Product details

Overview

NC7SV17FHX from ON Semiconductor is a single Schmitt-trigger buffer IC in the TinyLogic® ULP-A family, designed for low-voltage signal conditioning and noise-immune level translation in portable and battery-powered systems. It operates from 0.9V to 3.6V V_CC, delivers 1.5ns typical propagation delay at 3.0V, supports ±24mA output drive, features over-voltage tolerant I/Os up to 3.6V, and includes power-off high-impedance inputs/outputs.

For engineers reviewing the NC7SV17FHX datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, MicroPak2™-6 package mapping, Schmitt-trigger hysteresis values (e.g., 0.60V at 2.7V), DC/AC electrical specs across voltage grades, and validated alternative options for low-power logic interface design.

Technical Context

The NC7SV17FHX implements a single non-inverting buffer with Schmitt-trigger input thresholds (V_P = 1.50V, V_N = 0.60V at V_CC = 2.7V) enabling robust noise rejection on slow or noisy digital signals. Its CMOS architecture supports rail-to-rail input operation and 3.6V over-voltage tolerant I/Os independent of V_CC level (0.9V–3.6V).

It uses proprietary Quiet Series™ circuitry to suppress switching noise and EMI, and achieves ultra-low dynamic power via optimized gate sizing and low C_PD (10pF). The device enters high-impedance state when V_CC = 0V, preventing back-driving in partial-power-down systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	0.9V to 3.6V - Enables direct interface with Li-ion, coin-cell, and multi-rail embedded systems without level shifters.
t_PD (Typ.)	1.5ns at 2.7–3.6V - Supports >300MHz signal integrity in high-speed control paths with minimal latency.
I_OH/I_OL	±24mA at 3.0V - Drives multiple 74LVC loads or resistive terminations without external buffers.
V_IN Hysteresis	0.60V at 2.7V V_CC - Rejects up to 600mV of noise on input lines, critical for push-button, sensor, or open-drain interfaces.
I/O Voltage Tolerance	3.6V - Allows safe interfacing with 3.3V or 2.5V peripherals even when V_CC = 1.2V or 0.9V.
Power-Off Hi-Z	Yes - Prevents current leakage and bus contention during system sleep or hot-swap events.
C_PD	10pF - Limits dynamic power consumption to <1µW at 1MHz, extending battery life in always-on sensors.

Pinout & Package

NC7SV17FHX is packaged in a 6-lead MicroPak2™ (1.0mm × 1.0mm body, 0.35mm pitch) with wettable flank side walls for automated optical inspection. The package has no exposed pad and requires solder paste stencil optimization for 0201-scale placement.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No-connect - Must remain unconnected; not internally bonded or tested.
2	A	Schmitt-trigger input - Accepts 0–3.6V signals regardless of V_CC; enables clean edge detection on degraded waveforms.
3	GND	Digital ground reference - Requires local 0.1µF decoupling adjacent to pin for stable noise suppression.
4	Y	Buffered output - Delivers rail-aligned logic levels with full drive strength; compatible with 1.2V–3.3V load interfaces.
5	NC	No-connect - Electrically isolated; no internal connection or thermal path.
6	V_CC	Supply voltage input - Powers internal logic and output stage; must be filtered and stabilized per recommended layout.

Key Features

Feature	Design Value
Schmitt-trigger input	Provides 0.60V hysteresis at 2.7V V_CC, eliminating chatter on slow-rise signals from mechanical switches or analog comparators.
Over-voltage tolerant I/Os	Accepts 3.6V inputs/outputs while V_CC = 0.9V–3.6V - eliminates need for external clamping diodes in mixed-voltage domains.
Ultra-low dynamic power	10pF C_PD and sub-1µA I_CC enable microamp-level standby current in always-listening IoT nodes.
Quiet Series™ EMI reduction	Reduces simultaneous switching noise by >15dB vs. standard logic, easing EMC compliance in compact PCB layouts.
Power-off high-impedance	Input and output pins float to Hi-Z when V_CC = 0V - prevents back-powering or contention in modular/hot-plug subsystems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G17DBVR	Higher V_CC min (1.65V), no 0.9V operation; 3.3V I/O tolerance only; t_PD = 3.7ns typical at 3.3V.	Lacks ultra-low-voltage support and over-voltage tolerance - unsuitable for sub-1.2V battery systems.	Select when operating strictly in 1.65–5.5V range and cost sensitivity outweighs speed/power advantages.
74LVC1G17GW,125	Same 1.65–5.5V V_CC range; 5-pin SC-70 package; no 0.9V capability; t_PD = 3.5ns typical at 3.3V.	Requires external pull-ups for 1.2V logic compatibility; no power-off Hi-Z mode.	Prefer for legacy SC-70 footprint reuse where 0.9V operation and I/O over-voltage tolerance are not required.

Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, the NC7SV17FHX uniquely supports 0.9V operation, 3.6V I/O tolerance, and power-off Hi-Z - making it the only option for energy-harvesting and single-cell Li-ion designs requiring guaranteed noise immunity and zero-leakage shutdown behavior.

FAQ

What is the minimum V_CC required for NC7SV17FHX to operate correctly?

The NC7SV17FHX is fully specified down to 0.9V V_CC, with functional operation confirmed at that level including propagation delay (12.0ns typical), output drive (±0.1mA), and Schmitt thresholds. Below 0.9V, performance is not guaranteed and may result in undefined logic states or increased static current.

Does NC7SV17FHX support true 3.6V-tolerant I/Os when V_CC = 0.9V?

Yes, the NC7SV17FHX data sheet explicitly specifies 3.6V over-voltage tolerant I/Os across the full 0.9V–3.6V V_CC range. This means inputs and outputs can safely accept or drive 3.6V signals even when powered at 0.9V, eliminating external protection components in mixed-voltage interconnects.

What is the hysteresis voltage of NC7SV17FHX at 1.8V V_CC?

At 1.8V V_CC, the NC7SV17FHX exhibits a hysteresis voltage (V_H) of 0.09V (min) to 0.80V (max), with a typical value of 0.45V. This is derived directly from the V_P (positive threshold) and V_N (negative threshold) specifications in the DC Electrical Characteristics table.

Can NC7SV17FHX be used in hot-swap applications where V_CC may be absent?

Yes, the NC7SV17FHX features power-off high-impedance inputs and outputs. When V_CC = 0V, both A and Y pins enter Hi-Z state with leakage ≤0.5µA, preventing back-driving or bus contention - a key requirement for hot-plug modules and modular power architectures.

Is the MicroPak2™-6 package of NC7SV17FHX compatible with standard reflow profiles?

Yes, the NC7SV17FHX in MicroPak2™-6 (1.0mm × 1.0mm, 0.35mm pitch) is qualified for JEDEC J-STD-020D moisture sensitivity level 1 and supports standard lead-free reflow profiles up to 260°C peak. Its wettable flank design enables reliable automated optical inspection of solder joints.
