Product details
Overview
TLV3402IP from Texas Instruments is a dual-channel nanopower open-drain comparator with 470 nA per channel supply current, –0.1 V to VCC + 5 V input common-mode range, and operation from 2.5 V to 16 V supply. It supports industrial temperature range (–40°C to +125°C) and is used in ultra-low-power threshold detection circuits for battery-powered instrumentation.
For engineers reviewing the TLV3402IP datasheet, TLV3402IP pinout, TLV3402IP application, or TLV3402IP equivalent, key selection criteria include quiescent current budget, rail-exceeding input range, open-drain output compatibility with external pull-up networks, and VSSOP-8 packaging for space-constrained portable designs.
Technical Context
The TLV3402IP implements a CMOS-input, open-drain output architecture optimized for nanopower operation without sacrificing input voltage range. Its input stage operates down to –0.1 V below ground and up to 5 V above VCC, enabling high-side sensing and reverse-battery-protected configurations.
Each comparator channel features independent inverting and noninverting inputs with 80 pA typical input bias current and 250 µV maximum input offset voltage at 25°C. Propagation delay is 55 µs (low-to-high) and 30 µs (high-to-low) under 50 mV overdrive with 1 MΩ pull-up and 10 pF load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3402IDGKR | VSSOP-8 package, same electrical specs, tape-and-reel packaging for automated assembly | Identical functional behavior; preferred for SMT production vs. tube-packaged TLV3402IP | Select TLV3402IDGKR for volume manufacturing; TLV3402IP suits prototyping and low-volume builds |
| TLV7012DRYR | Lower 360 nA supply current, but narrower 1.8 V–5.5 V supply range and no VCC+5 V input capability | Suitable only for 3.3 V systems with tight current budgets; cannot replace TLV3402IP in 12 V or high-side sensing roles | Choose TLV7012DRYR only if supply is ≤5.5 V and rail-exceeding input is not required |
Compared with TLV3402IDGKR, TLV3402IP offers identical performance in tube packaging for manual assembly, while TLV7012DRYR trades input voltage range and supply flexibility for marginal current reduction - making TLV3402IP the only option supporting 12 V systems and high-side sensing.

FAQ
What is the maximum supply voltage rating for TLV3402IP?
The absolute maximum supply voltage for TLV3402IP is 17 V, though recommended operating range is 2.5 V to 16 V. Exceeding 17 V risks permanent damage. The device also withstands reverse battery conditions up to –18 V on VCC relative to GND, making it suitable for consumer battery compartments where polarity reversal may occur.
Does TLV3402IP support rail-to-rail input operation?
TLV3402IP does not provide rail-to-rail input - instead, it supports an extended common-mode range from –0.1 V to VCC + 5 V. This means inputs can go 5 V above the positive supply or 0.1 V below ground, enabling high-side sensing and eliminating level-shifters in many applications where true rail-to-rail is unnecessary.
What pull-up resistor value is specified for TLV3402IP open-drain outputs?
TI specifies TLV3402IP performance with a 1 MΩ pull-up resistor to VCC. This value balances output rise time, power consumption, and noise immunity. Using smaller values improves speed but increases static current; larger values reduce current but degrade propagation delay and noise margin - especially at elevated temperatures.
Is TLV3402IP qualified for automotive applications?
TLV3402IP is rated for industrial temperature range (–40°C to +125°C) and meets JEDEC JESD22-A114 reliability standards, but it is not AEC-Q200 qualified. For automotive cabin or under-hood use, TI recommends the AEC-Q200–qualified TLV3402QDRQ1 variant - TLV3402IP is appropriate for industrial, medical, and commercial-grade systems meeting IPC-610 Class 2/3 requirements.
Can TLV3402IP operate from a 2.5 V supply across the full temperature range?
Yes - TLV3402IP operates from 2.5 V at 0°C to +70°C (C-suffix) and from 2.7 V at –40°C to +125°C (I-suffix). The TLV3402IP part number corresponds to the industrial-grade version, so its guaranteed minimum supply is 2.7 V across –40°C to +125°C. At 2.5 V, operation is not specified outside 0°C to +70°C.
