NL37WZ14USG-Q

Overview

The NL37WZ14USG-Q is a high-performance triple inverter with Schmitt-Trigger inputs operating from a 1.65 V to 5.5 V supply. It features overvoltage-tolerant inputs and outputs up to 5.5 V, IOFF supporting partial power-down protection, and source/sink capabilities of 24 mA at 3.0 V. The device operates within an ambient temperature range of -55 °C to +125 °C and is available in the US8 package.

Feature Summary

• Triple inverter configuration with Schmitt-Trigger inputs for noise immunity
• IOFF feature supports partial power-down protection
• Inputs and outputs tolerant to voltages up to 5.5 V
• AEC-Q100 qualified and PPAP capable for automotive applications

Applications

• Automotive electronic systems requiring unique site and control change requirements
• Interfaces between 5 V TTL logic and lower voltage CMOS devices
• Applications requiring signal conditioning for slow input signals

Procurement Notes

Verify that the specific part number includes the '-Q' suffix to ensure AEC-Q100 qualification and PPAP capability. Confirm the package type matches the required footprint. Check the manufacturer's documentation for current RoHS compliance status and lead-free indicators before finalizing procurement specifications.

Selection Notes

Select this component when a triple inverter with Schmitt-trigger functionality is needed for noisy environments. Ensure the system voltage falls within the 1.65 V to 5.5 V range. Consider the US8 package dimensions for PCB layout. Verify thermal dissipation requirements if operating near maximum junction temperatures.

Part Context

This component belongs to the NL37WZ series of ultra-high-speed CMOS logic devices. It shares functional similarities with the NL37WZ04 but adds hysteresis via Schmitt triggers. The '-Q' suffix distinguishes it as an automotive-grade variant meeting stricter quality and manufacturing controls compared to commercial versions.
