Product details
Overview
TLV3404CPWRG4 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 features 250 µV typical input offset voltage, 55–88 dB CMRR, and 5 µs output fall time - enabling ultra-low-power threshold detection in battery-constrained systems such as portable medical monitors and wireless security sensors.
For engineers reviewing the TLV3404CPWRG4 datasheet, TLV3404CPWRG4 pinout, TLV3404CPWRG4 application, or TLV3404CPWRG4 equivalent, key selection criteria include its 4-channel open-drain topology, TSSOP-14 package footprint, –40°C to +125°C industrial temperature rating, and compatibility with high-impedance pull-up networks for flexible logic-level interfacing.
Technical Context
The TLV3404CPWRG4 implements a precision comparator core with input stage biasing optimized for sub-µA quiescent current while maintaining 3 µV/°C offset drift and 80 pA input bias current. Its open-drain CMOS output stage requires external pull-up and supports bidirectional voltage translation between domains up to 16 V.
Designed for single-supply operation from 2.5 V to 16 V (or ±1.25 V to ±8 V dual supply), it delivers stable propagation delays - 55 µs low-to-high and 30 µs high-to-low at 50 mV overdrive - with thermal performance validated across –40°C to +125°C using RθJA = 120.8°C/W in PW (TSSOP-14) packaging.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3404IPWR | Same electrical specs and pinout; rated for –40°C to +125°C (I-suffix), identical TSSOP-14 package. | No functional difference - differs only in TI's internal marking and tape-and-reel packaging variant. | Select TLV3404IPWR when requiring guaranteed industrial-grade qualification documentation or alternate reel size. |
| TLV3404CDR | SOIC-14 package (8.65 mm × 3.91 mm); same electrical specs but higher RθJA = 83.8°C/W and commercial temp range (0°C to +70°C). | Suitable for cost-sensitive, non-extended-temp applications where board space is less constrained. | Choose TLV3404CDR for prototyping or consumer-grade products where thermal margin and footprint are secondary to procurement simplicity. |
Compared with TLV3404CPWRG4, TLV3404IPWR offers identical performance with formal industrial qualification, while TLV3404CDR trades thermal efficiency and temperature range for SOIC compatibility and lower unit cost in non-ruggedized designs.

FAQ
What is the maximum supply voltage for TLV3404CPWRG4?
The absolute maximum supply voltage for TLV3404CPWRG4 is 17 V, but recommended operation is limited to 2.5 V to 16 V. Exceeding 16 V risks violating absolute maximum ratings and may cause permanent damage, even if within the –40°C to +125°C temperature range. Always observe derating guidelines in TI's SLCS135B datasheet Section 7.1.
Does TLV3404CPWRG4 support rail-to-rail input operation?
Yes, TLV3404CPWRG4 supports true rail-to-rail input operation from –0.1 V to VCC + 5 V, allowing inputs to exceed the positive supply rail by up to 5 V. This capability enables direct high-side sensing without external level-shifting circuitry - a key advantage over conventional comparators with limited input ranges.
What pull-up resistor value is recommended for TLV3404CPWRG4 outputs?
A 1-MΩ pull-up resistor is specified in the TLV3404CPWRG4 datasheet for all electrical characteristics testing. This value balances output rise time, power dissipation (<1 µW at 5 V), and noise immunity. Lower values (e.g., 100 kΩ) improve speed but increase quiescent current; higher values (>10 MΩ) degrade noise margin and response time.
Is TLV3404CPWRG4 pin-compatible with other TLV340x variants?
TLV3404CPWRG4 is pin-compatible with TLV3404IPWR (same TSSOP-14 package and pinout) but not with TLV3404CDR (SOIC-14) or TLV3402 variants (8-pin). Pin mapping matches the TLV3404 family definition in Section 6 of SLCS135B - verify GND (Pin 11), VCC (Pin 4), and output/inverting/noninverting pin assignments before layout reuse.
Can TLV3404CPWRG4 operate from a dual supply?
Yes, TLV3404CPWRG4 supports dual-supply operation from ±1.25 V to ±8 V, as specified in Section 7.3 of the datasheet. When using dual supplies, the input common-mode range remains –0.1 V to VCC + 5 V relative to the negative rail, preserving high-side sensing capability even with split rails.
