Product details
Overview
NC7NZ17L8X-L22185 from onsemi is a triple Schmitt-trigger buffer IC in an 8-pin MicroPak (UQFN8) package, operating from 1.65 V to 5.5 V, delivering 3.6 ns typical propagation delay at 5 V into 50 pF, ±24 mA output drive at 3 V, and 1.0 V hysteresis at 5 V - used for noise-immune signal conditioning in low-voltage digital interfaces.
For engineers reviewing the NC7NZ17L8X-L22185 datasheet, pinout, applications, or equivalent options, key selection criteria include input overvoltage tolerance (5.5 V independent of VCC), power-down high-impedance I/O behavior, and micro-footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements three independent non-inverting buffers, each with Schmitt-trigger inputs enabling robust noise rejection in slow-rising or noisy signal environments. It uses advanced CMOS fabrication to achieve ultra-high speed while maintaining low static power dissipation across its full 1.65–5.5 V supply range.
All inputs tolerate up to 5.5 V regardless of VCC, supporting mixed-voltage translation (e.g., 5 V logic driving 3.3 V or 1.8 V systems). Inputs and outputs enter high-impedance state when VCC = 0 V, enabling safe power sequencing and hot-swap capability.
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) | 3.6 ns into 50 pF at 5 V - enables timing-critical signal buffering in high-speed digital control paths |
| Output Drive | ±24 mA at 3 V - sufficient to directly drive multiple CMOS loads or moderate capacitive traces without external buffers |
| Hysteresis (VH) | 1.0 V at 5 V VCC - rejects >1 V of input noise, stabilizing signals from mechanical switches or long cables |
| Input Tolerance | 5.5 V absolute max, independent of VCC - allows 5 V inputs to be safely interfaced to sub-3 V systems |
| I/O State at VCC = 0 V | High-impedance - prevents back-powering or contention during power-down or sequencing |
Pinout & Package
NC7NZ17L8X-L22185 is housed in an 8-pin UQFN (MicroPak) package, 1.6 mm × 1.6 mm, 0.5 mm pitch, bottom-exposed thermal pad, JEDEC MO-255 compliant (Case 523AY).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts Schmitt-triggered logic signal; tolerant to 5.5 V |
| 2 | 1Y (Output) | Non-inverting buffered output of Input 1 - drives downstream logic or trace capacitance |
| 3 | 2A (Input) | Second buffer input - electrically isolated from other channels; same Schmitt characteristics as Pin 1 |
| 4 | GND | Ground reference for all I/O and internal circuitry - must be connected to system ground plane |
| 5 | 3Y (Output) | Non-inverting buffered output of Input 3 - shares no internal coupling with Pins 1–2 or 3–6 |
| 6 | 2Y (Output) | Non-inverting buffered output of Input 2 - provides third independent channel |
| 7 | 3A (Input) | Third buffer input - identical electrical behavior to Pins 1 and 3; fully decoupled |
| 8 | VCC | Positive supply rail - powers all three buffers; regulates internal bias and output drive strength |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs per channel | 1.0 V hysteresis at 5 V enables reliable switching in presence of EMI, crosstalk, or slow edges |
| Overvoltage-tolerant inputs | 5.5 V absolute max rating independent of VCC eliminates need for level-shifting resistors in mixed-voltage designs |
| Power-down high-Z I/O | Inputs and outputs float to high-impedance when VCC = 0 V - prevents bus contention during power sequencing |
| Ultra-small MicroPak package | 1.6 mm × 1.6 mm footprint saves >60% board area vs. standard SOIC-8, ideal for wearables and compact modules |
| Pb-free, RoHS-compliant construction | Meets J-STD-020B reflow profile and environmental compliance requirements for industrial and consumer applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Single-channel only; 5-pin SOT-23; 3.5 ns tPD at 3.3 V; no 5.5 V input tolerance | Requires three devices and more board area; unsuitable for 5 V input translation | Use only if space permits discrete placement and 5 V inputs are absent |
| 74LVC1G17GW,125 | Single-channel; 5-pin TSSOP5; 3.2 ns tPD; 5.5 V tolerant inputs; no power-down high-Z | Lacks VCC = 0 V high-Z behavior - risks contention during power sequencing | Acceptable where power sequencing is controlled externally and triple integration is not required |
Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, NC7NZ17L8X-L22185 uniquely integrates three Schmitt buffers in one 1.6 mm² package with 5.5 V input tolerance *and* true power-down high-Z - eliminating layout complexity, reducing BOM count, and enabling safer mixed-voltage system design.

FAQ
What is the maximum input voltage rating for NC7NZ17L8X-L22185?
The NC7NZ17L8X-L22185 supports DC input voltages up to 5.5 V, independent of the VCC supply voltage. This overvoltage tolerance allows safe interfacing with 5 V signals even when VCC is as low as 1.65 V - a key feature confirmed in the Absolute Maximum Ratings table and reinforced in the Features section of the datasheet.
Does NC7NZ17L8X-L22185 support power-down mode?
Yes, NC7NZ17L8X-L22185 enters a true high-impedance state on both inputs and outputs when VCC = 0 V. This behavior is explicitly documented in the Description and DC Electrical Characteristics sections, enabling safe power sequencing and preventing back-driving or contention in multi-rail systems.
What is the typical propagation delay of NC7NZ17L8X-L22185 at 3.3 V?
At 3.3 V VCC with 50 pF load, the typical propagation delay (tPLH/tPHL) of NC7NZ17L8X-L22185 is 4.3 ns, as specified in the AC Electrical Characteristics table under "CL = 50 pF, RL = 500 Ω" conditions. This value is measured across all three channels and verified over temperature.
Is NC7NZ17L8X-L22185 pin-compatible with other TinyLogic UHS buffers?
No - NC7NZ17L8X-L22185 uses an 8-pin MicroPak (UQFN8) package with a unique pinout (1A/1Y/2A/GND/3Y/2Y/3A/VCC). It is not pin-compatible with US8-packaged variants like NC7NZ17K8X, nor with single-channel equivalents such as SN74LVC1G17. The pin assignment is fixed per Figure 4 in the datasheet.
What is the hysteresis voltage of NC7NZ17L8X-L22185 at 1.8 V supply?
At 1.8 V VCC, the hysteresis voltage (VH) of NC7NZ17L8X-L22185 is 0.51 V (typical), derived from the DC Electrical Characteristics table where VH = VP − VN. This value ensures reliable noise margin for low-voltage sensor or switch interfaces operating near battery cutoff.
