Product details
Overview
TLC3704CDR from Texas Instruments is a quad micropower LinCMOS voltage comparator with push-pull CMOS outputs, 200 µW typical supply power at 5 V, 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive, and single-supply operation from 3 V to 16 V. It replaces LM339 in low-power industrial sensing, battery-powered monitoring, and precision threshold detection circuits where pullup resistors must be eliminated.
For engineers reviewing the TLC3704CDR datasheet, TLC3704CDR pinout, TLC3704CDR application, or TLC3704CDR equivalent, key selection factors include its rail-to-rail input common-mode range (0 V to VDD − 1.5 V), ±8 mA output drive capability, 5 mV max input offset voltage over 0°C to 70°C, and D-package SOIC-14 tape-and-reel availability.
Technical Context
The TLC3704CDR implements four independent comparators using Texas Instruments' LinCMOS process, delivering high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage across temperature. Its push-pull output stage eliminates external pullup resistors while driving capacitive loads directly - enabling fast, low-power switching without TTL/CMOS interface compromises.
Designed for single-supply systems, it supports common-mode input voltages down to ground and up to VDD − 1.5 V, with ESD protection rated to 2 kV HBM and 200 V CDM. The device meets commercial-grade specifications (0°C to 70°C) and is characterized with 5 mV max input offset voltage at 25°C and 6.5 mV max over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct integration into 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Quiescent Supply Current | 35–80 µA per comparator (140–320 µA total) - supports multi-year battery life in always-on sensor nodes. |
| Propagation Delay (tPLH) | 2.7 µs typ @ 5-mV overdrive - provides deterministic timing for window comparators and zero-crossing detectors. |
| Input Offset Voltage | ≤5 mV max @ 25°C; ≤6.5 mV max @ 0°C to 70°C - ensures reliable threshold detection within ±5 mV accuracy. |
| Output Drive Capability | ±8 mA - drives LEDs, logic inputs, or small MOSFET gates directly without external buffers. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - allows direct sensing of signals referenced to ground in single-supply configurations. |
| ESD Protection | 2 kV HBM, 200 V CDM - reduces handling sensitivity and improves board-level robustness during assembly. |

| Single-supply compatibility | Operates from 3 V to 16 V - avoids dual supplies in battery-powered or industrial control systems. |
Applications
| Overvoltage Protection Circuit | Battery State-of-Charge Monitor |
|---|---|
Use Scenario: Detects when input voltage exceeds a preset threshold (e.g., 4.2 V for Li-ion cell) to disable charging or trigger shutdown. IC Role / Device Role / Timing Role: Quad comparator configured as window detector and overvoltage latch with hysteresis. Use Value: Enables precise, low-power cutoff without external op-amps or voltage references - reduces component count by ≥3 parts. | Use Scenario: Monitors battery terminal voltage across multiple cells to estimate remaining capacity and prevent deep discharge. IC Role / Device Role / Timing Role: Four independent comparators compare cell voltages against fixed thresholds (e.g., 3.0 V, 3.3 V, 3.6 V, 4.2 V). Use Value: Delivers accurate state-of-charge indication using only passive dividers and TLC3704CDR - eliminates need for dedicated fuel-gauge ICs. |
| Industrial Temperature Threshold Detector | Optical Smoke Sensor Signal Comparator |
Use Scenario: Compares thermistor-derived voltage against calibrated reference to detect overheating in motor drives or power supplies. IC Role / Device Role / Timing Role: Precision comparator with low input bias current minimizes thermistor measurement error. Use Value: Achieves ±0.5°C detection accuracy over 0°C to 70°C using standard 10-kΩ NTC thermistors - no calibration required. | Use Scenario: Converts photodiode current from smoke chamber into digital alarm signal based on light-scattering intensity. IC Role / Device Role / Timing Role: High-speed comparator detects rapid signal transitions caused by smoke particles interrupting IR beam. Use Value: Provides sub-5 µs response to smoke events - meets UL 217 fast-response requirements without additional amplification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC3702CDR | Dual-channel version in same SOIC-8 package; identical electrical specs except channel count and pinout. | Suitable when only two comparators are needed - reduces footprint and cost in space-constrained designs. | Select TLC3702CDR if system requires exactly two comparators and board layout favors SOIC-8. |
| LM339DR | Bipolar input stage; higher supply current (500 µA typ); open-collector outputs require external pullups; wider temp range (−40°C to 85°C). | Better suited for high-speed, high-noise industrial environments where speed > power is prioritized. | Choose LM339DR only when legacy compatibility or bipolar input ruggedness is mandatory - avoid if micropower or pullup-free design is required. |
Compared with TLC3702CDR and LM339DR, the TLC3704CDR uniquely balances ultra-low power (200 µW), push-pull outputs, and quad integration in SOIC-14 - making it optimal for new designs targeting battery life, board area, and simplified interface.

FAQ
What is the maximum operating temperature range for the TLC3704CDR?
The TLC3704CDR is specified for the commercial temperature range of 0°C to 70°C. This rating is confirmed in the "Available Options" table and "Recommended Operating Conditions" section of the SLCS117C datasheet. Devices marked with the "C" suffix (e.g., TLC3704CDR) are not rated for industrial or extended ranges - for −40°C to 85°C operation, the TLC3704IDR variant must be selected.
Does the TLC3704CDR require external pullup resistors on its outputs?
No, the TLC3704CDR does not require external pullup resistors. Its push-pull CMOS output stage actively drives both high and low states, enabling direct connection to CMOS, TTL, or microcontroller inputs. This architecture eliminates the power loss, board space, and timing uncertainty associated with pullup resistors - a key differentiator from open-collector comparators like the LM339.
What is the input offset voltage specification for the TLC3704CDR?
The TLC3704CDR has a maximum input offset voltage of 5 mV at 25°C and 6.5 mV across the full 0°C to 70°C operating range. These values are explicitly listed in the "Electrical Characteristics" tables for the TLC3704C grade and verified under VDD = 5 V, VIC = VICRmin test conditions. The typical value is 1.2 mV at 25°C.
Can the TLC3704CDR operate from a 3.3 V supply?
Yes, the TLC3704CDR supports supply voltages as low as 3 V, making it fully compatible with 3.3 V systems. At 3.3 V, its output high voltage remains functional (VOH ≥ 2.8 V at IOL = −4 mA), common-mode input range extends from 0 V to 1.8 V, and quiescent current stays below 100 µA - ensuring reliable operation in modern low-voltage embedded designs.
Is the TLC3704CDR pin-compatible with the LM339?
No, the TLC3704CDR is not pin-compatible with the LM339. While both are quad comparators in 14-pin packages, the TLC3704CDR uses SOIC-14 (D package) with NC pins at positions 8 and 14, whereas the LM339 uses SOIC-14 with GND at pin 4 and VCC at pin 12. Direct replacement requires PCB layout revision - however, functional equivalence exists with appropriate schematic adaptation.
