Product details
Overview
NLV27WZ17DFT2G from onsemi is a dual non-inverting Schmitt-trigger buffer IC designed for noise-immune signal conditioning in automotive and industrial systems, operating from 1.65 V to 5.5 V, delivering 3.7 ns typical propagation delay at 5 V, ±32 mA output drive, and overvoltage-tolerant inputs/outputs up to 5.5 V.
For engineers reviewing the NLV27WZ17DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include Schmitt-trigger hysteresis (0.7 V min at 3 V), AEC-Q100 qualification, IOFF partial power-down support, and SC-88 package compatibility with space-constrained PCB layouts.
Technical Context
The NLV27WZ17DFT2G integrates two independent non-inverting Schmitt-trigger buffers with input hysteresis (VH = 0.48 V typ at 2.3 V) to reject noise on slow or noisy digital signals. Each channel features rail-to-rail input tolerance and supports tri-state operation via power-down mode when VCC = 0 V.
Its IOFF circuitry prevents current backflow during partial power-down, enabling safe hot-insertion in multi-rail systems. The device meets AEC-Q100 Grade 1 (−40°C to +125°C) and is Pb-free, halogen-free, and RoHS compliant - confirming suitability for automotive body electronics and under-hood control modules.
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) | 3.7 ns typ at VCC = 5 V - supports high-speed signal re-timing in clock distribution and data path conditioning |
| Input Hysteresis (VH) | 0.48 V typ at 2.3 V - provides robust noise margin against EMI-induced glitches in automotive harness environments |
| Output Drive Strength | Sink 32 mA at 4.5 V - sufficient to directly drive LEDs, small relays, or multiple CMOS loads without external buffers |
| IOFF Leakage Current | ≤10 µA max - ensures no signal coupling between powered and unpowered sections in modular subsystems |
| Operating Temperature | −55°C to +125°C - validated for engine control units, transmission controllers, and ADAS sensor interfaces |
| ESD Rating (HBM) | 2000 V - exceeds IEC 61000-4-2 Level 2 requirements for board-level transient immunity |
Pinout & Package
Package: SC-88 (Case 419B-02), 6-pin, 2.00 mm × 1.25 mm × 0.90 mm, 0.65 mm pitch, surface-mount, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A2 (Input Channel 2) | Dedicated Schmitt-trigger input for second buffer; tolerant to 5.5 V regardless of VCC |
| 2 | A1 (Input Channel 1) | Dedicated Schmitt-trigger input for first buffer; enables independent noise filtering of two signals |
| 3 | GND | Ground reference for both channels and internal biasing; must be low-impedance for stable hysteresis |
| 4 | VCC | Positive supply rail; powers both buffers and sets input/output voltage thresholds |
| 5 | Y2 (Output Channel 2) | Non-inverting buffered output with 32 mA sink capability; compatible with 5 V TTL and 3.3 V CMOS loads |
| 6 | Y1 (Output Channel 1) | Non-inverting buffered output; electrically isolated from Y2 - no crosstalk between channels |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs with programmable hysteresis | Hysteresis voltage (VH) ranges from 0.48 V (2.3 V) to 1.4 V (5.5 V), enabling adaptive noise rejection per supply condition |
| Overvoltage-tolerant I/O | Inputs and outputs withstand up to 5.5 V independent of VCC - eliminates need for external clamping diodes in mixed-voltage systems |
| IOFF partial power-down protection | Blocks current flow between powered and unpowered rails during system sleep modes - critical for gateway ECUs with domain wake-up |
| AEC-Q100 qualified (Grade 1) | Validated for automotive applications requiring −40°C to +125°C operation and PPAP compliance - suitable for ASIL-B supporting functions |
| Low dynamic power consumption | CPD = 12.5 pF at 5 V - limits switching current to <1 µA/MHz, reducing thermal load in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC14DT | Hex inverting Schmitt trigger, 2.0 V–5.5 V, tPD = 7.5 ns @ 5 V, no IOFF, SOIC-14 package | Requires external inverters for non-inverting function; larger footprint and higher quiescent current (ICC = 2 µA vs. 1 µA) | Choose when hex-channel count outweighs size/power constraints and inversion is acceptable |
| SN74LVC1G17DBVR | Single non-inverting Schmitt trigger, 1.65 V–5.5 V, tPD = 4.5 ns @ 3.3 V, no IOFF, SOT-23-5 package | Single-channel only; lacks dual-channel integration and AEC-Q100 qualification for automotive use | Choose for cost-sensitive consumer designs where dual-channel consolidation isn't required |
Compared with MC74VHC14DT and SN74LVC1G17DBVR, the NLV27WZ17DFT2G uniquely combines dual non-inverting topology, AEC-Q100 Grade 1 rating, IOFF protection, and SC-88 footprint - making it the only drop-in solution for space-constrained, safety-aware automotive signal conditioning where channel pairing and partial power-down are mandatory.

FAQ
What is the maximum input voltage the NLV27WZ17DFT2G can tolerate?
The NLV27WZ17DFT2G accepts DC input voltages up to 5.5 V regardless of VCC level - a feature confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +7.0 V, but functional operation limited to 5.5 V). This overvoltage tolerance eliminates external clamping components when interfacing with 5 V signals in 3.3 V or 1.8 V systems, and is fully supported across the full −55°C to +125°C operating range.
Does the NLV27WZ17DFT2G support partial power-down operation?
Yes, the NLV27WZ17DFT2G implements IOFF circuitry that disables current paths between inputs and outputs when VCC = 0 V, limiting leakage to ≤10 µA. This behavior is explicitly verified in the DC Electrical Characteristics table under IOFF test conditions and enables safe hot-plug operation in modular automotive ECUs where subsystems power up/down independently - a requirement for modern domain controller architectures.
Is the NLV27WZ17DFT2G qualified for automotive applications?
Yes, the NLV27WZ17DFT2G carries the NLV prefix indicating AEC-Q100 qualification (Grade 1: −40°C to +125°C ambient), PPAP capability, and unique site/control change requirements per onsemi's automotive product definition. Its qualification status is documented in the Features section and Ordering Information table - confirming suitability for body electronics, lighting, and chassis control modules in production vehicles.
What is the typical propagation delay of the NLV27WZ17DFT2G at 3.3 V supply?
At VCC = 3.3 V and TA = 25°C, the NLV27WZ17DFT2G exhibits a typical propagation delay (tPLH/tPHL) of 3.7 ns with RL = 1 MΩ and CL = 15 pF, as specified in the AC Electrical Characteristics table. This value remains within 6.5 ns max across the full −40°C to +85°C range - ensuring deterministic timing for real-time signal conditioning in engine control and ADAS pre-processing stages.
Can the NLV27WZ17DFT2G drive standard 5 V TTL loads?
Yes, the NLV27WZ17DFT2G can directly drive 5 V TTL loads: its VOL is ≤0.24 V at IOL = 4 mA and VCC = 1.65 V, and VOH reaches ≥3.8 V at IOH = −32 mA and VCC = 4.5 V - exceeding TTL VIH (2.0 V) and VIL (0.8 V) thresholds. This capability is validated across all recommended VCC ranges and eliminates the need for external level translators in mixed-voltage automotive gateways.
