Product details
Overview
NL27WZ16DFT2G-L22348 from onsemi is a dual non-inverting buffer IC operating from 1.65 V to 5.5 V, delivering 2.4 ns propagation delay at 5 V, ±32 mA output drive, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a level-shifting and signal fan-out device in low-power digital logic interfaces, including portable instrumentation and industrial control I/O conditioning.
For engineers reviewing the NL27WZ16DFT2G-L22348 datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (1.65–5.5 V), IOFF partial power-down support, tri-state compatibility, SC-88 package footprint, and AEC-Q100 qualification status for automotive-grade designs.
Technical Context
The NL27WZ16DFT2G-L22348 implements two independent CMOS non-inverting buffers with rail-to-rail input tolerance and active-low tri-state control per channel. Its IOFF circuitry enables safe bus isolation during partial power-down, preventing back-drive current when VCC = 0 V.
It supports mixed-voltage system interfacing via 5.5 V-tolerant inputs while operating from as low as 1.65 V, and features low dynamic power consumption (CPD = 11–12.5 pF) and high-speed switching (tPLH/tPHL ≤ 2.9 ns at 5 V, CL = 15 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage 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 shifters. |
| Propagation Delay (tPD) | 2.4 ns (typ) at VCC = 5 V, CL = 15 pF - Supports >300 MHz signal routing in timing-critical paths. |
| Output Drive Strength | Sink/source up to 32 mA at 4.5 V - Drives multiple standard CMOS loads or small capacitive buses directly. |
| Input/Output Overvoltage Tolerance | Up to 5.5 V regardless of VCC - Allows hot-plug and mixed-supply interface without external clamping diodes. |
| IOFF Leakage Current | ≤10 µA at VCC = 0 V - Ensures zero-current path between powered and unpowered sections in modular systems. |
| Operating Temperature | −55 °C to +125 °C - Qualified for extended industrial and under-hood automotive environments. |
| ESD Rating (HBM) | 2000 V - Meets JEDEC JS-001-2017 for robust handling in automated assembly lines. |
Pinout & Package
Package: SC-88 (Case 419B-02), 6-pin, 2.00 mm × 1.25 mm × 0.90 mm body, 0.65 mm pitch, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A2 (Input 2) | Second independent logic input; accepts 0–5.5 V regardless of VCC value. |
| 2 | A1 (Input 1) | First independent logic input; fully overvoltage tolerant and compatible with 1.65–5.5 V supplies. |
| 3 | GND | Digital ground reference; must be connected to system ground plane for noise immunity and IOFF functionality. |
| 4 | VCC | Positive supply rail; powers both buffers and defines logic thresholds (VIH/VIL scale with VCC). |
| 5 | Y2 (Output 2) | Inverted-phase output of A2; drives loads with 32 mA sink capability and <0.55 V VOL at 32 mA. |
| 6 | Y1 (Output 1) | Inverted-phase output of A1; electrically identical to Y2 and supports tri-state behavior when enabled. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operation (1.65–5.5 V) | Eliminates need for separate level translators in multi-rail systems such as USB-C PD controllers or sensor hubs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DBVR | 3.6 V max VCC; no IOFF; 3.5 ns tPD at 3.3 V; 24 mA drive | Lacks partial power-down protection and 5.5 V tolerance; unsuitable for hot-swap or mixed-voltage isolation | Select only for cost-sensitive 3.3 V-only systems where IOFF and overvoltage tolerance are not required. |
| 74AUP2G126GW,125 | 0.8–3.6 V VCC; 3.8 ns tPD at 3.3 V; 20 mA drive; IOFF supported | Lower max VCC limits use in 5 V legacy interfaces; higher propagation delay affects timing margins in high-speed links | Prefer for ultra-low-power battery applications needing sub-1 µA ICCQ, but verify 5 V signal compatibility separately. |
Compared with SN74LVC2G126DBVR and 74AUP2G126GW,125, the NL27WZ16DFT2G-L22348 uniquely combines 5.5 V I/O tolerance, IOFF, and sub-3 ns speed across 1.65–5.5 V operation-making it the only choice for robust, mixed-voltage industrial and automotive buffer applications requiring guaranteed hot-swap safety and timing performance.

FAQ
What is the maximum input voltage the NL27WZ16DFT2G-L22348 can tolerate?
The NL27WZ16DFT2G-L22348 supports DC input voltages up to 5.5 V regardless of VCC level, enabling direct interfacing with 5 V logic or analog signals even when powered from 1.65 V. This overvoltage tolerance eliminates external clamping diodes in mixed-supply systems and is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V, with functional operation up to +5.5 V).
Does the NL27WZ16DFT2G-L22348 support tri-state operation?
No, the NL27WZ16DFT2G-L22348 does not feature an enable pin or internal tri-state control. It is a dual non-inverting buffer with fixed output states determined solely by its A1 and A2 inputs. Tri-state functionality is absent per the Function Table and Pin Assignment diagrams in the datasheet-only high/low output states are defined.
Is the NL27WZ16DFT2G-L22348 qualified for automotive applications?
Yes, the NL27WZ16DFT2G-L22348 is AEC-Q100 qualified (Grade 1, −40 °C to +125 °C ambient) and PPAP capable. The "−Q" suffix variant (e.g., NL27WZ16DFT2G−Q) explicitly denotes automotive qualification, and the base NL27WZ16DFT2G shares identical die and process-confirmed in the Ordering Information section and Features list.
What package type is used for the NL27WZ16DFT2G-L22348?
The NL27WZ16DFT2G-L22348 uses the SC-88 (Case 419B-02) package: a 6-pin, surface-mount, leadless plastic package measuring 2.00 mm × 1.25 mm × 0.90 mm with 0.65 mm pitch. This is verified in the Ordering Information table, where "NL27WZ16DFT2G" maps exclusively to SC-88 with "MR" marking code and "Q4" pin-1 orientation.
How does IOFF functionality work in the NL27WZ16DFT2G-L22348?
IOFF in the NL27WZ16DFT2G-L22348 disables the output FETs when VCC = 0 V, limiting input/output leakage to ≤10 µA. This prevents current flow between powered and unpowered sections-critical for hot-swap and modular systems. The feature is inherent to the design and requires no external control; it activates automatically during power-down, as specified in the DC Electrical Characteristics table under IOFF parameter.
