Product details

Overview

TLC3704IPW 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 ±8 mA output drive, 2.7 µs typical propagation delay (tPLH) at 5-mV overdrive, and only 200 µW typical supply power at 5 V. It serves as a low-power, space-efficient replacement for LM339 in battery-powered sensors, industrial monitoring interfaces, and precision threshold-detection circuits.

For engineers reviewing the TLC3704IPW datasheet, TLC3704IPW pinout, TLC3704IPW application, or TLC3704IPW equivalent, key selection criteria include its industrial-temperature rating (−40°C to 85°C), TSSOP-14 package footprint, rail-to-rail input common-mode range (0 V to VDD − 1.5 V), and absence of external pullup resistors due to integrated push-pull output stage.

Technical Context

The TLC3704IPW 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 (≤5 mV max at 25°C). Each comparator features fully 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 (e.g., 50 pF) while maintaining fast response (tPHL = 2.3 µs typ at 5-mV overdrive) and TTL-compatible logic levels - VOH ≥ 4.3 V and VOL ≤ 400 mV under full industrial temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 16 V - supports wide-input single-supply systems including 3.3 V, 5 V, and 12 V rails without level-shifting.
Quiescent Supply Current	35–125 µA (all four channels) - enables multi-year battery life in always-on sensor nodes and portable instrumentation.
Propagation Delay	tPLH = 2.7 µs / tPHL = 2.3 µs (5-mV overdrive, CL = 50 pF) - sufficient for kHz-level window-comparison and analog-to-digital front-end sampling control.
Input Offset Voltage	≤7 mV (−40°C to 85°C) - ensures reliable detection of ≥10 mV signal differentials in precision level-shift monitoring.
Output Drive Capability	±20 mA per output - directly interfaces with LED indicators, small relays, or microcontroller GPIOs without buffer stages.
Input Common-Mode Range	0 V to VDD − 1.5 V - accommodates ground-referenced signals and high-side sensing up to 14.5 V on 16 V supply.
ESD Protection	2000 V HBM, 200 V CDM - meets industrial handling requirements without external protection diodes.

Pinout & Package

TLC3704IPW uses a 14-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm pitch, measuring 5.0 mm × 4.4 mm × 1.2 mm - optimized for high-density PCB layouts and automated SMT assembly.

7 (4IN−)	Inverting input, Comparator 4	Final independent input; usable for fault flag aggregation or redundant sensing.
8 (GND)	Ground reference	Analog and digital return path; must be low-impedance for stable offset and noise immunity.
9 (4IN+)	Non-inverting input, Comparator 4	Completes quad-channel set; allows four independent decision points in one IC.
10 (VDD)	Positive supply	Single power rail for all comparators and outputs; decoupling capacitor required at Pin 10.
11 (4OUT)	Push-pull output, Comparator 4	Active-high/active-low CMOS output; sinks or sources up to 20 mA without external components.
12 (3OUT)	Push-pull output, Comparator 3	Directly drives logic inputs or LEDs; compatible with 3.3 V and 5 V MCU I/O thresholds.
13 (2OUT)	Push-pull output, Comparator 2	No pullup resistor needed - reduces BOM count and board area vs. open-collector alternatives.

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; higher supply current (500 µA typ); slower response (1.3 µs min but 30 µs typical at light loads).	Compatible in legacy designs where pullup resistors already exist; unsuitable for ultra-low-power or high-speed edge detection.	Select LM339DR only when cost is primary constraint and board space/power budget allow for added resistors and higher IDD.
TLC3702IPWR	Dual-channel version in same TSSOP-8 package; identical LinCMOS specs, half the channel count, 30% smaller footprint.	Preferred for space-constrained dual-threshold applications; requires two ICs for quad functionality.	Choose TLC3702IPWR when only two comparators are needed - saves 35% PCB area and maintains identical performance and reliability.

Compared with LM339DR and TLC3702IPWR, the TLC3704IPW uniquely delivers quad-channel micropower operation with integrated push-pull outputs in a compact TSSOP-14, enabling lower system power, faster response, and reduced component count in new designs targeting industrial and portable equipment.

FAQ

What is the operating temperature range specified for the TLC3704IPW?

The TLC3704IPW is characterized for operation from −40°C to +85°C, meeting industrial-grade environmental requirements. This range is validated across all electrical parameters including input offset voltage (≤7 mV), supply current (≤125 µA), and propagation delay (tPHL ≤ 3.5 µs), ensuring reliable performance in factory automation, outdoor sensors, and automotive cabin modules without thermal derating.

Does the TLC3704IPW require external pullup resistors on its outputs?

No, the TLC3704IPW does not require external pullup resistors because it features a push-pull CMOS output stage capable of actively sourcing and sinking current (±20 mA). 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. The TLC3704IPW maintains full logic-level compatibility with TTL and CMOS inputs across its entire operating range.

Can the TLC3704IPW operate from a 3.3 V supply?

Yes, the TLC3704IPW supports supply voltages from 3 V to 16 V, making it fully operational at 3.3 V. At 3.3 V, it delivers VOH ≥ 2.8 V and VOL ≤ 350 mV (tested at −40°C to 85°C), ensuring robust interfacing with 3.3 V microcontrollers. Its micropower design draws only 35–125 µA total supply current, preserving battery life in portable 3.3 V systems without compromising speed (tPLH ≈ 3.2 µs at 3.3 V).

How does the input common-mode voltage range of the TLC3704IPW compare to standard comparators?

The TLC3704IPW offers a rail-to-rail input common-mode range of 0 V to VDD − 1.5 V, exceeding many standard comparators that limit inputs to VDD − 1.5 V minimum or require level-shifting for ground-referenced signals. This allows direct sensing of signals at GND potential (e.g., current-sense amplifiers) or high-side voltages up to 14.5 V on a 16 V rail - critical for accurate battery monitoring and motor control feedback without external op-amps or dividers.

Is the TLC3704IPW pin-compatible with other packages of the TLC3704 family?

No, the TLC3704IPW (TSSOP-14) is not pin-compatible with D (SOIC-14), N (PDIP-14), or J (CDIP-14) variants of the TLC3704, despite sharing identical electrical functionality. Pin assignments differ between TSSOP and SOIC/PDIP/CDIP packages - specifically, the order of IN+/IN− and OUT pins is rearranged. Migration requires PCB layout revision; however, schematic symbol and netlist logic remain unchanged due to consistent functional mapping per channel.
