Texas Instruments TLV3704IDG4

Overview

TLV3704IDG4 from Texas Instruments is a quad nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-powered systems. It draws only 560 nA per channel, operates from 2.5 V to 16 V, supports input common-mode voltage up to VCC + 5 V, and is rated for –40°C to +125°C industrial temperature range.

For engineers reviewing the TLV3704IDG4 datasheet, TLV3704IDG4 pinout, TLV3704IDG4 application, or TLV3704IDG4 equivalent, this device is selected when quiescent current, rail-overvoltage tolerance, and guaranteed industrial-temperature operation are critical - especially in portable medical devices, security sensors, and handheld instrumentation where supply headroom and reverse-battery robustness matter.

Technical Context

The TLV3704IDG4 implements a precision nanopower architecture with fail-safe inputs capable of accepting voltages up to 16 V independent of VCC, enabling direct connection to unregulated sources or battery terminals. Its internal power-on-reset (POR) holds outputs low for ≤3 ms during power ramp-up, ensuring deterministic startup behavior.

Each of its four comparators features an over-the-rail input stage with <1 pA bias current in low common-mode region and ≤55 nA when inputs exceed VCC, plus push-pull output driving capability without external pull-ups. Propagation delay is 16 µs (typ.) at 50 mV overdrive with 10 pF load.

FAQ

What is the maximum input voltage allowed on TLV3704IDG4 pins?

The TLV3704IDG4 supports input voltages from –0.1 V to VCC + 5 V, with absolute maximum rating of ±20 V differential and up to 16 V on any input pin regardless of VCC. This overvoltage tolerance enables direct connection to battery terminals or unregulated sensor outputs without external clamping.

Does TLV3704IDG4 require external pull-up resistors on its outputs?

No. TLV3704IDG4 features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pull-up resistors. This reduces power consumption, component count, and board area - especially beneficial in battery-powered designs.

What is the propagation delay of TLV3704IDG4 at 5 V supply and 50 mV overdrive?

At VCC = 5 V and 50 mV input overdrive into a 10 pF load, TLV3704IDG4 exhibits 16 µs typical propagation delay for both high-to-low and low-to-high transitions. Delay increases to ~45 µs at 10 mV overdrive, supporting precise timing in wake-up and alert circuits.

Can TLV3704IDG4 operate from a 2.5 V supply across its full temperature range?

Yes. TLV3704IDG4 is fully specified from 2.5 V to 16 V supply voltage across its industrial temperature range (–40°C to +125°C). At 2.5 V, supply current remains ≤1000 nA per channel, and input common-mode range extends from –0.1 V to 7.5 V.

How does the power-on-reset (POR) function in TLV3704IDG4?

TLV3704IDG4 incorporates an internal POR circuit that holds all four outputs low for ≤3 ms after VCC crosses 1.5 V during power-up. This ensures deterministic initial state and prevents spurious logic transitions in downstream microcontrollers or latches during supply ramp-up.
