Product details
Overview
NC7WP32L8X from ON Semiconductor (formerly Fairchild) is a dual 2-input OR gate in the TinyLogic® ULP family, designed for ultra-low-power logic interfacing in battery-constrained systems. It operates across 0.9V–3.6V VCC, delivers 3.0 ns typical propagation delay at 3.3V, supports 3.6V-tolerant I/Os, and features power-off high-impedance inputs/outputs - enabling use in voltage-level translation and always-on subsystems.
For engineers reviewing the NC7WP32L8X datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (0.9V–3.6V), dynamic power efficiency (CPD = 6.0 pF), I/O overvoltage tolerance, static drive capability (±2.6 mA @ 3.0V), and MicroPak™ package compatibility with space-constrained PCB layouts.
Technical Context
The NC7WP32L8X implements two independent OR logic functions using advanced CMOS process technology optimized for minimal static and dynamic power. Its internal architecture minimizes inverter stages-including output buffer-to reduce both ICC quiescent current (0.9 µA max) and capacitive switching losses.
It supports mixed-voltage system interfacing via 3.6V-tolerant I/Os while powered from as low as 0.9V, and incorporates Quiet Series™ noise/EMI reduction circuitry to suppress switching transients-critical for sensitive analog or RF-adjacent digital domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9V to 3.6V - enables direct integration with Li-ion, coin-cell, and multi-rail embedded systems without level shifters |
| tPD (Typ) | 3.0 ns @ 3.3V - ensures timing-critical signal combining (e.g., interrupt arbitration) meets sub-10 ns budgets |
| I/O Voltage Tolerance | Up to 3.6V regardless of VCC - allows safe connection to higher-voltage peripherals when VCC = 1.2V or 1.8V |
| IOH/IOL | ±2.6 mA @ 3.0V - sufficient to drive standard CMOS loads (e.g., multiple 74LVC inputs) without external buffers |
| CPD | 6.0 pF - defines dynamic power consumption PDYN = CPD × VCC² × f, critical for battery life modeling at 10 MHz |
| ICC (Max) | 0.9 µA - guarantees nanoamp-level standby current for always-on wake-up logic in IoT endpoints |
| Operating Temp | −40°C to +85°C - qualified for industrial and automotive cabin ambient environments |
Pinout & Package
Pb-Free 8-Lead MicroPak™ package (1.6 mm wide, JEDEC MO-187 variant), ultra-thin profile (0.55 mm max height), land-grid array (LGA) bottom-termination design requiring solder paste stencil optimization and reflow profiling per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | A1/B1, A2/B2 Inputs | Dual independent OR gate inputs; each pair accepts 0.9V–3.6V logic levels with 3.6V tolerance |
| 3, 7 | Y1/Y2 Outputs | CMOS-compatible push-pull outputs; high-impedance when VCC = 0V (power-off isolation) |
| 4 | GND | Ground reference for all logic and power domains; must be low-inductance connection to minimize ground bounce |
| 8 | VCC | Single supply rail; powers both gates and enables I/O voltage translation functionality |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating voltage | Functional down to 0.9V VCC - supports energy harvesting and sub-1V MCU subsystems |
| Overvoltage-tolerant I/Os | Withstands 3.6V input/output signals at any valid VCC - eliminates need for external clamping diodes |
| Power-off high-Z I/O | Inputs and outputs enter high-impedance state when VCC = 0 - prevents back-driving powered-down sections |
| Quiet Series™ EMI control | Integrated slew-rate limiting and noise filtering - reduces radiated emissions in compact portable designs |
| MicroPak™ footprint | 1.6 mm × 1.6 mm body, 0.5 mm pitch - saves >70% board area vs. SOIC-8, ideal for wearables and sensor nodes |
Applications

Use Scenario: Monitoring fault signals from battery charger, USB PD controller, and thermal sensor in a portable device that must remain responsive during sleep. IC Role / Device Role / Timing Role: Always-on OR gate aggregating fault alerts to trigger immediate wake-up and safety shutdown routines. Use Value: Nanoamp ICC and power-off high-Z behavior ensure zero interference with host sleep states while maintaining real-time fault visibility. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G32DBVR | Higher minimum VCC (1.65V), faster tPD (3.5 ns @ 3.3V), but no sub-1V operation or 3.6V I/O tolerance | Best suited for 1.8V/3.3V-only systems where speed > voltage flexibility | Select when prioritizing propagation delay over ultra-low-voltage support |
| 74AUP2G32GM,125 | Similar 0.8V–3.6V range and 3.6V-tolerant I/Os, but larger XSON-8 (1.7 × 1.2 mm) and higher ICC (1.5 µA) | Compatible footprint and function, but less optimal for extreme area-constrained designs | Select when needing NXP's long-term supply assurance or existing qualification on AUP family |
Compared with SN74LVC2G32DBVR and 74AUP2G32GM,125, the NC7WP32L8X uniquely supports true 0.9V operation with nanoamp ICC and identical MicroPak™ footprint - making it the only choice for sub-1V energy-harvesting nodes requiring OR logic with zero layout impact.

FAQ
What is the minimum operating voltage for the NC7WP32L8X?
The NC7WP32L8X operates down to 0.9V VCC, with guaranteed functionality including propagation delay (24.0 ns typ), I/O logic thresholds, and output drive (±20 µA). This enables direct use with single-cell LiFePO₄ or energy-harvesting sources without regulation - a capability not shared by most competing dual OR gates.
Does the NC7WP32L8X support voltage-level translation between different logic families?
Yes - the NC7WP32L8X supports true voltage-level translation: its I/Os tolerate up to 3.6V regardless of VCC, allowing it to accept 3.3V or 2.5V inputs while powered from 1.2V or 1.8V. This eliminates external level shifters in mixed-supply systems, and is validated across the full −40°C to +85°C temperature range.
What is the significance of the "L8X" suffix in NC7WP32L8X?
The "L8X" suffix identifies the Pb-free 8-lead MicroPak™ package (package code MAC08A), distinct from the US8-packaged NC7WP32K8X. The MicroPak™ variant uses a 1.6 mm × 1.6 mm LGA footprint with bottom-terminal pads - requiring specific stencil aperture design and reflow profile, but offering superior board-area efficiency for miniaturized designs.
How does the NC7WP32L8X behave when VCC is disconnected or at 0V?
When VCC = 0V, the NC7WP32L8X enters power-off mode: all inputs and outputs transition to high-impedance states (IOFF ≤ 0.5 µA), preventing back-current flow or signal contention on powered-down buses. This behavior is specified and tested per JEDEC JESD78, ensuring safe hot-plug and partial-power-down operation.
Is the NC7WP32L8X pin-compatible with other TinyLogic ULP dual OR gates?
Yes - the NC7WP32L8X shares identical MicroPak™ pinout and function with NC7WP04L8X (inverter) and NC7WP08L8X (2-input AND), enabling drop-in substitution within the same package family. All use pins 1/2/5/6 as inputs, 3/7 as outputs, pin 4 as GND, and pin 8 as VCC, simplifying logic family migration on dense PCBs.
