Product details
Overview
TLV3402CDGK from Texas Instruments is a dual-channel nanopower open-drain comparator with 470 nA per channel supply current, rail-to-rail input range (–0.1 V to VCC + 5 V), and operation from 2.5 V to 16 V supply. It features reverse battery protection up to 18 V and is specified for industrial temperature range (–40°C to +125°C), making it ideal for battery-powered medical sensors and wireless security system voltage monitoring.
For engineers reviewing the TLV3402CDGK datasheet, TLV3402CDGK pinout, TLV3402CDGK application, or TLV3402CDGK equivalent, key selection criteria include ultra-low quiescent current, input overvoltage tolerance beyond VCC, open-drain output compatibility with mixed-voltage logic, and VSSOP-8 packaging for space-constrained portable designs.
Technical Context
The TLV3402CDGK implements a CMOS input stage with differential pair architecture enabling –0.1 V to VCC + 5 V common-mode input range and 80 pA typical input bias current. Its open-drain output stage requires external pull-up and supports level-shifting across voltage domains without internal clamping diodes.
It operates in a single functional mode with no enable/disable control, drawing only 470 nA per channel at 25°C and maintaining stable performance across –40°C to +125°C. Propagation delay varies with overdrive (55 µs at 50 mV overdrive) and load capacitance, while low-level output voltage remains ≤80 mV at 50 µA sink current.
Key Specifications

|---|---|
| Supply Current | 470 nA per channel - enables multi-year battery life in coin-cell–powered devices |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - allows direct sensing of signals above supply rail (e.g., battery voltage monitoring) |
| Supply Voltage Range | 2.5 V to 16 V - supports single-supply operation from Li-ion to 12-V industrial rails |
| Input Offset Voltage | 250 µV (typ) - ensures accurate threshold detection in precision low-voltage sensing |

| 3 | 1IN+ | Noninverting input for channel 1 - supports rail-to-rail common-mode range including negative inputs |
| 4 | GND | Analog ground reference - must be connected to system ground plane for noise immunity |
| 5 | 2IN+ | Noninverting input for channel 2 - electrically isolated from channel 1; shares same GND reference |
| 6 | 2IN− | Inverting input for channel 2 - supports identical overvoltage tolerance as channel 1 |
| 7 | 2OUT | Open-drain output for channel 2 - independently configurable with separate pull-up |
| 8 | VCC | Positive supply rail - decoupling capacitor (0.01 µF ceramic + 10 µF electrolytic) required per layout guidelines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3402IDGKR | Same electrical specs but I-suffix industrial grade (–40°C to +125°C); identical VSSOP-8 package and pinout | Required for extended temperature operation where C-suffix (0°C to +70°C) is insufficient | Select TLV3402IDGKR when ambient operating temperature exceeds 70°C or full industrial qualification is mandated |
| TLV3602IDGKR | Higher speed (1.5 µs propagation delay), higher supply current (12 µA/ch), same VSSOP-8 package | Suitable for fast-response applications (e.g., motor overcurrent protection) where nanopower is secondary | Choose TLV3602IDGKR only when <100 µs response time is mandatory and battery life is not constrained |
Compared with TLV3402CDGK, TLV3402IDGKR offers identical nanopower performance with guaranteed operation at –40°C, while TLV3602IDGKR trades 25× higher current for 30× faster switching - making TLV3402CDGK optimal for energy-critical, slow-signal monitoring tasks.

FAQ
What is the maximum input voltage the TLV3402CDGK can tolerate relative to VCC?
The TLV3402CDGK supports an input common-mode range from –0.1 V to VCC + 5 V. This means either input (IN+ or IN–) can safely exceed the positive supply rail by up to 5 V without damage or latch-up, enabling direct high-side sensing in battery-monitoring circuits. Absolute maximum rating is VCC + 5 V or 20 V, whichever is smaller.
Does the TLV3402CDGK require external pull-up resistors on its outputs?
Yes, the TLV3402CDGK has open-drain CMOS outputs and requires external pull-up resistors on both 1OUT and 2OUT pins. The datasheet specifies performance with a 1-MΩ pull-up; values between 10 kΩ and 10 MΩ are usable depending on speed vs. power trade-offs. No internal pull-ups exist.
What temperature range is guaranteed for the TLV3402CDGK?
The TLV3402CDGK is rated for the commercial temperature range of 0°C to +70°C. For operation from –40°C to +125°C, the TLV3402IDGKR (I-suffix) variant must be used - it shares identical electrical specifications and VSSOP-8 packaging but is fully characterized across the extended industrial range.
Can the TLV3402CDGK operate from a 2.5-V supply?
Yes, the TLV3402CDGK is fully specified down to 2.5 V supply voltage across the commercial temperature range. At 2.5 V, it maintains 470 nA per channel supply current, 250 µV typical input offset voltage, and functional open-drain output behavior - making it suitable for single-cell LiFePO₄ or alkaline-powered devices.
Is the TLV3402CDGK pin-compatible with other comparators in the TLV340x family?
The TLV3402CDGK in VSSOP-8 (DGK) package is pin-compatible with TLV3402IDGKR and TLV3402CDR (SOIC-8), sharing identical pin functions (1OUT, 1IN−, 1IN+, GND, 2IN+, 2IN−, 2OUT, VCC). However, it is not pin-compatible with TLV3401 (SOT-23-5) or TLV3404 (TSSOP-14/SOIC-14) due to different channel count and package geometry.
