Product details
Overview
TLC3704IDG4 from Texas Instruments is a quad micropower LinCMOS voltage comparator IC designed for single-supply operation (3 V to 16 V), delivering 2.7 µs typical propagation delay 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-speed replacement for LM339 in battery-powered sensors, industrial threshold detection, and precision level-shifting circuits.
For engineers reviewing the TLC3704IDG4 datasheet, TLC3704IDG4 pinout, TLC3704IDG4 application, or TLC3704IDG4 equivalent, key selection criteria include its rail-to-rail input range (0 V to VDD − 1.5 V), 5 mV max input offset voltage over −40°C to 85°C, ESD-protected inputs (2 kV HBM), and compatibility with TTL/CMOS logic without external pullups.
Technical Context
The TLC3704IDG4 integrates four independent comparators on a single die using Texas Instruments' LinCMOS process-enabling high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable offset voltage across temperature. Its push-pull output stage eliminates need for external pullup resistors while sustaining ±20 mA output current capability per channel.
Designed for robust single-supply systems, it supports common-mode input voltages from −0.2 V to VDD − 1.5 V, achieves 84 dB typical CMRR and 85 dB kSVR, and maintains functional operation across −40°C to 85°C industrial temperature range-validated per TLC3704I specifications.
Key Specifications

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 outputs require external pullup resistors; 1.3 mA typical supply current per comparator (5.2 mA total); slower response (~1.3 µs min but highly load-dependent). | Higher power consumption limits use in battery-critical designs; pullup dependency increases component count and layout complexity. | Select LM339DR only when legacy compatibility or cost sensitivity outweighs micropower and integration benefits of TLC3704IDG4. |
| TLC3702CDR | Dual-channel version (2 comparators); identical LinCMOS specs, SOIC-8 package; same 200 µW power, 2.7 µs delay, and −40°C to 85°C rating. | Requires two ICs to match quad functionality; increases PCB area and assembly cost versus single TLC3704IDG4. | Choose TLC3702CDR only if design uses exactly two comparators or space constraints favor smaller SOIC-8 footprint over SOIC-14. |
Compared with LM339DR, TLC3704IDG4 reduces total system power by >99% and eliminates four external pullup resistors; versus TLC3702CDR, it delivers full quad functionality in one package-cutting component count, test time, and bill-of-materials cost by 33% in four-channel applications.

FAQ
What is the operating temperature range for the TLC3704IDG4?
The TLC3704IDG4 is rated for industrial operation from −40°C to +85°C, as confirmed by the "TLC3704I" qualification data in the official datasheet. This range covers most factory-floor, outdoor, and automotive cabin applications without derating. The "IDG4" suffix denotes the SOIC-14 package with industrial temperature grade, distinct from commercial (C) or military (M) variants.
Does the TLC3704IDG4 require external pullup resistors on its outputs?
No, the TLC3704IDG4 features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pullup resistors. This design reduces total system power by ~200 µW per channel compared to open-collector comparators like LM339, saves PCB space, and simplifies layout-verified in the "Push-Pull CMOS Output Drives Capacitive Loads Without Pullup Resistor" section of the datasheet.
What is the maximum input common-mode voltage for the TLC3704IDG4?
The TLC3704IDG4 supports an input common-mode voltage range from −0.2 V to VDD − 1.5 V across its full −40°C to +85°C operating range. At 5 V supply, this means inputs can swing from −0.2 V to +3.5 V. Inputs exceeding these limits must be current-limited to ±5 mA to avoid damage-per absolute maximum ratings and input protection circuit documentation in the datasheet.
How does the TLC3704IDG4 compare to the LM339 in power consumption?
The TLC3704IDG4 consumes only 35–125 µA total supply current for all four comparators, whereas the LM339 draws approximately 500–800 µA per comparator (2–3.2 mA total). This represents a >99% reduction in quiescent power, enabling multi-year operation on coin-cell batteries-a key differentiator explicitly stated in the datasheet's "functionally similar to the LM339 but use 1/20th the power" description.
Is the TLC3704IDG4 pin-compatible with other TLC3704 variants?
Yes, all TLC3704 variants-including TLC3704CD, TLC3704ID, TLC3704MD, and TLC3704QD-share identical SOIC-14 pinouts and electrical behavior per channel. The "DG4" suffix specifically denotes the SOIC-14 package with industrial temperature grade (TLC3704I), ensuring mechanical and functional interchangeability across the family without PCB redesign.
