NL27WZ14DFT2G-Q

Overview

The NL27WZ14DFT2G-Q is a dual Schmitt-trigger inverter from onsemi, designed for operation within a 1.65 V to 5.5 V supply range. It features inputs and outputs overvoltage tolerant up to 5.5 V and supports partial power down protection via IOFF. The device provides a typical propagation delay of 3.2 ns at 5 V and can sink 32 mA at 4.5 V. It is available in SC-88 packages and meets AEC-Q100 qualification standards with PPAP capability.

Feature Summary

• Dual Schmitt-trigger inverters with hysteresis for noise immunity
• Inputs and outputs tolerant to 5.5 V overvoltage
• Supports partial power down protection through IOFF feature
• Qualified for automotive applications under AEC-Q100

Applications

• Automotive electronic systems requiring unique site control
• Interfaces between different voltage logic domains
• Signal conditioning for noisy environments
• General-purpose digital logic inversion

Procurement Notes

Verify the -Q suffix indicates AEC-Q100 qualification and PPAP capability. Confirm the SC-88 package type matches design requirements. Ensure compliance with RoHS and halogen-free specifications. Check for specific manufacturing site constraints associated with the automotive grade designation.

Selection Notes

Select this component when Schmitt-trigger action is required for signal integrity. Consider the 1.65 V to 5.5 V operating range for compatibility with various logic families. The overvoltage tolerance allows interfacing with 5 V systems even at lower supply voltages. Verify thermal resistance values if high power dissipation is expected.

Part Context

This part belongs to the NL27WZ14 series of dual inverters. It is an automotive-grade version of the standard NL27WZ14DFT2G, distinguished by the -Q suffix which denotes specific manufacturing controls and qualification standards suitable for automotive environments.

Replacement Considerations

NL27WZ14DFT2G is the non-automotive equivalent. Other NL27WZ series devices may offer similar functionality but without the -Q automotive qualifications.
