Texas Instruments TLV3404CPWR

Overview

TLV3404CPWR 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 supports industrial temperature range (–40°C to +125°C) and is used in battery-powered medical sensors and wireless security systems for ultra-low-power threshold detection.

For engineers reviewing the TLV3404CPWR datasheet, TLV3404CPWR pinout, TLV3404CPWR application, or TLV3404CPWR equivalent, key selection criteria include quiescent current budget, input common-mode voltage headroom above VCC, open-drain output compatibility with external pull-up networks, and TSSOP-14 package suitability for space-constrained PCB layouts.

Technical Context

The TLV3404CPWR implements four independent high-impedance comparators with CMOS input stages and open-drain NMOS outputs. Its input stage operates beyond the positive rail by up to 5 V, enabling high-side sensing without level-shifting. Each channel draws only 470 nA at 25°C and maintains functionality down to 2.5 V supply.

Propagation delay varies with overdrive: tPLH = 55 µs and tPHL = 30 µs at 50 mV overdrive (VCC = 5 V, CL = 10 pF). Input offset voltage is 250 µV (typ), with 3 µV/°C drift, and differential input resistance exceeds 300 MΩ - critical for high-impedance sensor interfacing.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage for TLV3404CPWR?

The absolute maximum supply voltage for TLV3404CPWR is 17 V, but recommended operating range is 2.5 V to 16 V. Exceeding 16 V risks parametric degradation or reliability issues, even if within absolute max ratings. The device is fully specified across this 2.5–16 V range, including input common-mode and propagation delay performance.

Does TLV3404CPWR support rail-to-rail input operation?

Yes, TLV3404CPWR supports true rail-to-rail input operation from –0.1 V to VCC + 5 V. This means it can accurately compare signals below ground (e.g., –0.1 V) and up to 5 V above the positive supply - enabling high-side sensing without external level-shifting circuitry. Input bias current remains below 250 pA across this full range.

What pull-up resistor value is recommended for TLV3404CPWR outputs?

A 1-MΩ pull-up resistor is specified in the TLV3404CPWR datasheet for characterization and meets all published timing and VOL specifications. Lower values (e.g., 10 kΩ–100 kΩ) improve rise time but increase static current; higher values (>10 MΩ) reduce power but degrade noise immunity and propagation delay. For battery-critical designs, 1 MΩ delivers optimal trade-off between speed and quiescent current.

Can TLV3404CPWR operate from a 2.5 V supply at –40°C?

No - TLV3404CPWR (C-suffix) is specified for 0°C to +70°C operation. At 2.5 V, minimum operating temperature is 0°C. For –40°C to +125°C operation at 2.5 V, the I-suffix variant TLV3404IPWR must be used. The C-suffix version's recommended operating conditions explicitly limit low-temperature operation to 0°C, regardless of supply voltage.

Is TLV3404CPWR pin-compatible with other TSSOP-14 comparators?

TLV3404CPWR follows TI's standard quad comparator pinout for TSSOP-14 (PW package), matching TLV3404IPWR and TLV3704IPWR. However, TLV3704IPWR has push-pull outputs - substituting it for TLV3404CPWR requires removing external pull-ups and verifying logic polarity. No other manufacturer's TSSOP-14 quad comparators share identical pin functions without validation.
