Texas Instruments TLV3404ID

Overview

TLV3404ID 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 delivers ultra-low power sensing in battery-critical systems such as portable medical monitors and wireless security sensors.

For engineers reviewing the TLV3404ID datasheet, TLV3404ID pinout, TLV3404ID application, or TLV3404ID 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 high-impedance pull-up networks in threshold-detection circuits.

Technical Context

The TLV3404ID implements four independent comparators in a single SOIC-14 package, each featuring an open-drain CMOS output stage requiring external pull-up for logic-level translation. Its input stage supports common-mode voltages beyond the positive rail-up to VCC + 5 V-enabling high-side voltage monitoring without level-shifting circuitry.

Designed for nanopower operation, the device maintains stable propagation delay (55–300 µs depending on overdrive) and low output leakage (<50 pA at 25°C) across its full 2.5 V–16 V supply range and industrial temperature span. Reverse battery protection up to 18 V adds robustness in field-deployed equipment.

FAQ

What is the maximum input voltage allowed on TLV3404ID inputs?

The TLV3404ID supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum input voltage limited to the smaller of 20 V or VCC + 5 V. This allows safe high-side sensing-for example, monitoring a 12-V rail using a 5-V supply-without external clamping or level-shifting components. The device also features reverse battery protection up to –18 V on VCC.

Does TLV3404ID require external pull-up resistors on its outputs?

Yes, TLV3404ID has open-drain CMOS outputs and requires external pull-up resistors to define the logic HIGH level. The datasheet specifies performance with a 1-MΩ pull-up; 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; higher resistance minimizes current but slows response-especially with capacitive loads.

What is the operating temperature range for TLV3404ID?

The TLV3404ID is rated for industrial operation from –40°C to +125°C. This is confirmed in the Recommended Operating Conditions table and supported by full electrical characterization across that range-including supply current, input offset voltage, and propagation delay. The "I-suffix" designation in the part number explicitly denotes this extended temperature grade.

Can TLV3404ID be used with a 2.5-V supply?

Yes, TLV3404ID is fully specified down to 2.5 V for C-suffix versions and 2.7 V for I-suffix versions. At 2.5 V, it maintains 470 nA typical supply current per channel and retains functional input common-mode range (–0.1 V to 7.5 V). Propagation delay increases slightly at lower supplies, but remains within datasheet limits-making it viable for single-cell LiFePO₄ or two-cell alkaline systems.

How does TLV3404ID handle input overvoltage conditions?

TLV3404ID tolerates input voltages up to VCC + 5 V without damage or phase reversal, thanks to internal input protection circuitry. This allows direct connection to signals exceeding the supply rail-such as battery voltage monitoring in automotive or solar applications. Absolute maximum ratings cap input voltage at 20 V or VCC + 5 V (whichever is smaller), and differential input voltage is limited to ±20 V.
