Product details
Overview
NC7SP32L6X from onsemi is a single 2-input ultra-low-power OR gate in MicroPak™ package, designed for logic-level translation and signal combining in battery-powered and space-constrained systems operating from 0.9 V to 3.6 V supply. It delivers 2.7 ns typical propagation delay at 3.3 V, supports IOFF partial power-down protection, and features over-voltage tolerant inputs/outputs up to 3.6 V - enabling use in mixed-voltage I/O domains such as IoT sensor nodes and portable wearables.
For engineers reviewing the NC7SP32L6X datasheet, pinout, applications, or equivalent options, key selection criteria include its sub-1-V operation capability, 2.6 mA drive strength at 3.3 V, SC-88A/MicroPak package compatibility, IOFF-enabled system-level power gating, and guaranteed performance across −40°C to +85°C industrial temperature range.
Technical Context
The NC7SP32L6X implements a standard positive-logic OR function (Y = A + B) using advanced CMOS process technology optimized for ultra-low static and dynamic power. Its input structure supports voltage-level translation between 0.9 V and 3.6 V domains without external biasing, and the IOFF feature disables current flow when VCC = 0 V - preventing back-powering of powered-down rails.
Propagation delay scales predictably with supply voltage (e.g., 5.7 ns max at 3.0–3.6 V, 12.1 ns max at 1.65–1.95 V), and output drive capability is specified across full VCC and temperature ranges: VOH ≥ VCC − 0.1 V (IOH = −2.6 mA), VOL ≤ 0.31 V (IOL = 2.6 mA). Input leakage remains ≤ ±0.5 µA over operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC 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 families without level shifters. |
| tPD (Typ) | 2.7 ns at 3.3 V - supports high-speed control signaling in real-time sensor fusion and low-latency status reporting paths. |
| IOFF Support | Active when VCC = 0 V - prevents unwanted current flow between powered and unpowered subsystems during partial shutdown. |
| Input Tolerance | Up to 3.6 V regardless of VCC - allows safe connection to higher-voltage control signals without clamping diodes. |
| Drive Strength | ±2.6 mA at 3.3 V - sufficient to drive multiple CMOS inputs or short PCB traces in compact wearable PCB layouts. |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade deployment in automotive cabin modules and outdoor edge devices. |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets robustness requirements for manual handling and board-level assembly in contract manufacturing. |
Pinout & Package
NC7SP32L6X is packaged in MicroPak™ (Case 127EB), a 6-pin leadless package measuring 1.45 mm × 1.0 mm × 0.55 mm with bottom-side thermal pad and Q4 pin 1 orientation. The package is RoHS-compliant, halogen-free, and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input A | First OR operand input; accepts 0.9–3.6 V logic levels independent of VCC. |
| 2 (B) | Input B | Second OR operand input; electrically identical to Pin 1 with same voltage tolerance and leakage specs. |
| 3 (GND) | Ground Reference | Primary return path for supply and signal currents; must be connected to system ground plane for noise immunity. |
| 4 (Y) | Output Y | OR result (Y = A + B); actively driven high/low or high-impedance if unused (no internal pull-up/down). |
| 5 (N.C.) | No Connect | Internally unconnected; must remain floating - no external connection or routing allowed. |
| 6 (VCC) | Supply Voltage | Power rail input; bypass capacitor (0.1 µF ceramic) required within 2 mm for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low-Voltage Operation | Functional down to 0.9 V VCC - enables integration into energy-harvesting subsystems with weak or variable supply rails. |
| IOFF Partial Power-Down | Input/output isolation when VCC = 0 V - eliminates cross-rail leakage in multi-rail systems during sleep mode. |
| Over-Voltage Tolerant I/O | Inputs and outputs withstand 3.6 V regardless of VCC setting - simplifies interconnection with legacy 3.3 V peripherals. |
| Low Dynamic Power | CPD = 6.0 pF - minimizes switching power (PD = CPD × VCC² × f) in always-on sensor wake-up circuits. |
| MicroPak™ Footprint | 1.45 mm × 1.0 mm - reduces PCB area by >50% vs. SC-88A, critical for ultra-compact hearable and medical patch designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NC7SP32P5X | Same die, SC-88A (5-pin) package; no Pin 5 (N.C.), Pin 6 absent; 1.8 mm × 1.2 mm footprint. | Requires larger PCB area; lacks MicroPak's thermal pad; not suitable for <1.5 mm² layout constraints. | Select NC7SP32P5X only when SC-88A is already standardized in production and board rework is prohibitive. |
| SN74LVC1G32DBVR | TI part; 1.65–5.5 V VCC range; 3.7 ns tPD at 3.3 V; no IOFF; 5-pin SOT-23 package. | Cannot operate below 1.65 V; no power-down isolation; unsuitable for sub-1.2 V energy harvesting or deep-sleep systems. | Choose SN74LVC1G32DBVR only if 5 V tolerance is required and IOFF is unnecessary in the target architecture. |
Compared with NC7SP32P5X and SN74LVC1G32DBVR, the NC7SP32L6X uniquely combines 0.9 V operation, IOFF, over-voltage tolerance, and the smallest available footprint - making it the sole option for next-generation ultra-miniaturized, multi-rail, battery-constrained designs where every nanovolt and square micron matters.

FAQ
What is the minimum supply voltage for reliable operation of the NC7SP32L6X?
The NC7SP32L6X is fully specified to operate down to 0.9 V VCC across −40°C to +85°C. At this voltage, propagation delay increases (e.g., 51.8 ns typ at 0.9 V, CL = 10 pF), but logic functionality and input/output thresholds remain guaranteed per datasheet limits. System validation at 0.9 V is recommended for critical timing paths.
Does the NC7SP32L6X support true bidirectional signal translation?
No - the NC7SP32L6X is a unidirectional OR gate with defined inputs (A, B) and output (Y). It does not provide automatic direction sensing or data flow reversal. However, its over-voltage tolerant inputs allow it to accept 3.6 V signals while powered from 1.2 V, enabling one-way level shifting without external components.
Can Pin 5 (N.C.) on the NC7SP32L6X be grounded or left floating?
Pin 5 is internally unconnected and must remain floating - no external connection is permitted. Grounding or pulling it high may cause unpredictable behavior or increased leakage. The NC7SP32L6X datasheet explicitly states "N.C. = No Connect" and shows no internal bond wire to this terminal.
How does IOFF protection work in the NC7SP32L6X during system sleep mode?
When VCC = 0 V, the NC7SP32L6X automatically disables internal conduction paths between inputs (A, B) and output (Y), limiting leakage current to ≤0.5 µA per pin. This prevents back-powering of a powered-down VCC rail by active signals on other system rails - a critical requirement in multi-voltage domain architectures.
Is the NC7SP32L6X pin-compatible with the NC7SP32P5X?
No - the NC7SP32L6X (MicroPak, 6-pin) and NC7SP32P5X (SC-88A, 5-pin) have different pin counts, layouts, and terminal assignments. Pin 5 (N.C.) and Pin 6 (VCC) exist only on the L6X variant; the P5X uses a 5-pin configuration with VCC on Pin 5. PCB layout and footprint are not interchangeable.
