Product details

Overview

NC7SP17L6X from onsemi is a single-channel Schmitt-trigger buffer IC designed for ultra-low-power signal conditioning in space-constrained applications. It operates from 0.9 V to 3.6 V supply, delivers 2.6 ns typical propagation delay at 3.3 V, supports ±2.6 mA I_O drive, and features IOFF partial power-down protection. It is used in battery-powered sensor interfaces and level-shifting circuits where noise immunity and rail-to-rail input tolerance are critical.

For engineers reviewing the NC7SP17L6X datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (MicroPak, 6-pin UDFN), confirmed Schmitt-trigger hysteresis values across V_CC, validated IOFF behavior, real-world output drive capability at multiple supply voltages, and direct alternatives with documented functional alignment for low-voltage logic interfacing.

Technical Context

The NC7SP17L6X implements a single non-inverting buffer with hysteresis-based input thresholding-positive threshold (V_P) ranges from 0.34 V to 2.6 V and negative threshold (V_N) from 0.15 V to 0.6 V depending on V_CC, yielding hysteresis (V_H) from 0.08 V to 1.8 V. Its IOFF circuitry ensures high-impedance outputs when V_CC = 0 V, preventing back-drive current during partial power-down.

It uses CMOS process technology optimized for sub-1-V operation and integrates overvoltage-tolerant inputs rated up to 3.6 V independent of V_CC. The device exhibits no internal pull-ups or pull-downs, requires no external biasing, and maintains specified timing performance across −40 °C to +85 °C ambient temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	0.9 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters
t_PD (Typ)	2.6 ns at V_CC = 3.3 V, C_L = 10 pF - supports >300 MHz signal edge rates in clean digital paths
I_O Drive	±2.6 mA at V_CC = 3.3 V - sufficient to drive two 74LVC inputs or one 50 Ω transmission line under light load
Input Hysteresis	0.29 V (min) at V_CC = 0.9 V; up to 1.8 V (max) at V_CC = 3.0 V - rejects noise spikes ≤1.8 V peak-to-peak
IOFF Leakage	≤0.5 µA at V_CC = 0 V - prevents bus contention and power leakage in powered-down subsystems
Input Tolerance	−0.5 V to +4.3 V - allows safe connection to 3.6 V signals even when V_CC = 0.9 V
C_IN/C_OUT	2.0 pF / 4.0 pF - minimizes capacitive loading on source and load nodes in high-speed routing

Pinout & Package

NC7SP17L6X is packaged in MicroPak (UDFN6, 1.0 mm × 1.0 mm, 0.35 mm pitch), a leadless, bottom-terminal surface-mount package with exposed thermal pad. It is RoHS-compliant, halogen-free, and moisture sensitivity level (MSL) 1.

Pin/Terminal	Circuit Role	Design Meaning
1	No Connect (N.C.)	Internally unconnected; must be left floating or tied to GND per layout best practice
2	Input (A)	Schmitt-trigger input with hysteresis; accepts 0–3.6 V signals regardless of V_CC
3	GND	Ground reference for all internal circuitry and output return path
4	Output (Y)	CMOS-compatible buffered output; drives high/low states with rail-aligned VOH/VOL
5	No Connect (N.C.)	Internally unconnected; must be left floating or tied to GND
6	V_CC	Primary power supply pin; powers internal logic and output stage; decoupling capacitor required

Key Features

Feature	Design Value
Schmitt-trigger input with voltage-scalable hysteresis	Enables reliable switching in noisy environments (e.g., mechanical switch debouncing, analog sensor digitization) without external RC networks
IOFF partial power-down protection	Guarantees high-impedance outputs when V_CC = 0 V, eliminating back-current paths in multi-rail systems
Overvoltage-tolerant inputs (up to 3.6 V)	Permits interfacing with higher-voltage peripherals while operating from ultra-low V_CC, reducing need for discrete level translators
Ultra-small MicroPak (1.0 mm × 1.0 mm) footprint	Reduces PCB area by >50% vs. SC-88A; ideal for wearables, hearing aids, and compact IoT endpoints

FAQ

What is the minimum supply voltage for reliable operation of the NC7SP17L6X?

The NC7SP17L6X is fully specified down to 0.9 V V_CC, with guaranteed functionality including Schmitt-trigger thresholds, propagation delay, and output drive strength across −40 °C to +85 °C. Below 0.9 V, timing and logic behavior are not characterized, and the NC7SP17L6X may fail to meet datasheet specifications.

Does the NC7SP17L6X support true bidirectional signal flow?

No-the NC7SP17L6X is a unidirectional non-inverting buffer (A → Y only). It has no internal direction control, no bus-hold circuitry, and no capability to pass signals from Y to A. Its IOFF feature applies only to output isolation during V_CC power-down-not bidirectional data transfer.

Can the NC7SP17L6X be used with a 5 V input signal while powered from 1.8 V?

Yes-the NC7SP17L6X inputs are overvoltage tolerant up to 3.6 V, but not 5 V. Applying 5 V exceeds the absolute maximum rating of −0.5 V to +4.3 V and risks permanent damage. For 5 V signals, an external resistor divider or dedicated level translator is required before connecting to the NC7SP17L6X input.

Is the exposed thermal pad on the NC7SP17L6X package electrically connected?

No-the exposed pad on the NC7SP17L6X MicroPak package is not internally connected to any circuit node. It is recommended to solder it to a GND plane for thermal dissipation and mechanical stability, but it must not be tied to V_CC or left floating in high-reliability layouts.

How does the NC7SP17L6X behave when V_CC is ramped slowly during power-up?

The NC7SP17L6X includes built-in power-on reset behavior: output Y remains in a high-impedance state until V_CC exceeds ~0.7 V, then transitions to valid logic levels once V_CC reaches its operational range. This prevents glitch generation during brown-out conditions and ensures deterministic startup for the NC7SP17L6X in systems with uncontrolled power sequencing.
