Product details
Overview
TLV3404IPWR 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 from 2.5 V to 16 V. It delivers ultra-low quiescent power for battery-critical applications such as portable medical sensors and wireless security system voltage monitoring.
For engineers reviewing the TLV3404IPWR datasheet, TLV3404IPWR pinout, TLV3404IPWR application, or TLV3404IPWR equivalent, key selection criteria include its 4-channel open-drain output architecture, –40°C to +125°C industrial temperature rating, 250 µV input offset voltage, and compatibility with 1 MΩ pull-up resistors in threshold-detection circuits.
Technical Context
The TLV3404IPWR implements a CMOS-input, open-drain output stage optimized for nanopower operation without sacrificing input voltage range. Its input stage supports common-mode voltages up to 5 V beyond VCC, enabling high-side sensing in systems with floating references or reverse-battery protection requirements.
Each of the four independent comparator channels operates with matched propagation delay characteristics (tPLH = 55 µs, tPHL = 30 µs at 50 mV overdrive) and exhibits low input bias current (80 pA typ) and high differential input resistance (300 MΩ), making it suitable for high-impedance sensor interface applications.

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) instead of TSSOP-14 | SOIC offers easier hand-soldering and higher thermal mass; lower board density than TSSOP | Select TLV3404IDR for prototyping or low-volume production where manual assembly or thermal stability outweighs size constraints |
| TLV3604IPWR | Higher speed (tPHL = 1.2 µs), 1.2 µA supply current, rail-to-rail output - not open-drain | Requires redesign of pull-up network; unsuitable for wired-OR or level-shifted buses | Choose TLV3604IPWR only when nanosecond-level response is mandatory and open-drain functionality is unnecessary |
Compared with TLV3404IPWR, TLV3404IDR provides identical performance in a larger, more manufacturable package, while TLV3604IPWR trades 25× higher quiescent current for 60× faster switching - making TLV3404IPWR optimal for energy-constrained, multi-channel threshold detection.

FAQ
What is the maximum supply voltage rating for TLV3404IPWR?
The absolute maximum supply voltage for TLV3404IPWR is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation above 16 V risks permanent damage, and the device is fully characterized only within the 2.5–16 V range across its –40°C to +125°C temperature span. Always observe derating guidelines for long-term reliability.
Does TLV3404IPWR support rail-to-rail input operation?
Yes, TLV3404IPWR supports an input common-mode range from –0.1 V to VCC + 5 V, which exceeds rail-to-rail by 5 V on the high side. This allows direct connection to signals referenced above VCC - such as high-side current-sense amplifiers or reverse-battery protected supplies - without external level-shifting components.
Can TLV3404IPWR outputs be wire-OR'd together?
Yes, all four outputs of TLV3404IPWR are open-drain CMOS and can be connected to a shared pull-up resistor to implement wired-OR logic. This configuration is commonly used for fault-bus architectures where any comparator asserting low indicates a system-level alert condition - a key design advantage over push-pull output comparators.
What is the typical input offset voltage of TLV3404IPWR?
The typical input offset voltage of TLV3404IPWR is 250 µV at 25°C, with a maximum of 3600 µV over the full –40°C to +125°C temperature range. This specification enables accurate threshold detection in low-voltage applications such as battery voltage monitoring at 3.0 V or sensor zero-crossing detection in millivolt-range transducers.
Is TLV3404IPWR qualified for automotive applications?
TLV3404IPWR is not AEC-Q200 qualified, but its –40°C to +125°C industrial temperature rating, reverse-battery protection (–18 V tolerance), and robust ESD performance (±2000 V HBM) make it suitable for non-safety-critical automotive cabin modules - including infotainment power supervision, seat occupancy sensor interfaces, and ambient light control subsystems.
