Product details

Overview

NC7SV04FHX from onsemi is a single-channel ultra-low-power (ULP-A) inverter logic gate designed for level-shifting and signal conditioning in battery-powered and space-constrained systems. It operates across 0.9 V to 3.6 V supply voltage, delivers 1.5 ns typical propagation delay at 3.3 V, supports ±24 mA I_O drive strength, and features IOFF partial power-down protection. It is used in portable sensor interfaces and low-voltage microcontroller I/O buffering.

For engineers reviewing the NC7SV04FHX datasheet, pinout, applications, or equivalent options, key selection considerations include its MicroPak2 (UDFN6) 1.0×1.0 mm package, overvoltage-tolerant inputs up to 3.6 V, and guaranteed operation from −40 °C to +85 °C across the full V_CC range.

Technical Context

The NC7SV04FHX implements a single CMOS inverter with rail-to-rail input voltage tolerance and active-drive output stage. Its IOFF circuitry disables both PMOS and NMOS paths when V_CC = 0 V, preventing back-driving of powered rails - critical for hot-swap and multi-rail system isolation.

It uses standard TTL/CMOS-compatible input thresholds scaled to V_CC (VIH = 0.65×V_CC, VIL = 0.35×V_CC for V_CC ≥ 1.1 V), and maintains specified VOL ≤ 0.2 V and VOH ≥ V_CC − 0.2 V at 24 mA sink/source under 2.7–3.6 V operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	0.9 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters.
t_PD (Typ)	1.5 ns at V_CC = 3.3 V, R_L = 500 Ω, C_L = 30 pF - supports >300 MHz toggle rates in low-load applications.
I_O Drive	±24 mA at V_CC = 3.3 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (<15 pF) without external buffers.
Input Tolerance	Inputs tolerant to 3.6 V regardless of V_CC - allows safe interfacing with higher-voltage peripherals in mixed-supply systems.
IOFF Leakage	<0.5 µA at V_CC = 0 V - prevents current flow between unpowered and powered sections during partial power-down.
Operating Temp	−40 °C to +85 °C - qualified for industrial temperature operation without derating.
Package	MicroPak2 (UDFN6), 1.0 mm × 1.0 mm, 0.35 mm pitch - provides minimal PCB footprint and thermal resistance (θ_JA = 154 °C/W).

Pinout & Package

NC7SV04FHX is housed in a 6-pin MicroPak2 (UDFN6) package per Case 517DP, measuring 1.0 mm × 1.0 mm with 0.35 mm lead pitch. Pin 1 is marked by a dot and located at the top-left corner (Q4 orientation per tape-and-reel specification).

Pin/Terminal	Circuit Role	Design Meaning
1	No Connect (N.C.)	Internally unconnected; must be left floating or tied to GND for mechanical stability - no electrical function.
2	Input (A)	Inverting logic input; accepts DC voltages from 0 V to 3.6 V independent of V_CC.
3	GND	Ground reference for all internal circuitry and output driver return path.
4	Output (Y)	Inverted logic output; actively drives high or low with rail-to-rail swing and ±24 mA capability at 3.3 V.
5	V_CC	Positive supply pin; powers internal logic and output stage; must be decoupled locally with 100 nF ceramic capacitor.
6	No Connect (N.C.)	Internally unconnected; same handling as Pin 1 - no routing or connection required.

Key Features

Feature	Design Value
Ultra-low-power operation	ICC ≤ 0.9 µA max at V_CC = 3.6 V - extends battery life in always-on sensor nodes and wearables.
IOFF partial power-down	Blocks current flow between A/Y and GND/V_CC when V_CC = 0 V - enables safe hot-plug and domain isolation in multi-supply SoCs.
Voltage-level agnostic inputs	Accepts 0–3.6 V input signals regardless of V_CC setting - eliminates need for external level translators in mixed-V_CC designs.
High-speed low-V_CC performance	1.8 ns t_PD at V_CC = 1.8 V (RL = 500 Ω, CL = 30 pF) - maintains timing integrity in sub-2 V core logic domains.
Pb-free, RoHS-compliant packaging	MicroPak2 meets J-STD-020 MSL Level 1 - supports reflow assembly without moisture sensitivity concerns.

Equivalent & Alternatives

The following parts are listed as comparable options for similar inverter logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NC7SZ04FHX	Same MicroPak2 package but ULP (not ULP-A) variant; t_PD = 3.5 ns at 3.3 V (vs. 1.5 ns); lower drive (±16 mA).	Suitable where speed and drive strength are less critical; slightly lower ICC (0.5 µA vs. 0.9 µA).	Select NC7SZ04FHX only if timing budget allows ≥2× longer propagation delay and load current stays below 16 mA.
SN74LVC1G04DCKR	SC-70-5 package (larger, 2.0×2.1 mm); rated for 1.65–5.5 V; t_PD = 3.7 ns at 3.3 V; IOFF not supported.	Requires PCB redesign due to different footprint and pinout; lacks IOFF - unsuitable for partial power-down use cases.	Choose SN74LVC1G04DCKR only if 5.5 V tolerance or legacy SC-70 layout reuse is required and IOFF is unnecessary.

Compared with NC7SZ04FHX and SN74LVC1G04DCKR, the NC7SV04FHX uniquely combines 1.5 ns speed, 24 mA drive, IOFF, and 0.9 V operation in a 1.0×1.0 mm UDFN - making it the only option for high-density, ultra-low-voltage, hot-swap-capable inverter applications.

FAQ

What is the maximum operating voltage for NC7SV04FHX?

The NC7SV04FHX supports a maximum DC supply voltage (V_CC) of +3.6 V and withstands input/output voltages up to +4.3 V per Absolute Maximum Ratings. However, functional operation is guaranteed only within the Recommended Operating Conditions: V_CC = 0.9 V to 3.6 V and input voltage = 0 V to 3.6 V. Exceeding 3.6 V on V_CC risks permanent damage.

Does NC7SV04FHX support partial power-down (IOFF)?

Yes, NC7SV04FHX includes IOFF circuitry that disables both input and output paths when V_CC = 0 V. This prevents current backflow between powered and unpowered sections of a system. Measured IOFF leakage is ≤0.5 µA across −40 °C to +85 °C, confirming robust isolation for hot-swap and multi-rail applications.

What package type is used for NC7SV04FHX?

NC7SV04FHX uses the MicroPak2 (UDFN6) package per Case 517DP: a 6-pin, 1.0 mm × 1.0 mm, 0.35 mm pitch, bottom-terminated package with exposed thermal pad. It is distinct from SC-88A and standard MicroPak variants - confirmed by ordering code "FHX" and mechanical drawings in the datasheet.

Can NC7SV04FHX operate at 1.2 V supply?

Yes, NC7SV04FHX is fully specified down to V_CC = 0.9 V. At 1.2 V, it delivers t_PD ≤ 5.1 ns (typical), VIH ≈ 0.78 V, VIL ≈ 0.42 V, and VOL ≤ 0.2 V at 6 mA sink - enabling reliable integration with 1.2 V FPGA I/O banks and low-voltage ASIC cores.

Is NC7SV04FHX pin-compatible with NC7SV04P5X?

No, NC7SV04FHX (MicroPak2, 6-pin UDFN) is not pin-compatible with NC7SV04P5X (SC-88A, 5-pin SOT-353). They differ in pin count, pin assignment, and physical dimensions. NC7SV04FHX has two N.C. pins (1 and 6), while NC7SV04P5X uses a 5-pin configuration with V_CC on Pin 5 and no Pin 6 - requiring PCB layout change for substitution.
