Product details
Overview
TLC3704QDRQ1 from Texas Instruments is a quad micropower voltage comparator with push-pull CMOS outputs, designed for single-supply automotive applications (−40°C to 125°C). It delivers 2.7 µs typical propagation delay at 5-mV overdrive, 200 µW typical supply power at 5 V, and ±8 mA output drive-enabling direct capacitive load driving without pullup resistors in battery-powered sensor monitoring circuits.
For engineers reviewing the TLC3704QDRQ1 datasheet, TLC3704QDRQ1 pinout, TLC3704QDRQ1 application, or TLC3704QDRQ1 equivalent, key selection criteria include its AEC-Q100 qualified operation, 5 mV max input offset voltage at 25°C, rail-to-rail input common-mode range (0 to VDD − 1.5 V), and compatibility with HCMOS/TTL logic interfaces in space-constrained automotive subsystems.
Technical Context
The TLC3704QDRQ1 implements four independent comparators using Texas Instruments' LinCMOS process, combining high input impedance (>1012 Ω), ultra-low input bias current (1 pA typ at 25°C), and stable input offset voltage (≤5 mV at 25°C, ≤7 mV over full temperature range). Its differential input stage supports common-mode voltages up to VDD − 1.5 V across −40°C to 125°C.
Each comparator features a push-pull CMOS output capable of sourcing/sinking ±20 mA, eliminating external pullup resistors while maintaining fast switching (tPLH/tPHL ≤ 2.7 µs / 2.3 µs typ at 5 V, 5-mV overdrive) and full TTL compatibility. ESD protection exceeds 2000 V (HBM) and 50 V (MM), meeting automotive handling requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct integration into 5 V, 12 V, and wide-input automotive power domains without level-shifting. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures reliable threshold detection in precision voltage monitoring (e.g., battery undervoltage lockout). |
| Propagation Delay (tPLH) | 2.7 µs typ at 5 V, 5-mV overdrive - supports sub-100-kHz signal conditioning in motor control feedback loops. |
| Supply Current (all 4) | 80 µA typ at 5 V, 25°C - enables multi-year operation on coin-cell batteries in always-on vehicle status monitors. |
| Output Drive Capability | ±20 mA per output - directly drives LEDs, small relays, or logic inputs without external buffers in distributed sensor nodes. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - accommodates signals near ground or rail in single-supply systems like 12-V body electronics. |

Applications
| Battery Voltage Monitor | Motor Speed Control |
|---|---|
Use Scenario: Real-time monitoring of 12-V lead-acid battery voltage during engine start-stop cycles to prevent deep discharge. IC Role / Device Role / Timing Role: Quad comparator configures dual thresholds (undervoltage lockout and overvoltage warning) with hysteresis via external resistors. Use Value: 5 mV input offset ensures accurate 11.8 V / 14.2 V trip points; 2.7 µs response prevents false triggering during cranking transients. | Use Scenario: Generating PWM signals for brushed DC motor speed regulation in HVAC blower assemblies. IC Role / Device Role / Timing Role: One comparator compares sawtooth oscillator voltage against control voltage; others manage direction and enable logic. Use Value: Push-pull outputs drive gate drivers directly; 3–16 V supply range matches vehicle battery fluctuations without regulation. |
| Enhanced Power Supervisor | Two-Phase Clock Generator |
Use Scenario: Monitoring multiple rails (5 V, 12 V) in ADAS domain controllers to trigger safe shutdown before brownout. IC Role / Device Role / Timing Role: Dedicated comparators supervise each rail independently; open-drain equivalents would require pullups, increasing leakage. Use Value: Rail-to-rail input range allows direct connection to unregulated supplies; 80 µA total IDD minimizes impact on standby current budget. | Use Scenario: Generating non-overlapping clock phases for synchronous rectification in automotive DC-DC converters. IC Role / Device Role / Timing Role: Two comparators form oscillator core; third and fourth generate complementary, dead-time-controlled outputs. Use Value: 200 µW quiescent power enables continuous clock generation in always-on converter standby mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339QDRQ1 | Higher supply current (500 µA typ), open-collector outputs requiring pullup resistors, 2 mV higher typical input offset (7 mV max). | Less suitable for ultra-low-power battery backup systems; requires additional passive components for logic interfacing. | Select when legacy LM339 footprint compatibility is mandatory and power budget allows >2× increase. |
| TLC3702QDRQ1 | Dual-channel version (2 comparators), identical electrical specs and LinCMOS process, same 14-pin SOIC package pin-compatible subset. | Used where only two thresholds are needed; saves cost and board space but lacks channel count for multi-rail supervision. | Select for dual-comparator applications to maintain identical performance and layout reuse with half the channel count. |
Compared with LM339QDRQ1, TLC3704QDRQ1 reduces system power by 75% and eliminates four pullup resistors; compared with TLC3702QDRQ1, it doubles channel density for compact multi-threshold designs without sacrificing micropower operation or automotive temperature range.

FAQ
What is the maximum operating temperature range for the TLC3704QDRQ1?
The TLC3704QDRQ1 is qualified for operation from −40°C to 125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for automotive under-hood and powertrain applications. This rating is validated across all electrical parameters including input offset voltage (≤7 mV), supply current (≤175 µA), and propagation delay stability.
Does the TLC3704QDRQ1 require external pullup resistors on its outputs?
No, the TLC3704QDRQ1 features push-pull CMOS outputs that actively drive both high and low states, eliminating the need for external pullup resistors. This reduces board space, component count, and static power consumption-unlike open-collector comparators such as the LM339QDRQ1 which require external pullups for logic-level translation.
What is the input common-mode voltage range of the TLC3704QDRQ1?
The TLC3704QDRQ1 supports an input common-mode voltage range of 0 V to VDD − 1.5 V across its full operating temperature range (−40°C to 125°C). At 5 V supply, this permits valid operation from 0 V to 3.5 V, enabling direct interface with sensors and dividers referenced to ground or supply rails without level-shifting circuitry.
How does the TLC3704QDRQ1 compare to standard CMOS comparators in terms of input bias current?
The TLC3704QDRQ1 achieves 1 pA typical input bias current at 25°C and ≤30 nA at 125°C due to Texas Instruments' LinCMOS process-orders of magnitude lower than generic CMOS comparators. This enables high-impedance sensor interfaces (e.g., thermistors, photodiodes) without significant measurement error from input loading.
Is the TLC3704QDRQ1 pin-compatible with the industry-standard LM339?
No, the TLC3704QDRQ1 is not pin-compatible with the LM339. While both are quad comparators, the TLC3704QDRQ1 uses a 14-pin SOIC package with dedicated pins for all eight inputs and four outputs, whereas the LM339 uses a 14-pin package with shared ground and VCC pins but different pin assignments (e.g., LM339 pin 1 is OUT1, TLC3704QDRQ1 pin 1 is 1IN+). Layout redesign is required for migration.
