Product details
Overview
TLV3404IPW from Texas Instruments is a quad nanopower open-drain comparator with 470 nA per channel supply current, rail-to-rail input range (–0.1 V to VCC + 5 V), and operation across 2.5 V to 16 V supply. It delivers ultra-low quiescent power for battery-critical systems such as portable medical sensors and wireless security nodes.
For engineers reviewing the TLV3404IPW datasheet, TLV3404IPW pinout, TLV3404IPW application, or TLV3404IPW equivalent, key selection factors include its 4-channel open-drain output architecture, industrial-grade temperature support (–40°C to +125°C), and compatibility with 14-pin TSSOP packaging for space-constrained PCB layouts.
Technical Context
The TLV3404IPW implements four independent high-impedance comparators sharing a common VCC and GND, each featuring an open-drain CMOS output stage requiring external pull-up. Its input stage supports common-mode voltages beyond the positive rail-up to VCC + 5 V-enabling high-side sensing without level-shifting circuitry.
Designed for nanopower operation, the device maintains stable propagation delay (tPLH = 55 µs typical at 50 mV overdrive) and low input bias current (80 pA typical) across –40°C to +125°C, making it suitable for long-life, unattended sensor monitoring applications where supply current dominates system energy budget.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3404IDR | Same electrical specs; SOIC-14 package (8.65 mm × 3.91 mm), higher RθJA (83.8°C/W) | Better thermal dissipation in convection-cooled boards; less compact than TSSOP | Select when board layout prioritizes ease of hand-soldering or legacy footprint compatibility |
| TLV3404IPWR | Identical specs and TSSOP-14 package; tape-and-reel packaging only (no tube option) | Optimized for high-volume SMT production; same PCB footprint and thermal behavior | Select for automated assembly lines requiring reel-fed placement |

FAQ
What is the maximum supply voltage rating for TLV3404IPW?
The absolute maximum supply voltage for TLV3404IPW is 17 V, though recommended operating conditions specify 2.5 V to 16 V. Exceeding 17 V risks permanent damage. The device also features reverse battery protection up to –18 V on VCC relative to GND, safeguarding against incorrect installation in battery-powered designs. Always operate within the 2.5–16 V range for guaranteed parametric performance across temperature.
Does TLV3404IPW support rail-to-rail input operation?
Yes, TLV3404IPW supports a true rail-to-rail input common-mode range of –0.1 V to VCC + 5 V. This means inputs can safely exceed the positive supply rail by up to 5 V, enabling direct high-side sensing without external level-shifting components. The specification applies across the full industrial temperature range (–40°C to +125°C) and is verified in TI's Electrical Characteristics table under VICR parameter.
What pull-up resistor value is specified for TLV3404IPW open-drain outputs?
TI specifies TLV3404IPW performance-including propagation delay, VOL, and switching characteristics-with a 1-MΩ pull-up resistor to VCC. Using this value ensures compliance with datasheet timing and voltage parameters. Lower values reduce rise time but increase static current; higher values improve power efficiency but degrade speed and noise immunity. For 5-V operation, 1 MΩ yields ~5 µA standby current per active output.
Is TLV3404IPW qualified for automotive applications?
TLV3404IPW is not AEC-Q200 qualified, but its I-suffix industrial temperature rating (–40°C to +125°C), reverse battery protection (–18 V), and robust ESD ratings (±2000 V HBM) make it suitable for non-safety-critical automotive subsystems such as cabin sensors, body control modules, and infotainment power supervision. For ASIL-B/C applications, consult TI's automotive-grade alternatives like TLV3404QDRQ1.
How does TLV3404IPW handle input overvoltage beyond VCC + 5 V?
TLV3404IPW limits absolute maximum input voltage to the smaller of 20 V or VCC + 5 V per Absolute Maximum Ratings. Inputs exceeding VCC + 5 V (or 20 V total) risk damaging internal ESD structures. To protect against transient overvoltage, TI recommends external clamping diodes or series current-limiting resistors when interfacing with signals that may exceed this bound-especially in noisy industrial or automotive environments.
