Product details
Overview
TLV3402CDGKRG4 from Texas Instruments is a dual 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. It delivers ultra-low quiescent power for battery-critical sensing in portable medical devices and wireless security systems.
For engineers reviewing the TLV3402CDGKRG4 datasheet, TLV3402CDGKRG4 pinout, TLV3402CDGKRG4 application, or TLV3402CDGKRG4 equivalent, key selection criteria include guaranteed 470 nA supply current at 25°C, industrial-grade –40°C to +125°C operation, open-drain output compatibility with external pull-up networks, and VSSOP-8 package footprint constraints.
Technical Context
The TLV3402CDGKRG4 implements a rail-to-rail input stage with reverse-battery protection up to 18 V and input overvoltage tolerance of 5 V beyond VCC. Its open-drain CMOS output requires external pull-up for logic-level translation across voltage domains.
Designed for single-supply (2.5–16 V) or split-supply (±1.25 V to ±8 V) operation, it maintains 250 µV typical input offset voltage and 55–88 dB common-mode rejection across 0–15 V input range - enabling precision threshold detection without external trimming.

| 3 | 1IN+ | Noninverting input for channel 1 - supports rail-to-rail common-mode range down to –0.1 V |
| 4 | GND | Analog ground reference - must connect to low-impedance PCB ground plane |
| 5 | 2IN+ | Noninverting input for channel 2 - electrically isolated from channel 1 inputs |
| 6 | 2IN– | Inverting input for channel 2 - supports independent threshold comparison |
| 7 | 2OUT | Open-drain output for comparator channel 2 - independently controllable from channel 1 |
| 8 | VCC | Positive supply pin - decoupling capacitor (0.01 µF ceramic + 10 µF electrolytic) required |

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 (C-suffix TLV3402CDGKRG4 is 0°C to +70°C) | Required for extended-temperature industrial deployments where ambient exceeds 70°C | Select TLV3402IDGKR when operating above 70°C ambient or requiring full industrial qualification |
| TLV7012DBVR | Lower supply current (360 nA), but narrower input range (0 V to VCC – 0.1 V) and no reverse-battery protection | Suitable only for low-voltage, single-rail applications without overvoltage or reverse-polarity risk | Choose TLV7012DBVR only if supply is strictly regulated ≤5.5 V and reverse-battery immunity is unnecessary |
Compared with TLV3402CDGKRG4, TLV3402IDGKR offers identical performance with extended temperature rating, while TLV7012DBVR trades robustness for lower quiescent current - making TLV3402CDGKRG4 optimal for cost-sensitive commercial designs needing rail-overvoltage tolerance and 70°C max ambient operation.

FAQ
What is the maximum supply voltage for TLV3402CDGKRG4?
The absolute maximum supply voltage for TLV3402CDGKRG4 is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation beyond 16 V risks permanent damage, and the device is fully specified only within the 2.5–16 V range across its temperature grade. The TLV3402CDGKRG4 also features reverse-battery protection up to –18 V on VCC relative to GND.
Does TLV3402CDGKRG4 support rail-to-rail input operation?
Yes, TLV3402CDGKRG4 supports rail-to-rail input operation with a common-mode range from –0.1 V to VCC + 5 V. This allows the inputs to operate below ground (e.g., for differential sensing) and up to 5 V above the positive supply - enabling high-side sensing without level-shifting circuitry. The specification is verified across the full –40°C to +125°C range for I-suffix variants; TLV3402CDGKRG4 (C-suffix) is characterized from 0°C to +70°C.
What pull-up resistor value is recommended for TLV3402CDGKRG4 outputs?
A 1-MΩ pull-up resistor is used in all electrical characterization tests for TLV3402CDGKRG4 and is recommended for optimal balance of output voltage swing, power efficiency, and propagation delay. Lower values increase power dissipation and reduce battery life; higher values degrade rise time and noise immunity. The TLV3402CDGKRG4 open-drain outputs require this external resistor to establish logic-high levels compatible with downstream logic families.
Is TLV3402CDGKRG4 pin-compatible with other TLV340x variants?
TLV3402CDGKRG4 in VSSOP-8 (DGK) is pin-compatible with TLV3402 in SOIC-8 (D) and PDIP-8 (P) packages for pins 1–8, sharing identical pin functions: 1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VCC. However, mechanical dimensions, thermal performance, and board layout requirements differ significantly between VSSOP and SOIC/PDIP - requiring separate footprint validation.
What is the input offset voltage specification for TLV3402CDGKRG4?
The TLV3402CDGKRG4 has a typical input offset voltage of 250 µV at 25°C, with a maximum of 3600 µV over the full 0°C to +70°C operating range. This parameter is measured with VIC = VCC/2, RS = 50 Ω, and RP = 1 MΩ. The low offset enables precise threshold detection - for example, reliable 1.25-V reference comparison without trimming - and drift is specified at 3 µV/°C.
