Product details
Overview
NC7WZ16FHX from ON Semiconductor is a dual non-inverting buffer in the TinyLogic® UHS family, designed for level translation and signal conditioning in space-constrained digital systems. It delivers 2.4ns typical propagation delay at 5V, ±24mA output drive at 3V, and operates across 1.65V–5.5V supply range - enabling interoperability between 1.8V, 2.5V, 3.3V, and 5V logic domains.
For engineers reviewing the NC7WZ16FHX datasheet, pinout, applications, or equivalent options, key selection factors include its MicroPak2™ 1×1mm package, 7V-tolerant inputs for 5V-to-3V translation, ultra-low power-down leakage (<10µA), and guaranteed operation from –40°C to +125°C in industrial environments.
Technical Context
The NC7WZ16FHX implements two independent CMOS buffer stages with high-impedance inputs/outputs when VCC = 0V, supporting hot-swap and power-gating use cases. Its proprietary noise/EMI reduction circuitry suppresses switching transients without external filtering.
Input voltage thresholds scale with VCC (VIH = 0.70VCC, VIL = 0.30VCC for VCC ≥ 2.3V), and outputs maintain rail-to-rail swing (VOH ≥ VCC – 0.1V, VOL ≤ 0.1V) under 24mA load - ensuring robust noise margins in mixed-voltage PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 2.4ns typical at 5V into 50pF - enables timing-critical signal buffering in high-speed control paths |
| Supply Range | 1.65V to 5.5V - supports single-supply operation across LVCMOS, TTL, and mixed-voltage interfaces |
| Output Drive | ±24mA at 3V - drives multiple loads or longer traces without external buffers |
| Input Tolerance | 7V absolute max - allows safe 5V input on 3.3V/1.8V systems without level shifters |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure |
| Power Dissipation | 120mW max (MicroPak2™) - enables dense placement in thermally constrained modules |
| Quiescent Current | 10µA max - minimizes standby power in battery-backed or always-on subsystems |
Pinout & Package
NC7WZ16FHX uses the 6-lead MicroPak2™ package (1.00 × 1.00 mm body, 0.35 mm pitch), optimized for ultra-dense PCB layouts. The package features exposed die pad for thermal enhancement and solderable side-wettable flanks for automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Buffer 1 input - accepts 7V-tolerant logic signals; must be tied HIGH/LOW if unused |
| 2 | GND | Ground reference - low-inductance return path critical for EMI performance |
| 3 | A2 | Buffer 2 input - independent of A1; supports asynchronous signal routing |
| 4 | Y2 | Buffer 2 output - full-rail CMOS output capable of sourcing/sinking 24mA |
| 5 | VCC | Supply voltage - decoupling capacitor (0.1µF) required within 2mm for stable operation |
| 6 | Y1 | Buffer 1 output - electrically isolated from Y2; supports dual-channel fanout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High Speed | 2.4ns tPD at 5V enables sub-400MHz clock domain bridging without added latency |
| Over-Voltage Tolerant Inputs | 7V-rated inputs eliminate need for external clamping diodes in 5V-to-3.3V translation |
| Power-Down High-Z I/O | Inputs and outputs enter high-impedance state at VCC = 0V - prevents back-driving during power sequencing |
| Proprietary EMI Reduction | Internally slew-rate controlled outputs reduce radiated emissions by >6dB vs. standard buffers |
| MicroPak2™ Footprint | 1×1mm body with 0.35mm pitch saves >60% board area vs. SC70 while maintaining solder joint reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DBVR | Slower tPD (3.7ns @ 3.3V), lower drive (±24mA only at VCC ≥ 4.5V), no 7V input tolerance | Not suitable for 5V-to-3.3V translation; requires external clamping for overvoltage protection | Select when cost is primary constraint and system operates strictly within 1.65–3.6V with no mixed-voltage interfacing |
| 74LVC2G07GW,125 | Open-drain outputs (no push-pull), no 7V input tolerance, higher ICC (20µA typical) | Requires external pull-ups; unsuitable for driving capacitive loads directly or for level translation | Select only for wired-OR logic or I²C bus buffering where open-drain behavior is required |
Compared with SN74LVC2G17DBVR and 74LVC2G07GW,125, the NC7WZ16FHX uniquely combines 7V input tolerance, 2.4ns speed, and true push-pull drive in a 1×1mm footprint - making it the only option for compact, mixed-voltage, high-speed digital interface consolidation.

FAQ
What is the maximum input voltage rating for NC7WZ16FHX?
The NC7WZ16FHX supports DC input voltages up to 7.0V, independent of VCC level. This over-voltage tolerance enables direct interfacing of 5V signals into 3.3V or 1.8V systems without external protection components. Absolute maximum ratings specify –0.5V to +7.0V for VIN, and operation outside this range may cause permanent damage to the NC7WZ16FHX.
Does NC7WZ16FHX support hot-swap or partial power-down operation?
Yes, the NC7WZ16FHX enters a high-impedance state on all inputs and outputs when VCC = 0V, preventing back-driving and latch-up during hot-swap or power sequencing events. This feature is explicitly confirmed in the datasheet's "Description" section and validated across –40°C to +125°C. Unused inputs must still be held HIGH or LOW to avoid floating states in the NC7WZ16FHX.
What is the thermal resistance (θJA) of the NC7WZ16FHX package?
The NC7WZ16FHX uses the MicroPak2™-6 package, which has a specified junction-to-ambient thermal resistance (θJA) of 560°C/W. This value assumes standard JEDEC test conditions (single-layer copper, 1-inch² pad). For sustained 120mW power dissipation, the resulting junction temperature rise would exceed safe limits without additional PCB copper or airflow - confirming the NC7WZ16FHX is intended for intermittent or low-duty-cycle operation.
Can NC7WZ16FHX replace NC7WZ16L6X in an existing design?
Yes, the NC7WZ16FHX is a direct functional replacement for NC7WZ16L6X, sharing identical electrical specifications, pinout, and logic function. Both use 6-lead MicroPak packages with top mark "C7", but NC7WZ16FHX uses the newer MicroPak2™ variant (1×1mm, 0.35mm pitch) versus MicroPak™ (1.00mm wide). Layout adaptation is required due to footprint differences, though land pattern recommendations are provided in the NC7WZ16FHX datasheet.
What is the minimum supply voltage for guaranteed operation of NC7WZ16FHX?
The NC7WZ16FHX is fully specified to operate down to 1.65V VCC, with VIH/VIL thresholds scaling proportionally (e.g., VIH = 0.75VCC at 1.65–1.95V). Below 1.65V, functionality is not guaranteed - the datasheet explicitly defines 1.65V as the minimum recommended operating voltage. Data retention remains valid down to 1.50V, but active logic operation requires ≥1.65V for the NC7WZ16FHX.
