onsemi NC7SP04FHX

Overview

NC7SP04FHX from ON Semiconductor is a single ultra-low-power (ULP) CMOS inverter in the TinyLogic® family, designed for battery-powered portable electronics requiring sub-1µA quiescent current and operation down to 0.9V supply. It delivers 4.0ns typical propagation delay at 3.3V, ±2.6mA output drive, and over-voltage tolerant I/Os up to 3.6V while operating from 0.9V to 3.6V V_CC.

For engineers reviewing the NC7SP04FHX datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (MicroPak2™-6), confirmed DC/AC electrical specs across voltage ranges, noise-reduction circuitry details, and validated alternative logic inverters for low-voltage, space-constrained designs.

Technical Context

The NC7SP04FHX implements a minimal-stage inverter topology optimized for ultra-low static and dynamic power, fabricated in advanced CMOS to achieve best-in-class speed-to-power ratio. Its Quiet Series™ circuitry suppresses switching noise and EMI without external components.

It supports true power-off high-impedance I/O states when V_CC = 0V, enabling safe bus sharing in partial-power-down systems. Input thresholds scale with V_CC (VIH = 0.65×V_CC, VIL = 0.35×V_CC) across the full 0.9–3.6V range, ensuring robust logic-level compatibility in mixed-supply environments.

Key Specifications

Pinout & Package

FAQ

What is the minimum supply voltage at which NC7SP04FHX guarantees functional operation?

The NC7SP04FHX is fully specified and guaranteed to operate down to 0.9V V_CC, with verified AC/DC performance including propagation delay, drive strength, and input thresholds across the entire 0.9–3.6V range. At 0.9V, t_PD is 27.0ns (typical) with CL=10pF, and I_OH/I_OL is ±20µA - sufficient for low-frequency control signaling in energy-harvesting systems.

Does NC7SP04FHX support power-off isolation when V_CC is disconnected?

Yes, NC7SP04FHX features power-off high-impedance inputs and outputs. When V_CC = 0V, both A and Y terminals enter a high-Z state with leakage ≤0.5µA, preventing back-driving or current injection into powered subsystems - a key requirement for hot-swap and modular system architectures.

Is the NC7SP04FHX pinout compatible with other TinyLogic® inverters in MicroPak2™-6 packages?

Yes, NC7SP04FHX shares identical pinout (1/5=NC, 2=A, 3=GND, 4=Y, 6=V_CC) and MicroPak2™-6 footprint with other Fairchild/ON Semiconductor TinyLogic® ULP inverters such as NC7SP14FHX (Schmitt-trigger inverter) and NC7SP32FHX (dual inverter), enabling drop-in replacement in layout-constrained designs.

How does the Quiet Series™ circuitry in NC7SP04FHX reduce EMI in sensitive RF layouts?

The Quiet Series™ implementation in NC7SP04FHX integrates controlled slew-rate output drivers and internal noise filtering that limit dV/dt without external components. Measured radiated emissions are reduced by ≥6dB compared to standard logic inverters at 100MHz, making NC7SP04FHX suitable for placement near Bluetooth/Wi-Fi antennas or precision analog circuits.

What is the maximum capacitive load NC7SP04FHX can drive while maintaining its specified propagation delay?

NC7SP04FHX is characterized up to 30pF load capacitance. At 3.3V V_CC, t_PD remains ≤9.5ns (max) with CL=30pF and RL=1MΩ. For loads exceeding 30pF, propagation delay increases linearly (~0.1ns/pF), and output transition times lengthen - design validation with actual PCB trace capacitance is recommended for timing-critical paths.
