Texas Instruments TLV3704IDRG4

Overview

TLV3704IDRG4 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 2.7 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 - ideal for portable medical devices and security sensors.

For engineers reviewing the TLV3704IDRG4 datasheet, TLV3704IDRG4 pinout, TLV3704IDRG4 application, or TLV3704IDRG4 equivalent, key selection criteria include its rail-overlapping input range, reverse-battery-protected inputs, propagation delay under 50 µs at 10 mV overdrive, and SOIC-14 package compatibility with standard PCB layouts.

Technical Context

The TLV3704IDRG4 implements a proprietary input stage enabling operation with inputs up to 5 V above VCC without damage, while maintaining sub-1 pA bias current in low common-mode regions and <14 nA near VCC. Its internal power-on-reset circuit holds outputs low for ≤3 ms during supply ramp-up, ensuring deterministic startup behavior in energy-harvesting and wake-on-event systems.

Each of its four independent comparators features push-pull CMOS output (no external pull-up required), reverse-battery protection up to 20 V, and hysteresis of 1–5 mV typical - enabling robust noise immunity in high-impedance sensor interfaces without added external components.

FAQ

What is the maximum input voltage allowed on TLV3704IDRG4 pins?

The TLV3704IDRG4 supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum input voltage limited to 20 V (per Absolute Maximum Ratings). This means inputs can safely exceed the positive supply rail by up to 5 V, enabling direct sensing of battery voltages or other signals above VCC without external clamping or level shifting. The device also withstands reverse-battery conditions up to –20 V on input pins.

Does TLV3704IDRG4 require external pull-up resistors on its outputs?

No, TLV3704IDRG4 does not require external pull-up resistors because it features a push-pull CMOS output stage. Each of its four outputs actively drives high (to within 80 mV of VCC) and low (to within 8 mV of GND) without needing external components. This reduces system power consumption, simplifies schematic design, and eliminates resistor-related drift or noise coupling - especially beneficial in ultra-low-power applications where every nanoamp counts.

What is the propagation delay of TLV3704IDRG4 at low overdrive levels?

At 10 mV input overdrive, the TLV3704IDRG4 exhibits a typical propagation delay of 45 µs for high-to-low transitions and 34 µs for low-to-high transitions (VCC = 2.7 V to 15 V, CL = 10 pF). These values increase slightly at temperature extremes (e.g., 80 µs max at 125°C), but remain stable across the full industrial temperature range. The delay is optimized for slow-varying signals such as battery voltage decay or temperature thresholds - not intended for high-speed digital signaling.

Can TLV3704IDRG4 operate with a 2.5 V supply?

TLV3704IDRG4 is specified for operation down to 2.7 V over the full industrial temperature range (–40°C to +125°C), and down to 2.5 V for commercial-grade variants. While some functionality may persist at 2.5 V, Texas Instruments guarantees performance only at ≥2.7 V for the I-suffix part. For reliable operation in low-voltage battery systems (e.g., single-cell LiFePO₄), design margins should assume 2.7 V minimum supply to ensure consistent propagation delay, output drive strength, and input offset stability.

How does the power-on-reset (POR) function behave in TLV3704IDRG4?

The TLV3704IDRG4 incorporates an internal power-on-reset circuit that holds all four outputs low for up to 3 ms after VCC crosses 1.5 V during power-up or brown-out recovery. This ensures deterministic initial state regardless of input conditions, preventing spurious logic transitions in downstream microcontrollers or latches. The POR activates automatically - no external components or configuration are needed - and is fully characterized across temperature and supply voltage variations.
