Texas Instruments TLV3404IDG4

Overview

TLV3404IDG4 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 V_CC + 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 ultra-low-power battery monitoring and threshold detection circuits.

For engineers reviewing the TLV3404IDG4 datasheet, TLV3404IDG4 pinout, TLV3404IDG4 application, or TLV3404IDG4 equivalent, key selection criteria include quiescent current budget, input common-mode voltage headroom beyond V_CC, open-drain output compatibility with external pull-up networks, and thermal performance in SOIC-14 packaging.

Technical Context

The TLV3404IDG4 implements a CMOS-input, open-drain output architecture optimized for nanopower operation without sacrificing input voltage range. Its input stage operates with –0.1 V to V_CC + 5 V common-mode range and exhibits 80 pA typical input bias current at 25°C.

Each of its four independent comparators features propagation delays of 55 µs (low-to-high) and 30 µs (high-to-low) at 50 mV overdrive, with 5 µs fall time and 2.5 V to 16 V single-supply support - enabling direct integration into 3.3 V and 5 V sensor interface rails.

FAQ

What is the maximum input voltage allowed on TLV3404IDG4 pins?

The TLV3404IDG4 supports an input common-mode voltage range of –0.1 V to V_CC + 5 V, with absolute maximum rating of V_CC + 5 V (or 20 V, whichever is smaller). This allows direct high-side sensing without external clamping, and reverse-battery protection up to –18 V on V_CC. Exceeding these limits risks permanent damage.

Does TLV3404IDG4 require external pull-up resistors on its outputs?

Yes, TLV3404IDG4 has open-drain CMOS outputs and requires external pull-up resistors on each OUT pin. The datasheet specifies performance with 1 MΩ pull-ups; lower values improve rise time but increase static current, while higher values degrade switching speed. TLV3404IDG4 cannot drive logic-high levels without them.

Can TLV3404IDG4 operate from a 1.8 V supply?

No, TLV3404IDG4 has a minimum recommended supply voltage of 2.5 V (2.7 V over full industrial temperature range). At 1.8 V, it will not function reliably - input stage biasing fails and propagation delay becomes undefined. For 1.8 V systems, consider TLV3604IDR or TLV7014 instead.

How many independent comparators does TLV3404IDG4 contain?

TLV3404IDG4 contains four fully independent comparators in a single SOIC-14 package. Each has dedicated IN+, IN–, and OUT pins with no shared internal nodes - enabling simultaneous monitoring of four separate analog thresholds without crosstalk or timing interaction.

Is TLV3404IDG4 pin-compatible with other TLV340x family members?

No - TLV3404IDG4 (SOIC-14) is not pin-compatible with TLV3401 (SOT-23-5 or SOIC-8) or TLV3402 (SOIC-8/VSSOP-8). Pin count, pin assignment, and package dimensions differ across the TLV340x family. Direct substitution requires PCB redesign; only TLV3404 variants (e.g., TLV3404IPW, TLV3404IN) share identical pinout.
