onsemi NC7SV02FHX

Overview

NC7SV02FHX from onsemi is a single 2-input NOR gate logic IC in MicroPak2 (UDFN6) package, operating from 0.9 V to 3.6 V supply, with 1.5 ns typical propagation delay at 3.3 V, ±24 mA I_O drive capability, and input/output over-voltage tolerance up to 3.6 V - used in low-power voltage-level translation and signal conditioning in portable battery-powered systems.

For engineers reviewing the NC7SV02FHX datasheet, pinout, applications, or equivalent options, key selection considerations include its ultra-low power operation across sub-1V to 3.6V rails, IOFF-enabled partial power-down protection, SC-88A/MicroPak/MicroPak2 package compatibility, and guaranteed performance over −40°C to +85°C.

Technical Context

The NC7SV02FHX implements standard positive-logic NOR functionality (Y = NOT(A OR B)) using advanced CMOS process technology optimized for ultra-low-power (ULP-A) operation. It supports true bidirectional voltage translation between mixed-supply domains due to over-voltage tolerant inputs/outputs and rail-to-rail switching behavior.

Its IOFF feature disables current flow between powered and unpowered sections when V_CC = 0 V, preventing back-drive damage during hot-insertion or partial system power-down. Propagation delay scales predictably with V_CC, ranging from 14.4 ns at 0.9 V to 1.5 ns at 3.3 V under 500 Ω / 30 pF load conditions.

Key Specifications

Pinout & Package

NC7SV02FHX is packaged in MicroPak2 (UDFN6, 1.0 mm × 1.0 mm, 0.35 mm pitch), a leadless, bottom-terminal, space-constrained package requiring solder paste stencil optimization and X-ray inspection for assembly validation.

FAQ

What is the minimum supply voltage at which NC7SV02FHX guarantees functional operation?

The NC7SV02FHX guarantees full logic functionality and timing compliance down to 0.9 V V_CC, as specified in the Recommended Operating Conditions table. At this voltage, propagation delay increases to 14.4 ns (typical), but input thresholds and output drive remain valid per datasheet limits. Operation below 0.9 V is not characterized and may result in undefined behavior or increased static current.

Does NC7SV02FHX support hot-swapping between powered and unpowered system sections?

Yes - the NC7SV02FHX incorporates IOFF circuitry that actively disables current flow through inputs and outputs when V_CC = 0 V. This prevents back-driving of powered domains and protects against latch-up during hot-plug events. The maximum IOFF leakage is specified at 0.5 μA across −40°C to +85°C, ensuring reliable isolation in modular or field-replaceable subsystems.

Can NC7SV02FHX safely interface a 3.3 V microcontroller GPIO with a 5 V peripheral signal?

No - while NC7SV02FHX inputs tolerate up to 3.6 V regardless of V_CC, they are not rated for sustained 5 V input. Applying 5 V exceeds the absolute maximum VIN rating of −0.5 V to +4.3 V and risks permanent damage. For 5 V interface, use a dedicated level translator or add external clamping (e.g., Zener + series resistor), or select a device with 5 V-tolerant inputs like SN74LVC1G02.

What is the function of Pin 6 (N.C.) on NC7SV02FHX, and can it be grounded?

Pin 6 on NC7SV02FHX is explicitly designated "No Connect" (N.C.) in the datasheet and has no internal connection. It must remain electrically floating - grounding, pulling high, or connecting to any net violates the manufacturer's assembly guidance and may compromise thermal performance or ESD robustness. The MicroPak2 package uses this terminal solely for mechanical symmetry and thermal dissipation; no electrical role is assigned.

How does the power dissipation capacitance (CPD = 8.0 pF) of NC7SV02FHX impact dynamic power consumption?

The CPD value of 8.0 pF directly determines dynamic power draw via P_D = CPD × V_CC² × f. At 3.3 V and 10 MHz toggle rate, NC7SV02FHX consumes ~0.87 mW dynamically - significantly lower than standard LVC gates (CPD ≈ 20–30 pF). This enables efficient clock-gating and burst-mode operation in always-on sensor nodes without thermal derating concerns.
