onsemi NC7SV14L6X

Overview

NC7SV14L6X from ON Semiconductor is a single-channel Schmitt-trigger inverter in the TinyLogic® ULP-A family, designed for ultra-low-power, high-speed signal conditioning in battery-powered and space-constrained systems. It operates across 0.9V–3.6V V_CC, delivers 1.5 ns typical propagation delay at 3.0V, supports ±24 mA output drive, and features power-off high-impedance I/Os - enabling use in level-shifting, noise-immune signal inversion, and wake-up detection circuits.

For engineers reviewing the NC7SV14L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (6-pin MicroPak), confirmed Schmitt-trigger hysteresis (0.40 V typ at 2.7V), absolute maximum ratings, real-world drive capability per supply voltage, and validated alternatives for low-voltage logic inversion with noise immunity.

Technical Context

The NC7SV14L6X implements a single inverting buffer with hysteresis on the input stage to reject noise on slow or noisy signals - critical in industrial sensor interfaces and push-button debouncing. Its CMOS-based ULP-A architecture enables sub-1µA quiescent current while maintaining rail-to-rail output swing and overvoltage-tolerant I/Os up to 3.6V regardless of V_CC.

It uses patented Quiet Series™ circuitry to suppress simultaneous switching noise and EMI, and its power-off high-Z behavior prevents back-driving during partial power-down - essential in multi-rail portable systems where V_CC may be sequenced or gated.

Key Specifications

Pinout & Package

FAQ

What is the minimum operating voltage for NC7SV14L6X?

The NC7SV14L6X operates down to 0.9V V_CC, with specified performance including 12.0 ns typical propagation delay and ±0.1 mA output drive. Below 0.9V, functionality is not guaranteed per datasheet limits, and parameters such as hysteresis voltage and output swing degrade outside rated conditions. Always validate timing margins in final design at actual V_CC min.

Does NC7SV14L6X support level shifting between different voltage domains?

Yes - NC7SV14L6X supports true level shifting: its inputs tolerate up to 3.6V regardless of V_CC (e.g., 1.2V supply), and its output swings rail-to-rail (V_OH ≥ V_CC−0.2V, V_OL ≤ 0.2V). This allows safe translation from 3.3V logic to 1.2V logic domains without external resistors or clamps, provided load capacitance remains ≤30 pF.

How does the Schmitt trigger in NC7SV14L6X improve noise immunity?

The NC7SV14L6X features programmable hysteresis (e.g., 0.40 V typ at 2.7V V_CC), meaning its input switches at different thresholds for rising (V_P) and falling (V_N) edges. This creates a noise margin that prevents multiple toggles on slow or noisy signals - critical for push-button inputs, comparator outputs, or long PCB traces where ringing or EMI could cause false triggers.

Can NC7SV14L6X be used with V_CC = 0V (powered down)?

Yes - NC7SV14L6X enters power-off high-impedance mode when V_CC = 0V: both input (A) and output (Y) terminals present <0.5 µA leakage and behave as open circuits. This prevents back-driving of upstream devices or bus contention in multi-supply systems during sleep or hot-swap sequences - a key advantage over standard inverters.

What is the recommended PCB layout for NC7SV14L6X in MicroPak™ package?

For NC7SV14L6X in MicroPak™, use a symmetric thermal pad (0.3 × 0.3 mm) with 4–6 thermal vias to inner ground plane, avoid solder mask over the pad, and route A/Y traces short and away from noisy clocks or switching regulators. Place a 100 nF X7R ceramic capacitor within 2 mm of V_CC–GND pins. Follow ON Semiconductor's AN-1001 MicroPak assembly guide for reflow profile and stencil design.
