NLU3G14AMX1TCG

Overview

The NLU3G14AMX1TCG is a triple Schmitt-trigger inverter from the MiniGate family, manufactured by onsemi. It utilizes advanced high-speed CMOS technology within an ultra-small UDFN8 footprint. The device operates with a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 7.0 V regardless of the supply level. Key electrical characteristics include a typical propagation delay of 4.0 ns at 5.0 V and a maximum quiescent current of 1 µA at 25°C.

Feature Summary

• Triple Schmitt-trigger inverter configuration for enhanced noise immunity
• Overvoltage tolerant (OVT) input and output pins providing protection up to 7.0 V
• Power down protection provided on inputs to minimize leakage during standby
• Balanced propagation delays ensuring consistent signal timing across channels

Applications

• Squaring up slowly changing waveforms
• Enhancing noise immunity in digital circuits
• Signal conditioning for microcontroller interfaces

Procurement Notes

Verify the specific package variant required, as the NLU3G14 series includes multiple UDFN8 options with different dimensions such as 1.45x1.0 mm, 1.6x1.0 mm, and 1.95x1.0 mm. Confirm that the AMX1TCG suffix corresponds to the exact pin pitch and footprint needed for your PCB layout. Ensure compliance with RoHS standards as these are lead-free devices.

Selection Notes

Select this component when space constraints require an ultra-small footprint alongside robust noise rejection capabilities. The overvoltage tolerance makes it suitable for interfacing between logic families with different voltage levels without external protection components. Consider the low power dissipation for battery-operated applications requiring minimal standby current consumption.

Part Context

This part belongs to the NLU3G14 MiniGate series, designed for portable and space-sensitive electronics. It represents an evolution in small-form-factor logic gates, offering high speed and low power in packages significantly smaller than traditional SOIC or DIP alternatives. The series is widely used in mobile devices and consumer electronics where board real estate is critical.

Replacement Considerations

Direct replacements must match the triple inverter function, UDFN8 package type, and voltage tolerances. Verify if alternative manufacturers offer equivalent OVT features and similar propagation delays. Check for pin compatibility and ensure the substitute device meets the same operating temperature range of -55°C to +125°C.
