Product details
Overview
NC7WP00K8X from onsemi is a dual 2-input NAND gate IC designed for ultra-low-power logic in space-constrained applications. It operates across 0.9 V to 3.6 V supply, delivers 2.1 ns propagation delay at 3.3 V (typ), tolerates input/output voltages up to 3.6 V independent of VCC, supports IOFF partial power-down protection, and drives ±2.6 mA at 3.3 V - enabling use in battery-powered IoT sensors and portable interface logic.
For engineers reviewing the NC7WP00K8X datasheet, pinout, applications, or equivalent options, key selection criteria include its sub-1V operation capability, overvoltage-tolerant I/O, low dynamic power (CPD = 6.0 pF), and US8 package compatibility with high-density PCB layouts.
Technical Context
The NC7WP00K8X implements two independent NAND gates in a single monolithic CMOS structure using onsemi's TinyLogic ULP-A process. Its IOFF feature disables output leakage during power-down states, while overvoltage tolerance allows interfacing with higher-voltage domains without level shifters.
Propagation delay scales predictably with VCC (e.g., 40.7 ns at 0.9 V, 2.1 ns at 3.3 V) under 10 pF load, and input thresholds are ratio-based (VIH = 0.65×VCC, VIL = 0.35×VCC) across 1.1–3.6 V, ensuring robust noise margins in mixed-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct integration with 1.2 V, 1.8 V, 2.5 V, and 3.3 V rails without regulators |
| tPD (Typ) | 2.1 ns at VCC = 3.3 V, CL = 10 pF - supports >200 MHz toggle rates in low-load logic paths |
| IOFF Leakage | ≤0.5 µA at VCC = 0 V - prevents back-powering and signal corruption during partial system shutdown |
| Input/Output Voltage Tolerance | Up to 3.6 V regardless of VCC - eliminates need for external clamping diodes when interfacing with 3.3 V peripherals |
| Drive Strength | ±2.6 mA at VCC = 3.3 V - sufficient to drive multiple 74LVC inputs or short PCB traces without buffering |
| Power Dissipation Cap. | CPD = 6.0 pF - enables accurate no-load dynamic power estimation: PD = 6.0×VCC²×f |
| Operating Temp | −40 °C to +85 °C - qualified for industrial ambient environments including automotive cabin electronics |
Pinout & Package
NC7WP00K8X is packaged in an 8-pin US8 (SOIC-8 variant, case 846AN) surface-mount package measuring 2.1 mm × 2.0 mm × 0.55 mm, with gull-wing leads and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 (Y2) | Output of Gate 2 | Active-drive CMOS output; sinks/sources up to ±2.6 mA at 3.3 V |
| 4 (GND) | Ground Reference | Primary return path for all internal logic and I/O currents |
| 5 (A2) | Input of Gate 2 | Independent input for second NAND gate; no crosstalk with Gate 1 |
| 6 (B2) | Input of Gate 2 | Second input for second NAND function; fully decoupled from Gate 1 |

| 8 (VCC) | Positive Supply | Single supply rail powering both gates; IOFF active when VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-voltage operation | Functional down to 0.9 V VCC - enables direct connection to coin-cell or energy-harvesting power sources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G00DPWR | Wider VCC range (1.65–5.5 V); higher drive (±24 mA); no IOFF or sub-1V operation | Better suited for 5 V legacy interfaces; unsuitable for <1.2 V systems or partial power-down scenarios | Select when interfacing with 5 V logic or requiring higher fanout; avoid for energy-harvesting or battery-critical designs |
| 74AUP2G00GW,125 | Similar 0.8–3.6 V range and IOFF; slightly slower tPD (2.5 ns @ 3.3 V); same US8 package | Nearly drop-in replacement; marginally higher CPD (8.5 pF) increases dynamic power at high frequency | Valid alternative where 0.4 ns speed penalty is acceptable and NXP sourcing is preferred |
Compared with SN74LVC2G00DPWR and 74AUP2G00GW,125, the NC7WP00K8X uniquely supports 0.9 V operation and guarantees IOFF below 0.5 µA - critical for zero-power-state integrity in always-on sensor nodes and medical wearables.

FAQ
What is the minimum operating voltage for NC7WP00K8X?
The NC7WP00K8X is fully specified down to 0.9 V VCC, with functional operation confirmed across −40 °C to +85 °C at this rail. At 0.9 V, propagation delay increases to 40.7 ns (CL = 10 pF), and drive strength reduces proportionally - making it ideal for energy-harvesting or coin-cell-powered systems where ultra-low quiescent current and sub-1V compatibility are essential. The NC7WP00K8X maintains valid logic thresholds (VIH = 0.5 V, VIL = 0.5 V) even at minimum VCC.
Does NC7WP00K8X support partial power-down mode?
Yes, the NC7WP00K8X features IOFF circuitry that actively disables output drivers when VCC = 0 V, limiting I/O leakage to ≤0.5 µA. This prevents back-powering of upstream or downstream circuits during system sleep or modular power gating - a critical capability for battery-backed subsystems and hot-plug interfaces. The NC7WP00K8X achieves this without external enable pins or configuration registers, relying solely on VCC presence.
What package type is used for NC7WP00K8X?
The NC7WP00K8X uses the US8 package (case 846AN): an 8-pin, gull-wing, surface-mount outline measuring 2.1 mm × 2.0 mm × 0.55 mm with 0.65 mm lead pitch. It is JEDEC-compliant, moisture-sensitivity Level 1, and compatible with standard reflow soldering. This package differs from the MicroPak (UQFN8) variant NC7WP00L8X, which uses a 1.6 mm × 1.6 mm, 0.5 mm pitch land-grid array.
Can NC7WP00K8X interface directly with 3.3 V logic while powered from 1.8 V?
Yes - the NC7WP00K8X inputs and outputs are overvoltage tolerant up to 3.6 V regardless of VCC, allowing safe connection to 3.3 V buses while operating from a 1.8 V supply. No external level shifters or clamping diodes are required. This capability is verified per maximum ratings (VIN, VOUT = −0.5 V to +4.3 V) and supported by input/output voltage specifications (VIN up to 3.6 V, VOUT up to VCC + 0.5 V in active mode). The NC7WP00K8X leverages this to simplify mixed-voltage board architecture.
What is the typical propagation delay of NC7WP00K8X at 3.3 V?
The typical propagation delay (tPLH/tPHL) of the NC7WP00K8X is 2.1 ns at VCC = 3.3 V with RL = 1 MΩ and CL = 10 pF, as measured per Figures 3 and 4 of the official datasheet. This value represents average delay across both gates and accounts for process variation at TA = 25 °C. Delay remains stable across temperature (−40 °C to +85 °C) and load capacitance, with max delay specified at 7.0 ns under worst-case conditions - confirming suitability for high-speed digital glue logic in compact systems using the NC7WP00K8X.
