Product details
Overview
NLV27WZ16DFT2G 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, overvoltage-tolerant inputs/outputs up to 5.5 V, and IOFF partial power-down protection - used in level-shifting and signal fanout within automotive body control modules.
For engineers reviewing the NLV27WZ16DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (1.65–5.5 V), output drive strength (32 mA sink at 4.5 V), tri-state compatibility, AEC-Q100 qualification, and SC-88 package footprint constraints.
Technical Context
The NLV27WZ16DFT2G implements two independent CMOS buffer stages with rail-to-rail input tolerance and active-low tri-state control per channel. Its IOFF feature disables current flow when VCC = 0 V, preventing back-driving in partial-power-down systems.
It supports mixed-voltage interfacing across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains due to input overvoltage tolerance up to 5.5 V and output swing from GND to VCC. Propagation delay scales inversely with supply voltage - 9.6 ns at 1.8 V, 2.9 ns at 5.5 V (RL = 1 MΩ, CL = 15 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V microcontrollers and 5 V legacy peripherals without level shifters. |
| Propagation Delay (tPD) | 2.4 ns at VCC = 5 V (typ) - supports high-speed signal buffering in timing-critical paths like sensor data routing. |
| Output Drive Strength | Sink 32 mA at 4.5 V - sufficient to drive multiple 74LVC inputs or small LED loads directly. |
| Input Overvoltage Tolerance | Up to 5.5 V regardless of VCC - allows safe connection to higher-voltage buses while powered from lower supplies. |
| IOFF Partial Power-Down | Active when VCC = 0 V - prevents current leakage between powered and unpowered sections in modular systems. |
| Operating Temperature | −55 °C to +125 °C - meets extended industrial and automotive under-hood requirements. |
| ESD Rating (HBM) | 2000 V - provides robust handling during board assembly and field service. |
Pinout & Package
Package: SC-88 (Case 419B-02), 6-pin, 2.00 mm × 1.25 mm × 0.90 mm, 0.65 mm pitch, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A2 (Input 2) | Second buffer input; accepts 0–5.5 V logic signals independent of VCC. |
| 2 | A1 (Input 1) | First buffer input; electrically isolated from A2, supports asynchronous signal routing. |
| 3 | GND | Ground reference for both buffers and internal circuitry; must be low-impedance for noise immunity. |
| 4 | VCC | Positive supply rail; powers both buffers and defines output logic-high level (VOH ≈ VCC − 0.1 V). |
| 5 | Y2 (Output 2) | Inverted-phase replica of A2; drives downstream loads with full rail-swing capability. |
| 6 | Y1 (Output 1) | Inverted-phase replica of A1; supports fanout to ≥10 LVC inputs at 5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Accepts 0–5.5 V inputs at any VCC from 1.65–5.5 V - eliminates external clamping diodes in mixed-supply systems. |
| IOFF power-off isolation | Blocks >99% of leakage current when VCC = 0 V - critical for hot-swap and modular power sequencing. |
| Low dynamic power | CPD = 11–12.5 pF - limits switching current to <10 μA at 10 MHz, reducing system-level power budget impact. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C) and PPAP-capable - validated for automotive body electronics and infotainment interfaces. |
| Small-footprint packaging | SC-88 occupies only 2.5 mm² PCB area - ideal for space-constrained ECUs and sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DCUR | 3-state enabled via OE pin; 32 mA drive at 3.3 V; no IOFF; max VCC = 3.6 V. | Limited to ≤3.6 V systems; requires external OE control; not AEC-Q100 qualified. | Choose for cost-sensitive consumer designs where 3.3 V-only operation and OE flexibility are prioritized. |
| MC74VHC1GT126DFR2G | Single-channel; push-pull output; 8 mA drive at 5 V; no IOFF; operates up to 5.5 V. | Requires two devices for dual functionality; lower drive strength; lacks automotive qualification. | Use when space permits duplication and lower output current suffices for light-load interfacing. |
Compared with SN74LVC2G126DCUR and MC74VHC1GT126DFR2G, the NLV27WZ16DFT2G uniquely combines dual-channel operation, 1.65–5.5 V universal supply, IOFF protection, and AEC-Q100 compliance - making it the only drop-in solution for automotive-grade mixed-voltage signal buffering without redesign.

FAQ
What is the maximum input voltage the NLV27WZ16DFT2G can tolerate regardless of supply voltage?
The NLV27WZ16DFT2G accepts DC input voltages up to 5.5 V on any input pin, independent of the VCC supply level - a key feature enabling safe interfacing with higher-voltage buses while operating from 1.65 V or 3.3 V supplies. This overvoltage tolerance is explicitly specified in the Absolute Maximum Ratings table and confirmed across all recommended operating conditions in the datasheet.
Does the NLV27WZ16DFT2G support tri-state operation?
No, the NLV27WZ16DFT2G does not provide tri-state (high-impedance) outputs. It is a dual non-inverting buffer with fixed push-pull outputs. Tri-state functionality is not included in its logic diagram, function table, or AC characteristics - unlike variants such as the NLV27WZ126 which integrate output-enable control. The NLV27WZ16DFT2G relies on IOFF for power-down isolation instead.
Is the NLV27WZ16DFT2G qualified for automotive applications?
Yes, the NLV27WZ16DFT2G is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient) and PPAP-capable, as confirmed in the datasheet's "Features" section and Ordering Information table. The "NLV" prefix denotes the automotive-qualified variant, distinct from the commercial-grade NL27WZ16, and includes enhanced reliability testing and traceable manufacturing controls.
What package type is used for the NLV27WZ16DFT2G?
The NLV27WZ16DFT2G uses the SC-88 package (Case 419B-02): a 6-pin, surface-mount, leadless package measuring 2.00 mm × 1.25 mm × 0.90 mm with 0.65 mm pitch. This is verified in the Ordering Information table, package dimensions section, and marking diagrams - and is distinct from SC-74 or UDFN6 variants of the same logic family.
How does the IOFF feature of the NLV27WZ16DFT2G improve system reliability?
The IOFF feature in the NLV27WZ16DFT2G disables current flow through the device when VCC = 0 V, limiting off-state leakage to ≤10 μA per pin. This prevents back-powering of unpowered subsystems - a critical requirement in modular architectures like automotive domain controllers where individual modules may be powered down independently while others remain active.
