Product details
Overview
NLV17SZ125DFT1G from onsemi is a single non-inverting 3-state buffer IC designed for level-shifting and bus isolation in low-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers 2.3 ns typical propagation delay at 5 V, supports 24 mA output drive at 3.0 V, and features IOFF partial power-down protection. It is used in portable instrumentation data paths where voltage translation and tri-state control are required.
For engineers reviewing the NLV17SZ125DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility, 3-state enable timing (tPZH/tPHZ), input overvoltage tolerance up to 5.5 V, and SC-88A package footprint constraints.
Technical Context
The NLV17SZ125DFT1G implements a CMOS-based non-inverting buffer with active-low 3-state output control (OE). Its logic function is defined by a truth table where output Y follows input A when OE is low, and enters high-impedance state when OE is high.
It supports mixed-voltage interfacing due to input overvoltage tolerance up to 5.5 V independent of VCC, and includes IOFF circuitry that disables I/O leakage during power-down. Propagation delay varies with VCC and load: 4.5–4.8 ns (max) at 4.5–5.5 V with CL = 15 pF/RL = 1 MΩ.
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 |
| tPLH/tPHL (typ) | 2.3 ns at VCC = 5 V, CL = 15 pF - ensures sub-5 ns signal path latency in high-speed control lines |
| IOUT (sink/source) | ±24 mA at VCC = 3.0 V - drives standard TTL loads and multiple CMOS inputs without external buffering |
| Input Overvoltage | Up to 5.5 V - allows safe connection to higher-voltage buses without level shifters |
| IOFF Protection | Active when VCC = 0 V - prevents back-powering and signal contention during partial power-down |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets robustness requirements for automated assembly and field operation |
Pinout & Package
NLV17SZ125DFT1G is packaged in SC-88A (Case 419A-02), a 5-pin surface-mount package measuring 2.0 mm × 1.25 mm × 0.95 mm with 0.65 mm pitch. Pin 1 is marked with a dot or beveled edge per JEDEC MO-203.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-low control input; asserts high-impedance state on Y when high |
| 2 | A (Data Input) | Non-inverting input; passes through to Y when OE is low |
| 3 | GND | Ground reference for all internal circuitry and I/O |
| 4 | Y (Output) | Buffered non-inverting output; tri-stated when OE is high |
| 5 | VCC | Positive supply rail; powers internal logic and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 1.65–5.5 V operation supports legacy and next-gen logic families without redesign |
| Low propagation delay | 2.3 ns typical at 5 V enables use in <100 MHz clock distribution and control timing paths |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - eliminates need for external clamping diodes |
| IOFF partial power-down | Blocks current flow between powered and unpowered sections - critical for hot-swap and modular systems |
| AEC-Q100 qualified | Qualified for automotive applications (Grade 1: −40 °C to +125 °C ambient) with PPAP capability |

FAQ
What is the maximum input voltage the NLV17SZ125DFT1G can tolerate when VCC = 1.8 V?
The NLV17SZ125DFT1G supports input overvoltage tolerance up to 5.5 V regardless of VCC level. When VCC = 1.8 V, inputs may safely reach 5.5 V without damage or functional disruption - a key feature enabling direct interfacing with higher-voltage peripherals without external level shifters. This specification is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and reinforced in the Features section.
Does the NLV17SZ125DFT1G support partial power-down (IOFF) functionality?
Yes, the NLV17SZ125DFT1G includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. Per the datasheet, IOFF limits current to ≤10 µA (max) under power-off conditions, preventing back-powering of upstream or downstream circuits. This is explicitly documented in the DC Electrical Characteristics table under the IOFF parameter and highlighted in the Features list.
What is the pinout configuration for the NLV17SZ125DFT1G in its SC-88A package?
The NLV17SZ125DFT1G in SC-88A uses the standard pin assignment: Pin 1 = OE (active-low enable), Pin 2 = A (input), Pin 3 = GND, Pin 4 = Y (output), Pin 5 = VCC. This layout is shown in Figure 2 (top view) and verified in the Pin Assignment table on page 2 of the datasheet. Pin 1 is marked with a dot or bevel per JEDEC MO-203.
Is the NLV17SZ125DFT1G qualified for automotive applications?
Yes, the NLV17SZ125DFT1G carries the "-Q" suffix variant (e.g., NL17SZ125DFT1G-Q), which is AEC-Q100 qualified and PPAP capable. While the base part number NLV17SZ125DFT1G itself is the commercial-grade version, its design and process are derived from the automotive-qualified lineage, and the datasheet explicitly states "-Q Suffix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC-Q100 Qualified and PPAP Capable."
What is the typical propagation delay of the NLV17SZ125DFT1G at 3.3 V supply?
At VCC = 3.3 V with RL = 1 MΩ and CL = 15 pF, the NLV17SZ125DFT1G exhibits a typical propagation delay (tPLH/tPHL) of 2.5 ns, with a maximum of 5.2 ns over temperature. This value is specified in the AC Electrical Characteristics table on page 5 of the datasheet and reflects the device's performance in common 3.3 V logic systems.
