Product details
Overview
NL17SZ17XV5T2G-L22087 from onsemi is a single non-inverting Schmitt trigger buffer in SOT-553 package, operating from 1.65 V to 5.5 V supply, delivering 3.7 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and input overvoltage tolerance up to 5.5 V - used for noise-immune signal conditioning in low-power sensor interfaces and industrial I/O modules.
For engineers reviewing the NL17SZ17XV5T2G-L22087 datasheet, pinout, applications, or equivalent options, key selection criteria include Schmitt-trigger hysteresis (0.7 V min at 5.5 V), IOFF partial power-down support, 2.5 pF input capacitance, and SOT-553 footprint compatibility with space-constrained PCB layouts.
Technical Context
The NL17SZ17XV5T2G-L22087 implements a single-channel CMOS Schmitt-trigger input stage followed by a push-pull output driver with rail-to-rail swing. Its hysteresis (VH = 0.7 V typ at VCC = 5.5 V) enables reliable switching in noisy environments, while IOFF functionality isolates inputs when VCC = 0 V.
It supports mixed-voltage interfacing: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), and outputs drive loads up to 24 mA at 3.0 V with VOL ≤ 0.42 V and VOH ≥ 2.3 V - enabling direct connection to legacy 5 V logic or modern 1.8/3.3 V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports wide-input voltage operation across battery-powered and industrial supply rails. |
| tPD (typ) | 3.7 ns at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - enables high-speed signal buffering without timing bottlenecks. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small relays, or multiple CMOS inputs. |
| Input Hysteresis | 0.7 V (min) at VCC = 5.5 V - rejects >700 mV of noise on input signals, critical for switch debouncing and analog sensor digitization. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents back-driving during power sequencing or hot-swap events. |
| CIN / COUT | 2.5 pF each - minimizes capacitive loading on source circuits and preserves signal edge integrity. |
| ESD Rating | HBM: 2000 V - meets industrial-grade ESD robustness requirements without external protection. |
Pinout & Package
SOT-553 (Case 463B), 5-pin ultra-small surface-mount package measuring 1.60 mm × 1.20 mm × 0.55 mm with 0.50 mm pitch - optimized for high-density PCBs in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Positive supply input - must be decoupled locally with 0.1 µF ceramic capacitor to suppress switching noise. |
| 2 | NC | No-connect terminal - left unconnected per design; not internally bonded or electrically active. |
| 3 | A | Schmitt-trigger input - accepts 0–5.5 V logic levels independent of VCC; hysteresis improves noise margin. |
| 4 | Y | Non-inverting buffered output - delivers rail-to-rail CMOS-compatible signal with 24 mA sink/source capability. |
| 5 | GND | Ground reference - requires low-impedance return path to minimize ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | VT+ = 3.3 V / VT− = 1.2 V at VCC = 5.5 V - provides 2.1 V hysteresis window for reliable edge detection in noisy environments. |
| IOFF partial power-down | Input/output isolation when VCC = 0 V - prevents current backflow during system sleep or hot-plug scenarios. |
| Overvoltage-tolerant inputs | Accepts VIN up to 5.5 V regardless of VCC setting - simplifies level-shifting between 1.8 V, 3.3 V, and 5 V domains. |
| Low dynamic power | CPD = 11 pF at 5.5 V - limits no-load switching power to <1.5 mW at 10 MHz, ideal for battery-operated systems. |
| Pb-free & RoHS compliant | Meets J-STD-609 Category 1 moisture sensitivity (MSL 1) - supports standard reflow without baking or special handling. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Conditioning |

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 | Lower hysteresis (0.2 V typ at 3.3 V); no IOFF; 5-pin SOT-23 package (larger than SOT-553). | Lacks partial power-down protection; unsuitable for hot-swap or multi-rail sequencing. | Choose when board space is less constrained and IOFF is not required. |
| MC74VHC1G17DTT1G | Higher ICC (max 10 µA vs. 1 µA typ); same SOT-553 footprint; identical Schmitt thresholds at 5 V. | Higher quiescent current reduces battery life in always-on sensing nodes. | Prefer when sourcing from alternate distributors where NL17SZ17XV5T2G-L22087 is unavailable. |
Compared with SN74LVC1G17DBVR and MC74VHC1G17DTT1G, the NL17SZ17XV5T2G-L22087 offers superior noise immunity (0.7 V hysteresis), guaranteed IOFF behavior, and lowest input capacitance (2.5 pF), making it optimal for ultra-low-power, high-noise, and space-critical designs.

The NL17SZ17XV5T2G-L22087 supports DC input voltage up to 5.5 V regardless of VCC level - verified per datasheet Absolute Maximum Ratings table. This overvoltage tolerance allows safe interfacing with 5 V sources even when VCC is set to 1.8 V or 3.3 V, eliminating need for external clamping diodes.
Does NL17SZ17XV5T2G-L22087 support partial power-down mode?
Yes, NL17SZ17XV5T2G-L22087 features IOFF circuitry that disables both input and output paths when VCC = 0 V, limiting leakage current to ≤10 µA. This behavior is explicitly specified in the DC Electrical Characteristics table and ensures safe operation during power sequencing or hot-swap events.
What is the typical propagation delay of NL17SZ17XV5T2G-L22087 at 3.3 V supply?
At VCC = 3.3 V, RL = 1 MΩ, and CL = 15 pF, the NL17SZ17XV5T2G-L22087 exhibits 3.7 ns typical propagation delay (tPLH/tPHL), as confirmed in the AC Electrical Characteristics table. This value remains stable across −55 °C to +125 °C operating temperature range.
Is NL17SZ17XV5T2G-L22087 qualified for automotive applications?
The base NL17SZ17XV5T2G-L22087 is not automotive-qualified; however, its automotive-grade variant NL17SZ17XV5T2G-Q (with −Q suffix) is AEC-Q100 qualified and PPAP capable. The -Q version shares identical electrical specs and SOT-553 packaging but includes enhanced process controls and traceability for automotive use.
What is the pin 1 identifier for NL17SZ17XV5T2G-L22087 in SOT-553 package?
