onsemi NC7SV05L6X

Overview

NC7SV05L6X from ON Semiconductor is a single-channel ultra-low-power inverter with open-drain output, designed for level-shifting and wired-OR logic in space-constrained portable systems. It operates across 0.9V to 3.6V V_CC, delivers 24mA sink current at 3.0V, achieves 1.0ns typical propagation delay (2.7–3.6V), and features power-off high-impedance I/Os for system-level power gating.

For engineers reviewing the NC7SV05L6X datasheet, pinout, applications, or equivalent options, this device is selected for battery-powered IoT sensors, low-voltage interface translation, and always-on wake-up signal conditioning where sub-1ns timing and <1µA quiescent current are critical.

Technical Context

The NC7SV05L6X implements a CMOS-based inverter core with open-drain output architecture, enabling flexible pull-up configuration and voltage-level independence between input and output domains. Its Quiet Series™ EMI reduction circuitry suppresses switching noise without external filtering components.

It supports over-voltage tolerant I/Os up to 3.6V regardless of V_CC (0.9–3.6V), allowing safe interfacing with higher-voltage peripherals. Input leakage remains ≤±0.5µA across full temperature range (−40°C to +85°C), ensuring reliable operation in low-power sleep states.

FAQ

What is the minimum supply voltage for reliable operation of the NC7SV05L6X?

The NC7SV05L6X is fully specified down to 0.9V V_CC, with guaranteed functionality including 13.0ns typical propagation delay and ±0.1mA output drive. Below 0.9V, timing and drive performance degrade outside datasheet limits, so 0.9V is the validated lower bound for design use of the NC7SV05L6X.

Does the NC7SV05L6X require external pull-up resistors on its output?

Yes - the NC7SV05L6X features an open-drain output (pin 4, Y), which can only sink current. An external pull-up resistor to a defined voltage rail (e.g., 1.8V or 3.3V) is mandatory to establish HIGH logic levels. The value depends on rise time and bus capacitance but typically ranges from 1kΩ to 10kΩ for most portable applications using the NC7SV05L6X.

Can the NC7SV05L6X safely interface with 5V logic signals?

No - while the NC7SV05L6X has 4.6V absolute maximum I/O ratings, its over-voltage tolerance is limited to 3.6V under normal operation per the Recommended Operating Conditions table. Applying 5V signals risks permanent damage and violates the 3.6V V_IN/V_OUT max specification. For 5V interfacing, a dedicated level translator or clamping circuit is required alongside the NC7SV05L6X.

How does the NC7SV05L6X behave when V_CC is disconnected or at 0V?

When V_CC = 0V, both input (A) and output (Y) pins of the NC7SV05L6X enter high-impedance state per the Power-Off High-Impedance feature. This prevents back-driving or leakage through the device, protecting upstream and downstream circuitry - a key reliability feature for hot-swap or multi-rail power sequencing designs using the NC7SV05L6X.

What is the thermal resistance (θ_JA) of the NC7SV05L6X in its MicroPak™ package?

The NC7SV05L6X in the 6-lead MicroPak™ package has a junction-to-ambient thermal resistance (θ_JA) of 500°C/W, as specified in the Recommended Operating Conditions table. This value assumes standard JEDEC 2-layer test board conditions and informs thermal derating calculations for continuous operation at elevated ambient temperatures with the NC7SV05L6X.
