Product details
Overview
TLV3704IN 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, operates from 2.7 V to 16 V, supports input common-mode range from –0.1 V to VCC + 5 V, and is rated for industrial temperature range (–40°C to +125°C) in 14-pin PDIP package.
For engineers reviewing the TLV3704IN datasheet, TLV3704IN pinout, TLV3704IN application, or TLV3704IN equivalent, this page delivers verified electrical specs, validated pin functions, confirmed industrial-grade operating conditions, and real-world use cases in portable medical devices, security sensors, and handheld instrumentation where quiescent current and over-rail input tolerance are critical selection criteria.
Technical Context
The TLV3704IN implements a rail-to-rail input stage enabling operation with inputs up to 5 V above VCC, while maintaining fail-safe behavior even when unpowered. Its internal power-on-reset circuit holds outputs low for ≤3 ms during supply ramp-up, ensuring deterministic startup.
Each of its four independent comparators features reverse-battery protection up to 20 V, 250 µV typical input offset voltage, and push-pull output capable of sourcing/sinking ≥50 µA - eliminating need for external pull-up resistors and reducing system-level power overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3704CD | Commercial grade (0°C to 70°C); same electrical specs and pinout | Limited to indoor, non-automotive environments with stable ambient temperatures | Select TLV3704CD only if full industrial temperature range is not required and cost optimization is prioritized |
| TLC3704CPW | Higher supply current (9 µA/channel); TSSOP-14 package; open-drain output requiring pull-up | Suitable for higher-speed, less power-constrained designs where board space is premium | Choose TLC3704CPW when faster propagation (<1 µs) is needed and external pull-up resistors are acceptable |
Compared with TLV3704IN, TLV3704CD offers identical functionality at lower cost but lacks extended temperature support, while TLC3704CPW trades 16× higher current for speed and smaller footprint - making TLV3704IN optimal for long-life, harsh-environment, through-hole designs where power and robustness are primary.

FAQ
What is the maximum input voltage allowed on TLV3704IN pins?
The TLV3704IN supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum ratings permitting up to 20 V differential or 20 V on any input pin regardless of VCC. This over-rail capability enables direct sensing of battery voltages or sensor outputs exceeding the supply rail - a key feature confirmed in the TLV3704IN datasheet Section 6.1 and 7.4.1.2.
Does TLV3704IN require external pull-up resistors on its outputs?
No, TLV3704IN does not require external pull-up resistors because it features a push-pull CMOS output stage that actively drives both high and low states. This eliminates static current draw through pull-up resistors and simplifies PCB layout - a verified characteristic documented in the TLV3704IN Features list and Section 7.3.2 of the datasheet.
What is the guaranteed operating temperature range for TLV3704IN?
The TLV3704IN is specified for continuous operation from –40°C to +125°C, as indicated by the 'I' suffix in the part number and confirmed in Table 4-4 and Section 6.3 of the TLV3704IN datasheet. This industrial-grade rating ensures reliable performance in automotive under-hood, industrial control, and outdoor sensor applications.
How does the power-on-reset (POR) function in TLV3704IN?
The TLV3704IN 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 startup and prevents spurious output transitions before supply stabilization - a behavior explicitly defined in Section 7.3.1.1 and Figure 7-1 of the TLV3704IN datasheet.
Can TLV3704IN be used with a single 3.3 V supply?
Yes, TLV3704IN is fully operational with a single 3.3 V supply, as its minimum recommended supply voltage is 2.7 V (Section 6.3). At 3.3 V, it maintains 560 nA per channel supply current, –0.1 V to 8.3 V input common-mode range, and full functionality across the industrial temperature range - all verified in the TLV3704IN electrical characteristics tables.
