Product details
Overview
NL17SZ16DFT2G-L22038 from onsemi is a single-channel CMOS buffer IC in SC-88A (SOT-353) package, operating from 1.65 V to 5.5 V supply, delivering 2.4 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and overvoltage-tolerant inputs/outputs up to 5.5 V - used for level-shifting and signal conditioning in space-constrained industrial control interfaces.
For engineers reviewing the NL17SZ16DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility, output drive strength at target VCC, tri-state enable behavior, IOFF partial power-down support, and SC-88A footprint constraints in high-density PCB layouts.
Technical Context
The NL17SZ16DFT2G-L22038 implements a non-inverting digital buffer with true CMOS input structure and push-pull output stage. It supports full rail-to-rail input voltage tolerance (−0.5 V to VCC + 0.5 V) and operates across −55 °C to +125 °C ambient temperature.
Its IOFF feature disables current flow between powered and unpowered sections when VCC = 0 V, preventing back-drive damage in partial-power-down systems. The device exhibits no internal pull-ups or pull-downs, requiring external termination where needed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level translators. |
| tPD (Typ) | 2.4 ns at VCC = 5 V, CL = 15 pF - supports >200 MHz signal integrity in short-path buffering applications. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - drives multiple standard CMOS loads or low-impedance traces without external buffers. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage peripherals even when VCC = 1.8 V. |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents cross-talk and bus contention during hot-swap or power sequencing events. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor telecom equipment. |
Pinout & Package
Package: SC-88A (SOT-353), 5-pin, 2.0 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must be left floating or tied to GND per layout best practice; no electrical function. |
| 2 | Input (A) | Digital input node accepting CMOS-compatible signals; tolerant to 5.5 V regardless of VCC setting. |
| 3 | GND | Ground reference for all internal circuitry and output return path; requires low-impedance connection to system ground plane. |
| 4 | Output (Y) | Push-pull CMOS output driving high/low states; supports tri-state behavior only when VCC = 0 V (via IOFF). |
| 5 | VCC | Positive supply input; decoupling capacitor (0.1 µF ceramic) required within 2 mm of this pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC Range | 1.65–5.5 V operation enables single-bom reuse across multiple voltage domains in mixed-supply systems. |
| Overvoltage-Tolerant I/O | Inputs and outputs withstand up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interconnects. |
| IOFF Partial Power-Down | Blocks current flow between powered and unpowered sections when VCC = 0 V - critical for hot-plug and modular backplane designs. |
| Low Propagation Delay | 2.4 ns typical tPD at 5 V ensures minimal timing skew in clock distribution, data strobe, or enable signal paths. |
| Small Footprint | SC-88A package occupies only 2.5 mm² board area - ideal for wearables, sensor nodes, and ultra-compact modules. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Includes Schmitt-trigger input hysteresis (350 mV typ); no IOFF; same SC-70-5 package. | Better noise immunity in slow-rising or noisy environments; unsuitable for partial power-down isolation. | Select when input signal edges are slow or noisy; avoid if hot-swap or power sequencing isolation is required. |
| 74LVC1G07GW,125 | Open-drain output; requires external pull-up; supports 1.65–5.5 V; same SOT-353 footprint. | Enables wired-OR logic and multi-master bus driving; lacks push-pull drive and IOFF. | Select for I²C/SMBus buffering or shared interrupt lines; not suitable for driving capacitive loads directly. |
Compared with SN74LVC1G17DBVR and 74LVC1G07GW,125, the NL17SZ16DFT2G-L22038 uniquely combines push-pull drive, overvoltage tolerance, and IOFF - making it optimal for mixed-voltage signal routing where power domain isolation and clean edge fidelity are both required.

FAQ
What is the maximum input voltage rating for NL17SZ16DFT2G-L22038 when VCC = 1.8 V?
The NL17SZ16DFT2G-L22038 supports DC input voltages up to 5.5 V regardless of VCC setting, including at 1.8 V operation. This overvoltage tolerance eliminates external clamping diodes when interfacing with higher-voltage peripherals, and is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and Functional Characteristics section of the datasheet.
Does NL17SZ16DFT2G-L22038 support true tri-state output control?
No, the NL17SZ16DFT2G-L22038 does not implement active tri-state control via an enable pin. Its output remains functional whenever VCC is powered. However, the IOFF feature activates automatically when VCC = 0 V, blocking current flow and effectively isolating the output - a passive form of power-down isolation, not user-controllable tri-state.
What is the recommended PCB pad layout for the SC-88A package of NL17SZ16DFT2G-L22038?
For NL17SZ16DFT2G-L22038 in SC-88A (Case 419A-02), use IPC-7351B "SOT-353" land pattern: 0.65 mm pitch, 0.45 mm × 0.95 mm pads, 0.25 mm solder mask opening, and thermal relief for Pin 3 (GND) and Pin 5 (VCC). Avoid solder bridging by maintaining ≥0.15 mm solder mask web between pins 1–2 and 4–5.
Can NL17SZ16DFT2G-L22038 drive a 50 pF capacitive load at 10 MHz without signal degradation?
Yes - the NL17SZ16DFT2G-L22038 delivers 2.9 ns typical tPLH/tPHL into 50 pF at VCC = 4.5–5.5 V (AC Electrical Characteristics table), with <2.5 pF input/output capacitance minimizing loading effects. At 10 MHz, its CPD = 11 pF ensures dynamic power remains below 0.5 mW, supporting clean edge integrity across full-speed USB or SPI control lines.
Is NL17SZ16DFT2G-L22038 qualified for automotive AEC-Q100 stress testing?
No - the NL17SZ16DFT2G-L22038 is not AEC-Q100 qualified. It is rated for −55 °C to +125 °C operating temperature and meets JEDEC JESD22-A114 reliability standards, but lacks automotive-specific qualification. For automotive applications, onsemi recommends the AEC-Q100 qualified NL17SZ16DMR2G (SC-74A-5) or NL17SZ16XV5T2G (SOT-553-5) variants.
