Product details
Overview
NC7NP14L8X from ON Semiconductor is a triple Schmitt-trigger inverter IC in the TinyLogic® ULP family, designed for ultra-low-power signal conditioning in battery-constrained systems. It operates from 0.9V to 3.6V VCC, delivers ±2.6mA drive at 3.0V, and features 3.6V overvoltage-tolerant I/Os - enabling robust interfacing with mixed-voltage logic domains in portable medical sensors and IoT edge nodes.
For engineers reviewing the NC7NP14L8X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (MicroPak-8), confirmed Schmitt-trigger hysteresis (0.6V typ. at 3.0V), propagation delay (1.0–9.5ns across voltage range), power-off high-Z behavior, and validated alternatives for low-voltage logic inversion in space- and energy-sensitive designs.
Technical Context
The NC7NP14L8X implements three independent inverting buffers with Schmitt-trigger inputs to reject noise on slow-rising or noisy signals - critical in mechanical switch debouncing and analog sensor signal conditioning. Its internal architecture minimizes inverter stages to reduce both static current (0.9µA ICC) and dynamic switching power (CPD = 8.0pF).
It uses advanced CMOS fabrication optimized for sub-1V operation, supporting rail-to-rail input tolerance and output swing while maintaining hysteresis (VP/VN separation) across the full 0.9V–3.6V supply range - ensuring reliable logic thresholds even under brown-out conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9V to 3.6V - enables direct interface with Li-ion, coin-cell, and multi-rail embedded systems without level shifters. |
| I/O Voltage Tolerance | 3.6V - allows safe connection to higher-voltage peripherals (e.g., 3.3V GPIO) even when VCC = 0.9V. |
| Propagation Delay | 1.0ns (min) to 9.5ns (max) - supports >100MHz toggle rates at 3.0V with CL = 10pF, suitable for clockless control timing. |
| Hysteresis (VH) | 0.6V typical at VCC = 3.0V - rejects up to ±300mV of input noise, eliminating false triggering from EMI or contact bounce. |
| Quiescent Current (ICC) | 0.9µA - extends battery life in always-on wake-up circuits; consumes <1µW at 1.0V. |
| Output Drive | ±2.6mA at 3.0V - sufficient to drive 10pF loads or fan-out to ≥4 standard CMOS inputs without buffering. |
| Power-Off Behavior | High-impedance I/Os - prevents back-driving or leakage paths when VCC = 0V, essential for hot-swap and partial-power-down architectures. |
Pinout & Package
NC7NP14L8X is housed in an 8-lead MicroPak™ package (1.6mm wide), a leadless, bottom-terminated surface-mount package requiring solder paste stencil optimization and X-ray inspection for void control. Its compact footprint (1.6 × 1.6 mm) supports high-density PCB layouts in wearables and miniature modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5 | Inverter Input A1/A2/A3 | Schmitt-trigger inputs accepting 0–3.6V; internally biased to reject noise below hysteresis threshold. |
| 2, 4, 6 | Inverter Output Y1/Y2/Y3 | Push-pull CMOS outputs with rail-to-rail swing; support 2.6mA sink/source at 3.0V. |
| 7 | GND | Ground reference for all logic and power domains; must be low-inductance connection to minimize ground bounce. |
| 8 | VCC | Single-supply rail (0.9–3.6V); powers all three inverters and enables overvoltage-tolerant I/O operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | 0.9µA ICC ensures negligible drain in sleep-mode sensor nodes - extends 10-year coin-cell lifetime by >25%. |
| Schmitt-trigger input hysteresis | 0.6V typical at 3.0V VCC eliminates need for external RC debounce networks in pushbutton or reed-switch interfaces. |
| Overvoltage-tolerant I/O | 3.6V-rated inputs/outputs allow direct connection to 3.3V microcontrollers without level translators - reduces BOM count and layout area. |
| Quiet Series™ EMI reduction | Controlled slew rate and internal noise filtering lower radiated emissions - simplifies FCC/CE pre-compliance testing in handheld devices. |
| Power-off high-Z mode | Inputs and outputs enter high-impedance state at VCC = 0V - prevents unintended current flow during system reset or battery removal. |
Applications
| Medical Wearable Sensor Interface | IoT Edge Node Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | No Schmitt-trigger input; 1.65–5.5V VCC; higher ICC (10µA); no overvoltage tolerance. | Suitable only where input signals are already clean and supply ≥1.65V; requires external filtering for noisy sources. | Select when cost is primary and noise immunity is not required; avoid in battery-powered switch interfaces. |
| 74LVC1G14GW,125 | Single Schmitt-trigger inverter (not triple); same 1.65–5.5V range; identical hysteresis profile but requires 3x die area for same function. | Requires three separate packages for triple inversion - increases PCB area and assembly cost vs. single NC7NP14L8X. | Choose only if board layout mandates individual device placement or thermal isolation per channel. |
Compared with SN74LVC1G04DBVR and 74LVC1G14GW,125, the NC7NP14L8X uniquely combines triple-channel integration, sub-1V operation, 3.6V I/O tolerance, and Schmitt-trigger noise rejection in one MicroPak-8 package - delivering 42% smaller footprint and 89% lower quiescent power than the combined alternatives.

FAQ
What is the minimum operating voltage for NC7NP14L8X?
The NC7NP14L8X operates down to 0.9V VCC, with guaranteed functionality including Schmitt-trigger hysteresis, output drive (±20µA), and power-off high-Z behavior. At 0.9V, propagation delay is 66ns (CL = 10pF), and quiescent current remains ≤0.9µA - making it suitable for single-cell alkaline or lithium-thionyl-chloride battery systems where voltage drops below 1.0V during discharge.
Does NC7NP14L8X support hot insertion or partial power-down?
Yes. The NC7NP14L8X enters power-off high-impedance mode when VCC = 0V, isolating inputs and outputs from back-driving or leakage currents. This enables safe hot-plug operation in modular sensor systems and supports partial power-down of subsystems without affecting shared signal lines - a key requirement in field-upgradable IoT gateways.
Can NC7NP14L8X drive a 15pF capacitive load at 3.0V?
Yes. At VCC = 3.0V and CL = 15pF, the NC7NP14L8X achieves tPHL/tPLH ≤ 9.5ns (max) with ±2.6mA drive capability. Its Quiet Series™ design ensures controlled edge rates that prevent ringing or overshoot, maintaining signal integrity without external termination - verified in AC loading tests per Figure 1 and 2 of the datasheet.
Is NC7NP14L8X pin-compatible with other TinyLogic® inverters?
No. The NC7NP14L8X uses the 8-lead MicroPak™ package (MAC08A), which differs physically and electrically from US8 (MAB08A) and SC70 packages used by other TinyLogic® variants. While functional equivalents exist (e.g., NC7NP14K8X in US8), the MicroPak variant requires unique land pattern, solder paste volume, and reflow profile - no mechanical or electrical pin compatibility exists across package types.
What is the hysteresis voltage of NC7NP14L8X at 1.8V supply?
At VCC = 1.8V, the NC7NP14L8X exhibits a typical hysteresis voltage (VH) of 0.8V, with min/max values of 0.09V and 0.8V respectively. This provides robust noise margin against ±400mV interference - sufficient for reliable operation in motor-driven appliances or industrial enclosures where conducted EMI exceeds 200mV peak-to-peak.
