onsemi NL27WZ86US

Overview

NL27WZ86US from onsemi is a dual 2-input exclusive-OR (XOR) gate IC operating from 1.65 V to 5.5 V, delivering 2.9 ns propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and overvoltage-tolerant inputs/outputs up to 5.5 V - used in digital logic level translation, parity generation, and configurable signal routing in automotive control modules.

For engineers reviewing the NL27WZ86US datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility (1.65–5.5 V), AEC-Q100 qualification for automotive use, US8 package footprint, and IOFF-enabled partial power-down protection in mixed-voltage systems.

Technical Context

The NL27WZ86US implements two independent XOR logic functions with true complementary outputs per gate, supporting rail-to-rail input operation across its full 1.65–5.5 V VCC range. Its IOFF circuitry disables output leakage when VCC = 0 V, enabling live insertion and hot-swap capability in backplane and modular systems.

It features overvoltage-tolerant I/O pins rated to 5.5 V regardless of VCC level, allowing interoperability between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. Propagation delay varies with supply voltage and load: 2.9 ns (typ) at 5 V/15 pF, 3.0 ns (typ) at 3.3 V/15 pF, and 4.1 ns (typ) at 2.5 V/15 pF.

FAQ

What is the maximum supply voltage rating for NL27WZ86US?

The NL27WZ86US supports a maximum DC supply voltage (VCC) of +6.5 V per the Absolute Maximum Ratings table. However, its recommended operating range is 1.65 V to 5.5 V. Operation above 5.5 V may cause permanent damage or accelerated wear, and is not guaranteed for functionality or reliability. The NL27WZ86US must not be operated continuously at 6.5 V - that value defines the absolute limit beyond which device failure is likely.

Does NL27WZ86US support partial power-down mode, and how is it implemented?

Yes, the NL27WZ86US supports partial power-down via its IOFF feature. When VCC = 0 V, all outputs enter a high-impedance state with leakage current ≤10 µA, preventing back-driving of powered sections in multi-rail systems. This behavior is intrinsic to the internal circuitry and requires no external control signals. The NL27WZ86US achieves this without additional biasing or configuration - it activates automatically upon VCC removal.

Is NL27WZ86US pin-compatible with other dual XOR gate packages like UQFN8?

No, the NL27WZ86US (US8 package) is not pin-compatible with the UQFN8 variant (NL27WZ86MQ1TCG). Pin assignments differ: US8 uses pin 1 = A1, pin 2 = B1, pin 3 = Y2, whereas UQFN8 uses pin 1 = Y1, pin 2 = B2, pin 3 = A2. Board layout must be redesigned when switching between these packages. The NL27WZ86US requires its specific US8 footprint and cannot be substituted with UQFN8 without PCB revision.

What is the typical propagation delay of NL27WZ86US at 3.3 V supply?

The typical propagation delay (tPLH/tPHL) of NL27WZ86US at 3.3 V supply and 15 pF load is 3.0 ns, as specified in the AC Electrical Characteristics table under "3.0 to 3.6 V" row. This value applies to both rising and falling edges and is measured under standard test conditions (CL = 15 pF, RL = 1 MΩ). The NL27WZ86US maintains consistent delay performance across temperature (−55 °C to +125 °C), with max delay of 5.2 ns over full range.

How does NL27WZ86US handle input voltages exceeding its VCC level?

The NL27WZ86US features overvoltage-tolerant inputs rated to −0.5 V to +6.5 V, meaning it safely accepts 5 V logic signals even when powered from 1.8 V or 2.5 V. This is achieved through internal clamping structures that prevent latch-up or damage. No external components are needed. The NL27WZ86US guarantees correct logic interpretation and output response under these conditions - verified per JEDEC JESD78 Class II latch-up testing and ESD qualification.
