Product details
Overview
TLV3704ID from Texas Instruments is a quad nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-constrained systems. It draws only 560 nA per channel at 2.7 V, supports 2.5–16 V single-supply operation, features –0.1 V to VCC + 5 V input common-mode range, and operates across –40°C to +125°C industrial temperature range.
For engineers reviewing the TLV3704ID datasheet, TLV3704ID pinout, TLV3704ID application, or TLV3704ID equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-grade operating conditions, and real-world use cases in portable medical devices, security sensors, handheld instrumentation, and battery monitoring circuits.
Technical Context
The TLV3704ID implements a rail-to-rail input stage with over-the-rail capability (up to VCC + 5 V), enabling direct high-side voltage monitoring without level-shifting. Its internal power-on-reset (POR) circuit holds outputs low for ≤3 ms during supply ramp-up, ensuring deterministic startup behavior in unregulated or brownout-prone systems.
Each of its four independent comparators uses a low-input-bias-current architecture (<80 pA typ), achieves 1–5 mV input hysteresis, and delivers fast propagation delays (16–45 µs at 50 mV overdrive) with push-pull output capable of sourcing/sinking ±50 µA while maintaining VOL < 80 mV and VOH > VCC – 450 mV across full temperature range.
Key Specifications

| Input offset voltage | 250 µV typical, 7 mV max over –40°C to +125°C - ensures reliable threshold detection under thermal stress |
| Propagation delay (high→low) | 16 µs typical at 50 mV overdrive - balances speed and power for low-frequency event detection |
| Output type | Push-pull CMOS - eliminates need for external pull-up resistors, reducing BOM count and standby leakage |

FAQ
What is the maximum input voltage allowed on TLV3704ID pins?
The TLV3704ID supports an input common-mode range from –0.1 V to VCC + 5 V, with absolute maximum rating of ±20 V differential and 0 V to VCC + 5 V (whichever is smaller) on any input pin. This allows safe monitoring of 12 V battery rails using a 5 V supply without external clamping or attenuation - a key capability confirmed in Section 6.1 and 7.4.1.2 of the TLV3704ID datasheet.
Does TLV3704ID require external pull-up resistors on its outputs?
No. TLV3704ID 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 system power consumption, saves PCB space, and simplifies design - a verified feature documented in Section 1 (Features) and Section 7.3.2 of the TLV3704ID datasheet.
What is the power-on reset behavior of TLV3704ID?
TLV3704ID incorporates an internal power-on-reset (POR) circuit that holds all four outputs low for up to 3 ms after VCC crosses 1.5 V during power-up. This ensures glitch-free startup and prevents false triggering in battery-powered systems - a function explicitly defined in Section 7.3.1.1 and Figure 7-1 of the TLV3704ID datasheet.
Can TLV3704ID operate from a 2.5 V supply across its full temperature range?
Yes. TLV3704ID is specified for 2.5 V to 16 V single-supply operation across –40°C to +125°C, with guaranteed performance including 560 nA typical supply current and 7 mV max input offset voltage. This is confirmed in Section 6.3 (Recommended Operating Conditions) and Section 6.7 (Electrical Characteristics) of the TLV3704ID datasheet.
How does TLV3704ID handle reverse battery connection?
TLV3704ID includes reverse-battery protection up to –20 V on the VCC pin, preventing damage during incorrect battery installation. Inputs remain functional and fail-safe even when VCC is unpowered or reversed - a feature detailed in Section 1 (Features) and Section 7.4.1.2 (Fail-Safe Inputs) of the TLV3704ID datasheet.
