Product details
Overview
TLV3404CPW 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 supply. It delivers ultra-low power sensing in battery-critical systems such as portable medical monitors and wireless security sensors.
For engineers reviewing the TLV3404CPW datasheet, TLV3404CPW pinout, TLV3404CPW application, or TLV3404CPW equivalent, key selection criteria include quiescent current budgeting, input overvoltage tolerance, open-drain output compatibility with mixed-voltage logic, and thermal performance in TSSOP-14 packaging for high-density PCB layouts.
Technical Context
The TLV3404CPW implements a CMOS input stage with differential pair architecture enabling –0.1 V to VCC + 5 V common-mode input range - exceeding both supply rails. Its open-drain output stage requires external pull-up and supports level-shifting across voltage domains up to 16 V.
Specified across –40°C to +125°C industrial temperature range, it maintains 470 nA typical supply current per channel at 2.7 V and exhibits 250 µV input offset voltage with 3 µV/°C drift. Propagation delay ranges from 30 µs (50 mV overdrive) to 300 µs (2 mV overdrive) under 10 pF load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3404CDR | SOIC-14 package (8.65 mm × 3.91 mm); higher RθJA = 83.8 °C/W; same electrical specs | Better thermal performance in convection-cooled industrial enclosures; larger footprint limits high-density layouts | Select TLV3404CDR when board space permits and thermal margin is critical; TLV3404CPW preferred for compact portable designs |
| TLV3604IPW | Higher speed (1.5 µs propagation delay), 1.2 µA supply current, rail-to-rail output, same TSSOP-14 package | Replaces TLV3404CPW only where faster response justifies 2.5× higher current draw - unsuitable for multi-year battery life | Choose TLV3604IPW only if system requires sub-microsecond timing; TLV3404CPW remains optimal for true nanopower constraints |
Compared with TLV3404CDR and TLV3604IPW, the TLV3404CPW uniquely balances ultra-low 470 nA quiescent current, VCC + 5 V input overvoltage tolerance, and compact TSSOP-14 packaging - making it the sole choice for space-constrained, multi-year battery applications requiring robust input handling.

FAQ
What is the maximum input voltage the TLV3404CPW can tolerate beyond its supply rail?
The TLV3404CPW supports an input common-mode range up to VCC + 5 V, meaning it tolerates signals 5 V above the positive supply rail without damage or phase reversal. This capability is explicitly specified in the Recommended Operating Conditions table and validated across –40°C to +125°C. For example, with VCC = 3.3 V, inputs may safely reach 8.3 V - eliminating external clamping components in high-side sensing circuits using the TLV3404CPW.
Does the TLV3404CPW require external pull-up resistors on all four outputs?
Yes, the TLV3404CPW features open-drain outputs on all four channels, mandating external pull-up resistors for proper logic-level generation. The datasheet specifies performance with a 1 MΩ pull-up to VCC; values between 10 kΩ and 10 MΩ are usable depending on speed vs. power trade-offs. Lower resistance improves rise time but increases static current - critical to consider when optimizing total system power for the TLV3404CPW.
What is the operating temperature range for the TLV3404CPW part number?
The TLV3404CPW is rated for the industrial temperature range of –40°C to +125°C, as confirmed by the "I-suffix versions" row in Section 7.3 (Recommended Operating Conditions) and thermal characterization data in Section 7.6. This specification applies to the PW (TSSOP-14) package variant and is validated across all electrical parameters including supply current, offset voltage, and propagation delay - ensuring reliable operation in automotive, industrial, and outdoor deployments using the TLV3404CPW.
Can the TLV3404CPW be used with dual-supply configurations?
Yes, the TLV3404CPW supports dual-supply operation from ±1.25 V to ±8 V, as stated in Section 8.3.1 and Table 5 (Device Comparison Table). In dual-supply mode, the input common-mode range extends from –0.1 V to VCC + 5 V relative to the negative rail, preserving its overvoltage capability. This makes the TLV3404CPW suitable for legacy bipolar sensor interfaces while maintaining nanopower efficiency - a key differentiator versus standard comparators in the TLV3404CPW family.
How does reverse battery protection work on the TLV3404CPW?
The TLV3404CPW incorporates internal reverse-battery protection that withstands –18 V applied to VCC with respect to GND, per Absolute Maximum Ratings (Section 7.1). This protection prevents destructive current flow during incorrect battery installation in portable devices. Unlike external diode solutions, this feature adds no forward voltage drop or leakage - preserving accuracy and battery life in systems relying on the TLV3404CPW for critical monitoring functions.
