Product details
Overview
NC7SZ332L6X from onsemi is a single 3-input OR gate in the TinyLogic UHS family, designed for ultra-high-speed logic interfacing in space-constrained digital systems. It operates across 1.65 V to 5.5 V supply, delivers 2.4 ns typical propagation delay at 5 V into 50 pF, supports ±24 mA output drive at 3 V, and features overvoltage-tolerant inputs up to 5.5 V - enabling robust 5 V-to-3 V level translation in mixed-voltage microcontroller I/O expansion.
For engineers reviewing the NC7SZ332L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (MicroPak 6-pin), functional truth table (Y = A + B + C), power-down high-impedance behavior, absolute maximum ratings, and AC/DC electrical specifications per onsemi Rev. 4 (August 2024).
Technical Context
The NC7SZ332L6X implements standard positive-logic 3-input OR functionality with fully buffered CMOS outputs. Its advanced UHS process enables sub-3 ns propagation delay while maintaining rail-to-rail output swing and input tolerance beyond VCC - critical for voltage-level bridging between legacy 5 V peripherals and modern low-voltage controllers.
All three inputs (A, B, C) and the output (Y) are fully specified across −40 °C to +85 °C and 1.65–5.5 V VCC. The device enters high-impedance state when VCC = 0 V, and inputs remain functional up to 5.5 V regardless of VCC - eliminating external clamping diodes in mixed-supply signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 3-input OR gate (Y = A + B + C); no internal pull-ups/pull-downs - unused inputs must be externally tied HIGH or LOW. |
| Propagation Delay | 2.4 ns typical at VCC = 5 V, CL = 50 pF - enables reliable operation in >200 MHz clock-domain boundary logic. |
| Supply Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Output Drive | ±24 mA at VCC = 3 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering. |
| Input Voltage Tolerance | Inputs tolerate up to 5.5 V independent of VCC - allows safe connection to 5 V buses while powered from 3.3 V or lower. |
| Power-Down Behavior | Inputs and output go high-impedance when VCC = 0 V - prevents back-powering and enables hot-swap or partial-power-down system modes. |
| Quiescent Current | Max 20 µA over full temperature range - ensures negligible static power impact in battery-backed or always-on subsystems. |
Pinout & Package
NC7SZ332L6X uses the MicroPak™ 6-pin leadless package (SIP6, 1.45 mm × 1.00 mm, 0.5 mm pitch), optimized for ultra-dense PCB layouts and automated assembly. It is Pb-free, halogen-free, and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A | Primary OR input; accepts 0–5.5 V logic levels regardless of VCC; must not float. |
| 2 | GND | Ground reference for all internal circuitry and output return path; requires low-inductance connection. |
| 3 | Input B | Secondary OR input; electrically identical to Pin 1; shares same overvoltage tolerance and DC specs. |
| 4 | Output Y | Inverting-capable only via external logic; true OR output swings rail-to-rail (VOL < 0.1 V at 4 mA, VOH > 2.9 V at 3 V). |
| 5 | VCC | Positive supply input; decoupling capacitor (0.1 µF ceramic) required within 2 mm for stable high-speed operation. |
| 6 | Input C | Third OR input; completes 3-input function; VIH/VIL thresholds scale with VCC (e.g., VIH = 0.7×VCC at VCC ≥ 2.3 V). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High Speed | 2.4 ns tPD typ at 5 V enables use in timing-critical paths such as address decoding, interrupt combining, and status aggregation. |
| Overvoltage-Tolerant Inputs | 5.5 V input rating independent of VCC eliminates need for external level-shifting components in mixed-voltage I/O domains. |
| Power-Down High-Z | Automatic tri-state behavior at VCC = 0 V supports hot-plug detection, partial power gating, and system sleep mode isolation. |
| Pb-Free MicroPak Package | 1.45 mm × 1.00 mm footprint reduces board area by >40% vs. SC-88; compatible with standard reflow profiles and AOI inspection. |
| Noisy Environment Robustness | Patented EMI/noise reduction circuitry lowers switching noise coupling - validated in automotive and industrial sensor interface applications. |
Applications
| Industrial PLC I/O Expansion | USB-C Port Status Aggregation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G332DBVR | Same 3-input OR function; SC-70-6 package (2.0 × 1.25 mm); 3.5 ns tPD at 3.3 V; max VCC = 5.5 V; input tolerance = VCC + 0.5 V. | Larger footprint; lacks 5.5 V input tolerance - requires external clamping for 5 V signal sources. | Preferred when SC-70 is already used in design and 5 V inputs are absent or buffered. |
| 74AUP1G332GW,125 | 3-input OR in XSON-6 (1.25 × 1.0 mm); 5.2 ns tPD at 3.3 V; VCC range 0.8–3.6 V; input tolerance = VCC + 0.3 V. | Lower speed and narrower supply range; not suitable for 5 V interface or >3.6 V operation. | Optimal for ultra-low-power, single-supply 1.8 V/2.5 V systems where speed <100 MHz suffices. |
Compared with SN74LVC1G332DBVR and 74AUP1G332GW,125, the NC7SZ332L6X uniquely combines 5.5 V input tolerance, 2.4 ns speed at 5 V, and the smallest available footprint (1.45 × 1.0 mm), making it the only choice for compact, mixed-voltage, high-speed OR logic in new designs.

FAQ
What is the maximum input voltage the NC7SZ332L6X can tolerate?
The NC7SZ332L6X inputs tolerate up to 5.5 V DC regardless of VCC value - a key feature enabling direct interface with 5 V signals while operating from 1.8 V or 3.3 V supplies. This eliminates external level-shifting components in mixed-voltage designs and is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and Features section of the onsemi datasheet Rev. 4.
Does the NC7SZ332L6X support power-down mode?
Yes, the NC7SZ332L6X enters a high-impedance state on both inputs and output when VCC = 0 V - a documented power-down feature that prevents back-powering and supports hot-swap or partial-system shutdown. This behavior is explicitly stated in the Description section and verified in the Pin Descriptions and Functional Table of the official onsemi datasheet.
What is the propagation delay of the NC7SZ332L6X at 3.3 V supply?
At VCC = 3.3 V and CL = 50 pF, the NC7SZ332L6X has a typical propagation delay (tPLH/tPHL) of 3.0 ns, with a maximum of 8.0 ns over −40 °C to +85 °C. This value is directly extracted from the AC Electrical Characteristics table (page 5) of the onsemi datasheet Rev. 4 and reflects real-world performance under standard loading conditions.
Is the NC7SZ332L6X pin-compatible with other TinyLogic OR gates?
No - the NC7SZ332L6X is not pin-compatible with other TinyLogic OR variants like NC7SZ32 (2-input) or NC7SZ333 (3-input NOR), as each uses distinct pin assignments. The NC7SZ332L6X pinout (A-GND-B-Y-VCC-C) is unique to its 3-input OR function and verified in Figure 4 (MicroPak top view) and Pin Descriptions of the onsemi datasheet.
What package type does the NC7SZ332L6X use, and is it RoHS compliant?
The NC7SZ332L6X uses the MicroPak™ 6-pin leadless package (SIP6, 1.45 mm × 1.00 mm), and it is fully RoHS compliant, Pb-free, and halogen-free/BFR-free as confirmed in the Features section and DEVICE ORDERING INFORMATION table (page 6) of the onsemi datasheet Rev. 4.
