltage for the TLC3704ID is 7 mV across the full industrial temperature range of −40°C to +85°C, as specified in the "electrical characteristics" table for the TLC3704I grade (which TLC3704ID implements). This value is measured under standard test conditions (VDD = 5 V, VIC = VICRmin) and represents the worst-case deviation guaranteeing reliable trip-point consistency in precision sensing applications.
Can the TLC3704ID operate from a 3.3 V supply?
Yes, the TLC3704ID supports a minimum supply voltage of 3 V, making it fully compatible with standard 3.3 V logic and microcontroller systems. Its rail-to-rail input common-mode range (0 V to VDD − 1.5 V) ensures valid operation down to 3 V, and its push-pull outputs deliver TTL-compatible levels (VOH ≥ 4.3 V at 5 V, scaled proportionally) - confirmed in the "recommended operating conditions" and "electrical characteristics" sections of the datasheet.
How does the TLC3704ID compare to the LM339 in terms of power consumption?
The TLC3704ID consumes approximately 1/20th the power of the LM339 for similar response times: 35–125 µA typical supply current versus ~500 µA for the LM339. This dramatic reduction stems from the LinCMOS process and optimized biasing, enabling battery-powered and thermally constrained applications where the LM339's higher quiescent draw would be prohibitive - a key differentiator explicitly stated in the device description.
