Product details
Overview
NC7NZ14L8X-L22185 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 VCC, 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 battery-powered IoT sensors and interface buffers.
For engineers reviewing the NC7NZ14L8X-L22185 datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.6×1.6 mm MicroPak-8 (UQFN8) package, overvoltage-tolerant inputs up to 5.5 V, hysteresis-based noise rejection, and power-down high-impedance I/O behavior.
Technical Context
This device implements three independent Schmitt-trigger inverters using advanced CMOS process technology, supporting rail-to-rail input operation and mixed-voltage interfacing without external level shifters. Its hysteresis voltage ranges from 0.15 V (1.65 V VCC) to 1.70 V (5.5 V VCC), with positive/negative thresholds tightly specified across temperature and supply.
The NC7NZ14L8X-L22185 features true power-down isolation: both inputs and outputs enter high-impedance state when VCC = 0 V, and input leakage remains ≤±0.1 µA over full VCC range. Propagation delay variation is controlled to ±0.5 ns between channels, ensuring matched timing for synchronized signal inversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 3.7 ns into 50 pF at 5 V - enables sub-100 MHz clock/data buffering with minimal skew |
| IOH/IOL | ±24 mA at 3 V - drives standard 50 Ω transmission lines or multiple 74LVC inputs directly |
| VIN Tolerance | Up to 5.5 V independent of VCC - allows safe 5 V signal injection into 1.65–3.3 V systems |
| Hysteresis (VH) | 0.70 V min at 5.5 V VCC - rejects >700 mV of common-mode noise on slow or noisy inputs |
| Power-Down State | High-Z I/O at VCC = 0 V - prevents back-powering and bus contention during system sleep |
Pinout & Package
NC7NZ14L8X-L22185 is housed in an 8-pin MicroPak (UQFN8) package, 1.6 mm × 1.6 mm, 0.5 mm pitch, with wettable flank leads for automated optical inspection. Pin 1 is located at the bottom-left corner when top mark "P6" is read left-to-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y | Inverter 1 output - drives downstream logic or analog threshold detectors with 24 mA sink/source capability |
| 2 | 3Y | Inverter 3 output - independently buffered; shares no internal nodes with other outputs |
| 3 | 2Y | Inverter 2 output - provides matched delay and hysteresis to channel 1 and 3 |
| 4 | GND | Digital ground reference - must be connected to lowest-impedance system ground plane |
| 5 | 2A | Inverter 2 input - Schmitt-trigger input accepts slow-rising signals (e.g., mechanical switch debouncing) |
| 6 | 3A | Inverter 3 input - tolerant to 5.5 V regardless of VCC; enables direct connection to legacy 5 V buses |
| 7 | 1A | Inverter 1 input - identical electrical characteristics to pins 5 and 6; fully interchangeable |
| 8 | VCC | Supply voltage - bypass capacitor (100 nF X7R) required within 2 mm of this pin for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.70 V minimum hysteresis at 5.5 V VCC, eliminating false triggering from EMI or slow edges |
| Overvoltage-tolerant inputs | Accepts 5.5 V signals while VCC is as low as 1.65 V - eliminates need for external level translators |
| Ultra-high speed | 3.7 ns tPD at 5 V enables use in 100+ MHz data paths and clock distribution networks |
| MicroPak-8 packaging | 1.6 mm × 1.6 mm footprint saves >60% board area versus US8, with improved thermal resistance (232°C/W) |
| Power-down isolation | Inputs/outputs go high-Z when VCC = 0 V - prevents current leakage and bus conflicts in multi-rail power sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G14DCUR | 3.3 V only VCC range (1.65–5.5 V not supported); 5.5 ns tPD at 3.3 V; same MicroPak-8 package | Lacks overvoltage tolerance - requires external clamping for 5 V inputs | Prefer when system uses fixed 3.3 V supply and no mixed-voltage interfacing is needed |
| 74LVC1G14GW,125 | Single-channel only; 3.3 V optimized; 4.2 ns tPD at 3.3 V; SOT353 (5-pin) package | Requires three devices for equivalent functionality; larger total footprint than single NC7NZ14L8X-L22185 | Select when board layout constraints favor discrete placement or channel independence is critical |
Compared with SN74LVC3G14DCUR and 74LVC1G14GW,125, the NC7NZ14L8X-L22185 uniquely combines triple-channel integration, 1.65–5.5 V universal supply support, and 5.5 V input tolerance in a 1.6 mm² package - reducing BOM count and PCB area while enabling mixed-voltage designs without redesign.

FAQ
What is the maximum input voltage rating for NC7NZ14L8X-L22185?
The NC7NZ14L8X-L22185 supports DC input voltages up to 6.5 V absolute maximum, with functional overvoltage tolerance to 5.5 V independent of VCC. This allows safe interfacing with 5 V signals even when powered from 1.65 V or 1.8 V rails - a key feature confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official datasheet.
Does NC7NZ14L8X-L22185 support power-down mode?
Yes, the NC7NZ14L8X-L22185 enters a true power-down state when VCC = 0 V: both inputs and outputs become high-impedance, with input/output leakage limited to ≤10 µA. This behavior is explicitly documented in the datasheet's Features section and DC Electrical Characteristics table under IOFF parameter, preventing back-powering and bus contention during system sleep cycles.
What is the typical propagation delay of NC7NZ14L8X-L22185 at 3.3 V?
At 3.3 V VCC with 15 pF load, the NC7NZ14L8X-L22185 exhibits a typical propagation delay (tPLH/tPHL) of 6.3 ns, per the AC Electrical Characteristics table. With 50 pF load, typical delay increases to 7.2 ns - values verified across −40 °C to +85 °C operating temperature range and consistent across all three inverter channels.
Is NC7NZ14L8X-L22185 pin-compatible with NC7NZ14K8X?
No, NC7NZ14L8X-L22185 is not pin-compatible with NC7NZ14K8X. The former uses an 8-pin MicroPak (UQFN8) package with pinout defined in Figure 4 of the datasheet, while the latter uses an 8-lead US8 package with different pin mapping (Figure 2). Although both contain identical logic functionality, their physical layouts and solder pad patterns differ - requiring separate PCB footprints.
What hysteresis voltage does NC7NZ14L8X-L22185 provide at 1.8 V supply?
At 1.8 V VCC, the NC7NZ14L8X-L22185 delivers a hysteresis voltage (VH) of 0.25 V minimum and 1.00 V maximum, as specified in the DC Electrical Characteristics table. This 0.25–1.00 V window ensures reliable noise rejection on slow-rising signals such as those from thermistors or potentiometers in low-power sensor front-ends.
