Product details
Overview
NC7NZ14L8X from onsemi is a triple Schmitt-trigger inverter IC in the TinyLogic UHS family, designed for noise-immune signal conditioning and level translation in low-voltage digital systems. It operates across 1.65 V to 5.5 V, delivers ±24 mA output drive at 3 V, and achieves 3.7 ns typical propagation delay into 50 pF at 5 V - enabling robust timing in space-constrained portable and interface applications.
For engineers reviewing the NC7NZ14L8X datasheet, pinout, applications, or equivalent options, key selection factors include its MicroPak-8 (UQFN8) 1.6×1.6 mm package, overvoltage-tolerant inputs (up to 5.5 V), hysteresis-enabled noise rejection, and compatibility with mixed-supply logic interfacing.
Technical Context
The NC7NZ14L8X implements three independent Schmitt-trigger inverters using advanced CMOS process technology, supporting rail-to-rail input tolerance and power-down high-impedance I/O states. Its hysteresis voltage ranges from 0.15 V (1.65 V VCC) to 1.70 V (5.5 V VCC), ensuring reliable switching in noisy environments.
It features proprietary EMI/noise reduction circuitry and supports dynamic operation up to 10 MHz (per AC test conditions), with input capacitance of 2.5 pF and power dissipation capacitance of 9 pF at 3.3 V - optimized for low-power, high-speed signal integrity in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 3.7 ns at 5 V into 50 pF - supports sub-100 MHz signal edge rates in timing-critical paths |
| Output Drive | ±24 mA at 3 V - drives multiple standard CMOS loads or small capacitive traces without buffering |
| Hysteresis Voltage | 0.70 V min at 5.5 V VCC - rejects >700 mV of input noise, improving immunity in industrial or automotive interfaces |
| Input Tolerance | Up to 5.5 V independent of VCC - allows safe 5 V signal injection into 1.65–3.3 V systems for level translation |
| Package | MicroPak-8 (UQFN8), 1.6×1.6 mm, 0.5 mm pitch - fits ultra-dense layouts; requires solder paste stencil and reflow profile control |
Pinout & Package
NC7NZ14L8X is housed in an 8-pin MicroPak (UQFN8, Case 523AY), 1.6 mm × 1.6 mm, 0.5 mm pitch, bottom-terminal package with wettable flanks. Pin 1 is located at the bottom-left corner when top marking "P6" is read left-to-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y | Output of first inverter - connects to downstream logic or pull-up/pull-down network |
| 2 | 3A | Input of third inverter - accepts overvoltage-tolerant signals up to 5.5 V |
| 3 | 2Y | Output of second inverter - provides hysteresis-filtered inversion for clock or enable signals |
| 4 | GND | Ground reference - must be connected to low-impedance system ground plane |
| 5 | 2A | Input of second inverter - shares same Schmitt threshold as other inputs (VP/VN defined per VCC) |
| 6 | 3Y | Output of third inverter - used for signal regeneration or noise-sensitive reset path |
| 7 | 1A | Input of first inverter - primary interface point for noisy sensor or switch inputs |
| 8 | VCC | Supply voltage - decoupling capacitor (0.1 µF ceramic) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs with programmable hysteresis | Hysteresis scales with VCC (0.15–1.70 V), enabling consistent noise margin across supply voltages |
| Overvoltage-tolerant inputs (5.5 V) | Eliminates need for external level-shifting resistors when interfacing 5 V sensors to 3.3 V or lower MCU I/O |
| Power-down high-impedance I/O | Inputs and outputs float to high-Z when VCC = 0 V - prevents back-driving during hot-swap or partial power-down |
| Ultra-low input leakage (±0.1 µA max) | Preserves battery life in always-on wake-up circuits and reduces loading on high-impedance sources |
| EMI/noise reduction circuitry | Reduces radiated emissions during fast edge transitions - aids compliance in Class B consumer designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G14DCUR | Same 3-inverter + Schmitt function; 1.65–5.5 V VCC; but uses US8 (3.1 mm wide) package - 4× larger footprint than NC7NZ14L8X MicroPak | Preferred where board space is less constrained and legacy US8 assembly infrastructure exists | Select when footprint compatibility with existing US8-based designs is required; not suitable for 1.6 mm × 1.6 mm area-limited layouts |
| 74LVC1G14GW,125 | Single-channel Schmitt inverter in SC-70; requires three devices to match NC7NZ14L8X functionality; higher total board area and BOM count | Used when design requires modularity or staggered placement of inverters across PCB | Choose only if channel isolation or routing flexibility outweighs cost, size, and assembly efficiency penalties |
Compared with SN74LVC3G14DCUR and 74LVC1G14GW,125, the NC7NZ14L8X delivers identical logic functionality in the smallest possible footprint (1.6×1.6 mm), with integrated triple-channel layout reducing trace coupling and inter-device skew - critical for synchronized signal conditioning in wearables and miniaturized ECUs.

FAQ
What is the package type and dimensions of the NC7NZ14L8X?
The NC7NZ14L8X uses the MicroPak-8 (UQFN8) package, designated Case 523AY, measuring 1.6 mm × 1.6 mm with 0.5 mm pitch. It has no leads - terminals are exposed copper pads on the bottom surface, requiring precise stencil design and reflow profiling for reliable solder joint formation. The top marking is "P6", with pin 1 identified at the bottom-left corner when reading left-to-right.
Does the NC7NZ14L8X support operation at 1.8 V supply voltage?
Yes, the NC7NZ14L8X is fully specified for operation at 1.8 V (within its 1.65 V to 5.5 V VCC range). At 1.8 V, it maintains Schmitt-trigger functionality with VP ≈ 1.25 V and VN ≈ 0.45 V (typical), hysteresis ≈ 0.80 V, and tPD ≈ 6.3 ns into 50 pF - making it suitable for modern ultra-low-power microcontroller I/O conditioning.
Can the NC7NZ14L8X safely interface a 5 V sensor output to a 3.3 V microcontroller input?
Yes - the NC7NZ14L8X inputs tolerate up to 5.5 V regardless of VCC level. When powered at 3.3 V, it accepts 5 V logic signals without damage or external components, and outputs clean 3.3 V-compatible logic levels. This eliminates level-shifter ICs or resistor dividers in mixed-voltage sensor interface designs.
Is the NC7NZ14L8X pin-compatible with the NC7NZ14K8X?
No - the NC7NZ14L8X (MicroPak-8) and NC7NZ14K8X (US8) share identical logic functionality and pin functions, but differ physically: MicroPak-8 has bottom terminals and 1.6×1.6 mm footprint, while US8 has gull-wing leads and 3.1 mm width. They are not mechanically interchangeable; PCB layout and assembly processes differ significantly.
What is the maximum operating temperature range for the NC7NZ14L8X?
The NC7NZ14L8X is rated for operation from −40 °C to +85 °C ambient temperature. This industrial-grade range supports deployment in harsh environments such as factory floors, automotive cabins, and outdoor medical equipment - provided thermal design limits junction temperature to ≤150 °C per absolute maximum ratings.
