Product details
Overview
TLV3402CDG4 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 delivers ultra-low quiescent power for battery-critical sensing in portable medical devices and wireless security systems.
For engineers reviewing the TLV3402CDG4 datasheet, TLV3402CDG4 pinout, TLV3402CDG4 application, or TLV3402CDG4 equivalent, this page provides verified electrical parameters, thermal metrics, industrial-grade temperature support (–40°C to +125°C), VSSOP-8 package details, and real-world threshold-detection use cases - all confirmed against TI's SLCS135B revision January 2017 production data sheet.
Technical Context
The TLV3402CDG4 implements a rail-to-rail input stage with reverse-battery protection up to 18 V and open-drain CMOS output logic. Its input bias current is 80 pA typical at 25°C, and it maintains stable propagation delay (tPLH = 55 µs, tPHL = 30 µs at 50 mV overdrive) across 2.7 V–15 V supplies.
Designed for single-supply operation (2.5 V–16 V) or split-supply (±1.25 V–±8 V), the device supports wide common-mode voltage beyond rails and exhibits 55–88 dB CMRR depending on supply and input range - enabling reliable high-side voltage sense and low-power wake-up detection without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 470 nA per channel - enables >10-year battery life in coin-cell-powered sensors |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - supports high-side sensing above supply rail without clamping diodes |
| Supply Voltage Range | 2.5 V to 16 V single supply - compatible with Li-ion, alkaline, and industrial 12-V systems |
| Input Offset Voltage | 250 µV typical - ensures <1.25 mV error in 1.25-V threshold detection circuits |
| Propagation Delay | tPLH = 55 µs / tPHL = 30 µs at 50 mV overdrive - balances speed and nanopower trade-off for wake-up triggers |
| Operating Temperature | –40°C to +125°C (I-suffix grade) - qualified for automotive under-hood and industrial control environments |
| ESD Rating | ±2000 V HBM - robust handling during PCB assembly and field service |
Pinout & Package
TLV3402CDG4 is packaged in an 8-pin VSSOP (DGK) with body size 3.00 mm × 3.00 mm and 0.65-mm lead pitch. This thermally enhanced, surface-mount package supports high-density layouts and offers RθJA = 186.8°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Open-drain output for channel 1 - requires external pull-up; sinks up to 2 µA at 8 mV VOL |
| 2 | 1IN– | Inverting input, channel 1 - accepts signals down to –0.1 V, enabling ground-referenced comparisons |
| 3 | 1IN+ | Noninverting input, channel 1 - supports rail-to-rail common-mode range for flexible threshold placement |
| 4 | GND | Analog ground reference - must connect to low-impedance PCB ground plane to minimize noise coupling |
| 5 | 2IN+ | Noninverting input, channel 2 - electrically isolated from channel 1; shares same VCC and GND |
| 6 | 2IN– | Inverting input, channel 2 - independent signal path; no crosstalk specified between channels |
| 7 | 2OUT | Open-drain output for channel 2 - independently controllable; compatible with 1.8-V to 15-V pull-up rails |
| 8 | VCC | Positive supply pin - decoupling requires 0.01 µF ceramic + 10 µF electrolytic per layout guidelines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3402IDGKR | Same electrical specs; I-suffix rated for –40°C to +125°C (TLV3402CDG4 is C-suffix: 0°C to +70°C) | Required for automotive or industrial ambient environments exceeding 70°C | Select TLV3402IDGKR when full industrial temperature range validation is mandatory |
| TLV3602IDGKR | Higher supply current (600 nA), lower input offset (150 µV), faster propagation (tPLH = 25 µs), push-pull output | Used where faster response or rail-to-rail output swing without pull-up is needed | Choose TLV3602IDGKR only if speed or output drive strength outweighs 28% higher quiescent current |
Compared with TLV3402CDG4, TLV3402IDGKR extends operating temperature but retains identical pinout and quiescent power, while TLV3602IDGKR trades nanopower efficiency for speed and output flexibility - making TLV3402CDG4 optimal for cost-sensitive, battery-limited designs requiring guaranteed 0°C–70°C performance.

FAQ
What is the maximum supply voltage rating for TLV3402CDG4?
The absolute maximum supply voltage for TLV3402CDG4 is 17 V, though recommended operating conditions specify 2.5 V to 16 V. Exceeding 17 V risks permanent damage per TI's Absolute Maximum Ratings table. The device also features reverse-battery protection up to –18 V on VCC relative to GND, making TLV3402CDG4 resilient to incorrect power connections in field-deployed systems.
Does TLV3402CDG4 support rail-to-rail input operation?
Yes, TLV3402CDG4 supports rail-to-rail input operation with a common-mode range from –0.1 V to VCC + 5 V. This exceeds the supply rails, allowing direct high-side sensing (e.g., monitoring 12-V bus voltage with 5-V supply) without external attenuators or level shifters - a key advantage confirmed in Section 7.3 of the SLCS135B datasheet for TLV3402CDG4.
What package type is used for TLV3402CDG4?
TLV3402CDG4 uses the DGK package: an 8-pin VSSOP with 3.00 mm × 3.00 mm body size and 0.65-mm lead pitch. This thermally optimized surface-mount package delivers RθJA = 186.8°C/W and is distinct from SOIC (D) and PDIP (P) variants listed for other TLV3402 suffixes - confirmed in TI's Device Information table and Mechanical section of SLCS135B.
Can TLV3402CDG4 drive an LED directly?
No, TLV3402CDG4 cannot drive an LED directly. Its open-drain output is rated for 2 µA sink current at 8 mV VOL (typical), far below the 5–20 mA required for visible LEDs. It requires an external pull-up resistor and a discrete transistor or dedicated LED driver stage. This limitation is inherent to its nanopower architecture and is explicitly documented in the Electrical Characteristics table for IOZ and VOL parameters of TLV3402CDG4.
Is TLV3402CDG4 pin-compatible with TLV3402IDGKR?
Yes, TLV3402CDG4 and TLV3402IDGKR share identical VSSOP-8 (DGK) pinout, footprint, and electrical interface - differing only in temperature grade (C-suffix: 0°C to +70°C vs. I-suffix: –40°C to +125°C). No PCB changes are required when upgrading to the industrial-grade variant, and all timing, supply, and input/output specifications remain functionally identical per TI's Device Comparison Table in SLCS135B.
