Product details
Overview
NC7SV17P5X from ON Semiconductor is a single Schmitt-trigger buffer IC in the TinyLogic® ULP-A family, designed for signal conditioning and noise-immune level translation in ultra-low-power systems. It operates from 0.9V to 3.6V VCC, delivers 1.5ns typical propagation delay at 3.0–3.6V, supports ±24mA output drive, and features over-voltage tolerant I/Os up to 3.6V - ideal for battery-powered sensor interfaces and portable logic-level adaptation.
For engineers reviewing the NC7SV17P5X datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SC70-5 package mapping, Schmitt-trigger hysteresis values, power-off high-impedance behavior, and validated alternative options for low-voltage logic buffering where noise immunity and rail-to-rail compatibility are critical.
Technical Context
The NC7SV17P5X implements a single non-inverting buffer with Schmitt-trigger input thresholds (e.g., 0.70V/0.10V hysteresis at 1.65V VCC), enabling robust noise rejection on slow or noisy digital signals. Its CMOS process enables ultra-low ICC (0.9µA) and dynamic power dissipation (CPD = 10pF), while Quiet Series™ circuitry suppresses switching noise and EMI.
It supports true power-off protection: inputs and outputs enter high-impedance state when VCC = 0V, preventing back-driving of powered rails. The device is not a level shifter per se but achieves bidirectional voltage translation via 3.6V-tolerant I/Os across its full 0.9–3.6V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9V to 3.6V - enables direct interface with Li-ion, coin-cell, and multi-rail embedded systems without external regulators. |
| tPD (Typ.) | 1.5ns at 3.0–3.6V - supports >300MHz signal integrity in short-path timing-critical paths like clock fanout or reset synchronization. |
| IOH/IOL | ±24mA at 3.0V - drives multiple 74LVC inputs or small LED indicators without external buffers. |
| VIN/VOUT Tolerance | 3.6V over-voltage tolerant - allows safe interfacing with 3.3V or 2.5V peripherals even when NC7SV17P5X runs at 1.2V or 1.8V. |
| Hysteresis (ΔV) | 0.50V min at 1.65V VCC - rejects >500mV of common-mode noise on slow-switching analog-sensor or mechanical-switch inputs. |
| Power-Off State | High-Z I/Os at VCC = 0V - prevents current leakage or bus contention during partial power-down sequences. |
| IIN Leakage | ±0.5µA max - minimizes loading on high-impedance sources such as thermistor dividers or MEMS sensor outputs. |
Pinout & Package
NC7SV17P5X uses the 5-lead SC70 (EIAJ SC-88a) package, 1.25mm wide, with exposed pad not present. Pin 1 is marked by chamfered corner and extended mark length per JEDEC MO-252 UAAD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect - must be left unconnected; no internal connection or function. |
| 2 | A | Schmitt-trigger input - accepts 0.9–3.6V logic signals with hysteresis; immune to slow edges and noise. |
| 3 | GND | Ground reference - connects to system ground plane; required for proper threshold referencing and ESD path. |
| 4 | Y | Push-pull output - delivers rail-to-rail CMOS-compatible output with ±24mA drive capability at 3.0V. |
| 5 | VCC | Supply voltage - powers internal logic and output stage; supports 0.9–3.6V operation with ultra-low quiescent current. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable switching on slow or noisy signals (e.g., pushbuttons, analog comparators, sensor outputs) without external RC filtering. |
| Over-voltage tolerant I/Os | Accepts up to 3.6V inputs regardless of VCC level - eliminates need for discrete level-shifting components in mixed-supply systems. |
| Power-off high-impedance | Prevents back-current flow and bus contention when VCC is off - essential for hot-swap and partial-power-down architectures. |
| Quiet Series™ noise reduction | Reduces simultaneous switching noise (SSN) and radiated EMI - improves signal integrity in dense PCB layouts near RF or analog sections. |
| Ultra-low dynamic power | CPD = 10pF and ICC = 0.9µA enable >700-day battery life in 10MHz sensor polling applications (per Figure 1). |
Applications
| Industrial Sensor Interface | Portable Device Reset Conditioning |
|---|---|
Use Scenario: Interfacing slow-rising thermistor-based temperature sensors or mechanical limit switches to a 1.8V microcontroller GPIO. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans noisy, slow-edge signals before MCU sampling; provides rail-to-rail output compatible with 1.8V logic thresholds. Use Value: Eliminates external RC filters and reduces firmware debouncing overhead; extends battery life via sub-1µA quiescent current. | Use Scenario: Conditioning power-on reset (POR) or manual reset button signals in wearables and Bluetooth earbuds operating from 1.2V–3.3V supplies. IC Role / Device Role / Timing Role: Single-buffer isolates reset line from supply fluctuations; Schmitt input ensures clean, bounce-free assertion/deassertion. Use Value: Guarantees deterministic reset timing across voltage droops; 3.6V I/O tolerance allows reuse across multiple battery chemistries (LiPo, Li-ion, coin cell). |
| Low-Voltage Logic Level Translation | IoT Edge Node Signal Integrity |
Use Scenario: Bridging 1.2V FPGA I/O banks to 3.3V legacy peripherals (e.g., UART transceivers, EEPROMs) in space-constrained modules. IC Role / Device Role / Timing Role: Non-inverting buffer with over-voltage tolerant inputs acts as passive level translator without direction control or external biasing. Use Value: Reduces BOM count vs. dedicated translators; SC70-5 footprint (1.25mm × 2.0mm) fits tight routing channels near FPGA BGA escape zones. | Use Scenario: Driving clock or data lines between ultra-low-power MCUs and sub-GHz RF transceivers in LPWAN sensor nodes. IC Role / Device Role / Timing Role: High-speed buffer (1.5ns tPD) preserves edge integrity on 10–20MHz SPI or clock lines; Quiet Series™ minimizes RF-band interference. Use Value: Maintains timing margins under battery sag; low CPD and ICC extend operational lifetime beyond 10 years in sealed deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Higher VCC min (1.65V), no 0.9V operation; 3.6V I/O tolerance only up to VCC + 0.5V; tPD = 3.7ns typical at 3.3V. | Not suitable for sub-1.2V systems; requires tighter supply regulation; less noise margin on low-VCC inputs. | Select when operating strictly ≥1.65V and higher drive (32mA) is needed; avoid for coin-cell or energy-harvesting designs. |
| 74AUP1G17GW,125 | Wider VCC range (0.8–3.6V); lower ICC (0.5µA); tPD = 2.0ns at 3.0V; no over-voltage tolerance above VCC. | Lacks 3.6V I/O tolerance - cannot safely interface with 3.3V peripherals when running at 1.2V; requires external clamping for mixed-rail use. | Prefer for lowest static power in always-on monitoring; add external TVS if interfacing to higher-voltage domains. |
Compared with NC7SV17P5X, SN74LVC1G17DBVR offers higher drive but sacrifices sub-1.2V operation and true over-voltage safety, while 74AUP1G17GW,125 achieves lower quiescent current but removes critical 3.6V I/O tolerance - making NC7SV17P5X uniquely balanced for mixed-supply, battery-sensitive, noise-prone applications.

FAQ
What is the minimum supply voltage for reliable operation of the NC7SV17P5X?
The NC7SV17P5X is fully specified down to 0.9V VCC, with guaranteed performance including propagation delay, output drive, and Schmitt-trigger thresholds. At 0.9V, tPD is 12.0ns typical and IOH/IOL is ±0.1mA - sufficient for ultra-low-power wake-up and status signaling. Operation below 0.9V is not characterized and may result in undefined behavior or increased ICC.
Does the NC7SV17P5X support true bidirectional level shifting?
No, the NC7SV17P5X is a unidirectional buffer (A → Y) and does not support automatic bidirectional level shifting. However, its 3.6V over-voltage tolerant inputs allow it to accept higher-voltage signals (e.g., 3.3V) while operating from a lower VCC (e.g., 1.2V), functioning as a passive, single-direction level translator without external components - provided the driven load is compatible with the NC7SV17P5X's output voltage swing.
What is the purpose of the NC (No Connect) pin on the NC7SV17P5X SC70 package?
Pin 1 of the NC7SV17P5X is designated NC (No Connect) and has no internal connection. It must remain unconnected on the PCB - neither tied to GND, VCC, nor any signal. This pin serves solely as a mechanical alignment marker and pin-1 identifier per JEDEC MO-252 UAAD; connecting it risks unintended parasitic coupling or assembly defects.
How does the Schmitt-trigger input of the NC7SV17P5X improve noise immunity compared to a standard CMOS buffer?
The NC7SV17P5X Schmitt-trigger input provides hysteresis - e.g., 0.50V at 1.65V VCC - meaning the rising threshold (VP) and falling threshold (VN) differ significantly. This prevents multiple output transitions caused by slow edges or noise riding on the input signal, unlike standard CMOS buffers with near-zero hysteresis. For instance, a 300mV noise spike on a 1.8V signal will not trigger false toggling if VP − VN > 300mV.
Can the NC7SV17P5X be used in hot-swap or partial-power-down systems?
Yes, the NC7SV17P5X supports hot-swap operation: when VCC = 0V, both input (A) and output (Y) terminals enter a high-impedance state with <0.5µA leakage (IOFF), preventing back-current flow into powered subsystems. This behavior is explicitly characterized in the datasheet and makes NC7SV17P5X suitable for modular systems where boards may be inserted/removed while other rails remain active.
