Product details
Overview
TLC3704IDR from Texas Instruments is a quad micropower LinCMOS voltage comparator with push-pull CMOS outputs, designed for single-supply operation from 3 V to 16 V, delivering 2.7 µs typical propagation delay (tPLH) at 5-mV overdrive, ±8 mA output drive, and 200 µW typical supply power at 5 V. It serves as a low-power, fast-response replacement for LM339 in battery-powered sensor interfaces and precision threshold detection.
For engineers reviewing the TLC3704IDR datasheet, TLC3704IDR pinout, TLC3704IDR application, or TLC3704IDR equivalent, key selection criteria include its rail-to-rail input common-mode range (0 V to VDD − 1.5 V), ultra-low input bias current (5 pA typ at 25°C), military-grade temperature rating (−40°C to 85°C), and absence of external pullup resistors due to integrated push-pull output stage.
Technical Context
The TLC3704IDR implements four independent comparators using Texas Instruments' LinCMOS process, combining high input impedance (>1012 Ω), stable input offset voltage (≤5 mV max at 25°C), and robust ESD protection (2 kV HBM). Each comparator features differential inputs with common-mode range extending to within 1.5 V of VDD and GND.
Its push-pull CMOS output stage eliminates reliance on external pullup resistors-enabling direct capacitive load driving up to 50 pF while maintaining sub-3 µs response time and full TTL compatibility. Input protection circuitry clamps overvoltage transients via internal zener-diode and MOSFET-based shunting without degrading dc accuracy.

Applications
| Industrial Threshold Monitoring | Battery Voltage Supervision |
|---|---|
Use Scenario: Detecting overtemperature, overcurrent, or pressure limit breaches in programmable logic controllers and motor drives. IC Role / Device Role / Timing Role: Quad comparator provides simultaneous high/low threshold comparison for fault latching and alarm generation. Use Value: 2.7 µs response ensures rapid shutdown before thermal runaway; ±8 mA drive directly activates optocouplers or latch circuits. | Use Scenario: Monitoring cell voltage in 2S–4S Li-ion packs to trigger charge termination or low-battery warning. IC Role / Device Role / Timing Role: Compares battery voltage against precision reference to assert RESET or ALERT signals. Use Value: 35 µA quiescent current extends shelf life; rail-to-rail input accommodates full 0–16 V measurement range without attenuation. |
| Sensor Signal Conditioning | Power Supply Sequencing |
Use Scenario: Converting analog outputs from thermistors, RTDs, or Hall-effect sensors into clean digital logic levels. IC Role / Device Role / Timing Role: Amplifier-comparator interface stage converting slow-moving analog signals into TTL-compatible edges. Use Value: 5 pA input bias prevents loading of high-Z sensor bridges; low offset minimizes calibration drift across temperature. | Use Scenario: Ensuring correct power-up/down order of multiple rails (e.g., 12 V → 5 V → 3.3 V) in FPGA or DSP systems. IC Role / Device Role / Timing Role: Four independent comparators monitor each rail's voltage and enable downstream regulators only when valid. Use Value: Single SOIC-14 package replaces four discrete comparators - simplifies layout and improves timing consistency across rails. |
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 requiring external pullup; higher supply current (500 µA typ); slower response (~1.3 µs min but highly load-dependent) | Requires additional resistor network; less suitable for low-power or high-speed capacitive loads | Select LM339DR only if legacy design reuse or cost sensitivity outweighs power/performance needs |
| TLC3702IDR | Dual-channel version in same SOIC-8 package; identical electrical specs except channel count and pinout | Used where only two comparators are needed; saves board space but requires redesign for quad functionality | Choose TLC3702IDR for space-constrained dual-comparator applications; not drop-in for TLC3704IDR |
Compared with LM339DR, TLC3704IDR delivers 20× lower quiescent power and eliminates pullup resistors; compared with TLC3702IDR, it provides double the channel count in a larger SOIC-14 footprint-making TLC3704IDR optimal for compact, multi-threshold industrial sensing where power and integration matter.

FAQ
What is the maximum operating supply voltage for TLC3704IDR?
The absolute maximum supply voltage for TLC3704IDR is 18 V, but the recommended operating range is 3 V to 16 V. Operation above 16 V risks exceeding safe dissipation limits and may degrade long-term reliability-even though the device may function temporarily. Always observe derating curves in the datasheet for ambient temperatures above 25°C.
Does TLC3704IDR require external pullup resistors on its outputs?
No, TLC3704IDR does not require external pullup resistors because it features a push-pull CMOS output stage capable of sourcing and sinking up to ±8 mA. This architecture eliminates the power loss and board space associated with pullup resistors while enabling direct drive of capacitive loads up to 50 pF with guaranteed 2.7 µs response time.
What is the input common-mode voltage range of TLC3704IDR?
The input common-mode voltage range of TLC3704IDR is 0 V to VDD − 1.5 V across its full operating temperature range (−40°C to +85°C). At 25°C, it extends to 0 V to VDD − 1 V. This rail-to-rail capability allows direct interfacing with unbuffered sensors and reference voltages without level-shifting circuitry.
Can TLC3704IDR be used in place of LM339 in existing designs?
TLC3704IDR is functionally compatible with LM339 but not pin-compatible: LM339 uses open-collector outputs and requires external pullups, whereas TLC3704IDR has push-pull outputs and different pin assignments (e.g., VDD on pin 14 vs. pin 16 on LM339). Board redesign is required to replace LM339 with TLC3704IDR-but the change yields 20× lower power and faster, more predictable timing.
What is the input offset voltage specification for TLC3704IDR over temperature?
TLC3704IDR has a maximum input offset voltage of 7 mV over its full operating range of −40°C to +85°C, with a typical value of 1.2–5 mV at 25°C. The datasheet specifies this limit under conditions that ensure output saturation (VOH ≥ 4.3 V or VOL ≤ 400 mV), making it suitable for precision threshold detection where offset-induced errors must stay below 10 mV.
