Product details

Overview

NC7SV32FHX from onsemi is a single 2-input OR gate in the TinyLogic ULP-A family, designed for ultra-low-power logic interfacing in space-constrained systems. It operates from 0.9 V to 3.6 V supply, delivers 1.6 ns typical propagation delay at 3.3 V, supports 24 mA I_O drive, and features IOFF partial power-down protection - used in battery-powered sensor nodes and level-shifting I/O buffers.

For engineers reviewing the NC7SV32FHX datasheet, pinout, applications, or equivalent options, key selection criteria include its MicroPak2 (UDFN6) 1.0×1.0 mm package, overvoltage-tolerant inputs up to 3.6 V, rail-to-rail input/output compatibility across 0.9–3.6 V V_CC, and guaranteed operation from −40 °C to +85 °C.

Technical Context

The NC7SV32FHX implements standard positive-logic OR functionality (Y = A + B) with CMOS-compatible inputs and push-pull outputs. Its IOFF circuitry disables current flow between inputs and outputs when V_CC = 0 V, preventing back-driving in partial power-down states.

It supports mixed-voltage system interfacing via overvoltage-tolerant inputs (up to 3.6 V regardless of V_CC) and rail-specified output voltage levels (V_OH ≥ V_CC − 0.2 V, V_OL ≤ 0.2 V at 3.3 V). Propagation delay scales inversely with V_CC, ranging from 15.7 ns at 0.9 V to 1.6 ns at 3.6 V under RL = 2 kΩ / CL = 15 pF conditions.

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)	1.6 ns at V_CC = 3.3 V - supports high-speed signal routing in low-latency control paths.
I_O Drive	±24 mA at V_CC = 3.3 V - sufficient to drive multiple 10 kΩ pull-up loads or fan-out to 10+ LVTTL inputs.
Input Voltage Tolerance	Up to 3.6 V independent of V_CC - allows safe connection to higher-voltage buses during hot-swap or mixed-supply sequencing.
IOFF Leakage	<0.5 µA at V_CC = 0 V - prevents unintended current paths when host subsystems are powered down.
Operating Temp	−40 °C to +85 °C - qualified for industrial ambient environments including automotive body electronics and portable instrumentation.

Pinout & Package

NC7SV32FHX uses the MicroPak2 (UDFN6) package: 1.0 mm × 1.0 mm, 0.35 mm pitch, 6-terminal, no-lead surface-mount. Pin 1 marked by dot; exposed thermal pad (not electrically connected).

Pin/Terminal	Circuit Role	Design Meaning
1	A Input	First OR operand; overvoltage-tolerant up to 3.6 V regardless of V_CC.
2	B Input	Second OR operand; identical electrical characteristics to Pin 1.
3	GND	Ground reference for logic thresholds and internal biasing; must be low-impedance.
4	Y Output	Active-high OR result; push-pull structure supports sourcing/sinking up to ±24 mA.
5	V_CC	Positive supply; powers internal logic and output stage; IOFF active when = 0 V.
6	No Connect	Internally unconnected; no external tie required; may be left floating or grounded per layout best practice.

Key Features

Feature	Design Value
Ultra-low V_CC operation	Functional down to 0.9 V - enables integration into energy-harvesting and coin-cell-powered systems.
IOFF partial power-down	Blocks current flow between A/B/Y and GND/V_CC when V_CC = 0 V - preserves isolation in multi-rail sleep modes.
Overvoltage-tolerant inputs	Accepts 0–3.6 V signals irrespective of V_CC - eliminates need for external clamping diodes in mixed-voltage I/O.
Low dynamic power	CPD = 8.0 pF - minimizes switching power (P_D = CPD × V_CC² × f) in high-frequency enable/control paths.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input OR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NC7SZ32P5X	SC-88A (SOT-363) package; 1.45 mm × 1.0 mm footprint; no exposed thermal pad; same electrical specs.	Preferred where board reflow profile or legacy footprint compatibility favors SC-88A over UDFN6.	Select NC7SZ32P5X if existing PCB layout uses SC-88A pads or requires larger solder joint margin.
SN74LVC1G32DBVR	TSSOP-5 package; wider V_CC range (1.65–5.5 V); higher drive (32 mA); no IOFF feature.	Suitable for 5 V tolerant systems or where higher output current is required beyond 24 mA.	Choose SN74LVC1G32DBVR only if 5 V interface capability or >24 mA drive is mandatory; lacks IOFF for partial power-down.

Compared with NC7SV32FHX, NC7SZ32P5X offers identical logic and DC performance in a larger, leaded package, while SN74LVC1G32DBVR extends voltage range and drive strength but omits IOFF - making NC7SV32FHX optimal for ultra-compact, low-voltage, multi-rail-isolated designs.

FAQ

What is the package type and dimensions of the NC7SV32FHX?

The NC7SV32FHX uses the MicroPak2 (UDFN6) package: 1.0 mm × 1.0 mm body size, 0.35 mm pin pitch, six terminals, and an exposed thermal pad. Its compact footprint matches space-critical layouts in wearables and sensor modules. The NC7SV32FHX marking "G6" appears adjacent to Pin 1, which is identified by a dot on the top surface.

Does the NC7SV32FHX support partial power-down, and how does it work?

Yes, the NC7SV32FHX includes IOFF circuitry that disables input/output current paths when V_CC = 0 V. This prevents back-driving of powered sections from unpowered ones - critical in multi-rail systems like portable devices with independent sensor and processor domains. The NC7SV32FHX maintains leakage below 0.5 µA under this condition, ensuring system-level power integrity.

Can the NC7SV32FHX interface between 1.8 V and 3.3 V logic domains?

Yes, the NC7SV32FHX supports mixed-voltage interfacing: its inputs tolerate up to 3.6 V regardless of V_CC, and its outputs swing rail-to-rail. When powered from 1.8 V, the NC7SV32FHX reliably accepts 3.3 V inputs and drives 1.8 V–compatible loads - eliminating external level shifters in many I/O aggregation scenarios.

What is the maximum operating frequency supported by the NC7SV32FHX?

The NC7SV32FHX does not specify a maximum clock frequency, but its propagation delay (t_PD) determines usable toggle rate. With 1.6 ns typical delay at 3.3 V, the NC7SV32FHX supports clean signal routing up to ~300 MHz in non-critical timing paths. For precise clock distribution, consult setup/hold margins in the target system - the NC7SV32FHX is intended for control and enable logic, not high-speed clock gating.

Is the NC7SV32FHX RoHS compliant and halogen-free?

Yes, the NC7SV32FHX is Pb-free, halogen-free/BFR-free, and RoHS compliant per EU Directive 2011/65/EU. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and carries UL 94 V-0 flammability rating. These compliance attributes are verified and documented in the official NC7SV32/D datasheet revision 4 (August 2024), applicable to the NC7SV32FHX ordering variant.
