Product details
Overview
NC7SP38L6X from onsemi is a single 2-input NAND gate with open-drain output, designed for ultra-low-power logic interfacing in space-constrained applications. It operates from 0.9 V to 3.6 V, delivers 2.9 ns propagation delay at 3.3 V (typ), supports input/output over-voltage tolerance up to 3.6 V, and features IOFF partial power-down protection - used in I²C bus level translation and low-voltage sensor interface circuits.
For engineers reviewing the NC7SP38L6X datasheet, pinout, applications, or equivalent options, key selection criteria include its open-drain output architecture, 0.9 V minimum supply compatibility, SC-88A/MicroPak package options, IOFF-enabled power-gating capability, and ±2.6 mA drive strength at 3.3 V.
Technical Context
The NC7SP38L6X implements standard TTL-compatible NAND logic with active-low open-drain output, requiring an external pull-up resistor for high-level assertion. Its IOFF circuitry disables input and output leakage paths when VCC = 0 V, enabling live insertion and hot-swap operation in multi-rail systems.
Designed within onsemi's TinyLogic ULP-A family, it uses advanced CMOS process technology to achieve sub-1 V operation while maintaining rail-to-rail input tolerance and robust ESD immunity (2000 V HBM). The device exhibits no internal latchup (±100 mA per JESD78 Class II) and supports input transition rates up to 10 ns/V at 3.3 V.
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 domains without level shifters. |
| tPD (Typ) | 2.9 ns at 3.3 V - ensures fast signal routing in timing-critical control paths like reset synchronization or interrupt arbitration. |
| IOFF Leakage | <0.5 µA at VCC = 0 V - prevents back-powering of powered-down rails during partial system shutdown. |
| IOL Drive | 2.6 mA at 3.3 V - supports standard I²C bus pull-up configurations with up to 400 kbps data rate under typical load. |
| Input Tolerance | Up to 3.6 V regardless of VCC - allows mixed-voltage inputs (e.g., 3.3 V GPIO driving 1.8 V domain) without external clamping. |
| ESD Rating | 2000 V HBM - meets industrial-grade robustness requirements for board-level handling and end-equipment reliability. |
Pinout & Package
NC7SP38L6X 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. It uses solderable exposed die pad for enhanced thermal performance and compact PCB footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input A | First NAND input; accepts 0.9–3.6 V logic levels independent of VCC value. |
| 2 (B) | Input B | Second NAND input; fully over-voltage tolerant and compatible with IOFF isolation. |
| 3 (GND) | Ground | Reference return path for all internal logic and output current sinking. |
| 4 (Y) | Open-Drain Output | Active-low output requiring external pull-up; sinks up to 2.6 mA at 3.3 V. |
| 5 (N.C.) | No Connect | Internally unconnected terminal; must be left floating or tied to GND per layout guidelines. |
| 6 (VCC) | Supply | Primary power rail; powers internal logic and enables IOFF control when asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low-Voltage Operation | Functional down to 0.9 V VCC - enables integration into energy-harvesting and battery-powered sensor nodes. |
| IOFF Partial Power-Down | Blocks >99.9% of I/O leakage when VCC = 0 V - essential for modular hot-swap subsystems and battery-backed modules. |
| Over-Voltage Tolerant I/O | Inputs and outputs withstand 3.6 V regardless of VCC setting - eliminates need for external voltage translators in mixed-supply designs. |
| MicroPak Packaging | 1.45 mm × 1.0 mm footprint with thermal pad - reduces PCB area by ~50% vs. SC-88A while improving thermal resistance (154°C/W). |
Applications
| I²C Bus Level Translation | Low-Power Sensor Interface |
|---|---|
Use Scenario: Translating signals between 3.3 V microcontroller I²C master and 1.8 V sensor slave. IC Role / Device Role / Timing Role: Open-drain NAND gate configured as bidirectional level shifter with external pull-ups on both sides. Use Value: Eliminates dedicated level translator ICs; leverages inherent over-voltage tolerance and IOFF to prevent back-current during sleep mode. | Use Scenario: Enabling/disabling analog sensor power via microcontroller-controlled enable line with voltage-domain isolation. IC Role / Device Role / Timing Role: NAND gate used as active-low enable controller with VCC tied to sensor rail and inputs driven from MCU GPIO. Use Value: Ensures zero leakage into powered-down sensor rail via IOFF, preserving battery life in always-on monitoring systems. |
| Reset Signal Conditioning | Interrupt Line Arbitration |
Use Scenario: Combining multiple hardware reset sources (power-on, watchdog, manual) into a single system reset input. IC Role / Device Role / Timing Role: NAND gate implementing active-low wired-OR logic; all inputs pulled high, output drives reset pin. Use Value: Provides deterministic reset assertion timing (2.9 ns tPD typ) and rail-flexible compatibility across mixed-voltage SoC subsystems. | Use Scenario: Prioritizing interrupt requests from multiple peripherals before feeding to a shared MCU interrupt pin. IC Role / Device Role / Timing Role: NAND gate used in combinational logic to mask lower-priority interrupts when higher-priority ones are active. Use Value: Enables sub-10 ns interrupt response latency while supporting 0.9 V–3.6 V peripheral I/O without additional buffering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NC7SP00L6X | Inverter (single NOT gate) in identical MicroPak package; same VCC range, IOFF, and speed specs. | Lacks dual-input logic function; suitable only where inversion-not NAND logic-is required. | Select NC7SP00L6X when design requires signal inversion rather than two-input logic combination. |
| SN74LVC1G00DBVR | TI part in SOT-23-5; 1.65–5.5 V VCC range; no IOFF; 3.7 ns tPD at 3.3 V; higher drive (±32 mA). | Not over-voltage tolerant above VCC; cannot safely interface 3.6 V inputs when VCC = 1.8 V. | Choose SN74LVC1G00DBVR only in fixed 3.3 V systems where IOFF and sub-1 V operation are unnecessary. |
Compared with NC7SP00L6X and SN74LVC1G00DBVR, the NC7SP38L6X uniquely combines dual-input NAND logic, 0.9 V operation, IOFF, and 3.6 V over-voltage tolerance - making it irreplaceable in ultra-low-power, mixed-voltage, and hot-swap-sensitive designs.

FAQ
What is the minimum operating voltage for NC7SP38L6X?
The NC7SP38L6X supports a minimum supply voltage of 0.9 V, verified across the full −40°C to +85°C operating temperature range. This enables direct use with emerging ultra-low-power microcontrollers and energy-harvesting power supplies. The NC7SP38L6X maintains functional logic behavior and specified timing (e.g., tPD ≤ 9.0 ns at 1.1–1.3 V) even at this threshold voltage.
Does NC7SP38L6X support hot-swap or partial power-down operation?
Yes, the NC7SP38L6X includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. This feature prevents back-current flow into unpowered sections of a system, making the NC7SP38L6X suitable for hot-plug modules and systems with independently controlled power domains. Measured IOFF leakage is <0.5 µA at room temperature.
Can NC7SP38L6X interface a 3.3 V input with a 1.2 V supply rail?
Yes, the NC7SP38L6X inputs are over-voltage tolerant up to 3.6 V regardless of VCC level. When powered from 1.2 V, it reliably accepts 3.3 V logic inputs without damage or clamping diode conduction. This capability is confirmed in the DC Electrical Characteristics table and eliminates the need for external voltage translators in mixed-supply designs using the NC7SP38L6X.
What is the maximum output sink current for NC7SP38L6X at 3.3 V?
At VCC = 3.3 V, the NC7SP38L6X can sink up to 2.6 mA while maintaining VOL ≤ 0.31 V, as specified in the DC Electrical Characteristics table. This drive strength supports standard I²C bus operation with typical pull-up resistors (e.g., 2.2 kΩ to 3.3 V) and ensures reliable low-state voltage margins in noise-prone environments. The NC7SP38L6X sustains this performance across the full industrial temperature range.
Is NC7SP38L6X pin-compatible with NC7SP38P5X?
No, NC7SP38L6X (MicroPak, 6-pin) and NC7SP38P5X (SC-88A, 5-pin) have different pin counts and layouts. The MicroPak variant includes a dedicated N.C. pin (Pin 5) and relocated VCC (Pin 6), whereas the SC-88A places VCC on Pin 5 and omits Pin 6 entirely. Layout redesign is required when substituting between these packages; the NC7SP38L6X does not offer drop-in replacement for the NC7SP38P5X.
