SN74AUC1G14DBVRG4

Overview

The SN74AUC1G14DBVRG4 is a single Schmitt-trigger inverter from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V, with specific optimization for 1.65 V to 1.95 V applications. The device features distinct positive-going (VT+) and negative-going (VT–) input threshold levels to provide noise immunity. It supports partial-power-down mode via Ioff circuitry to prevent backflow current. The component is housed in a 5-pin SOT-23 package.

Feature Summary

• Schmitt-trigger action provides different input thresholds for rising and falling signals to enhance noise rejection.
• Ioff circuitry enables partial-power-down operation by disabling outputs to prevent damaging current backflow.
• ESD protection ratings exceed JESD 22 standards for human-body, machine model, and charged-device models.

Applications

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise systems
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify that the ordering suffix 'G4' corresponds to the specific lead finish and environmental compliance requirements defined in the manufacturer's documentation. Confirm the package type matches the design footprint. Ensure the supply voltage constraints align with the system power rails before integration.

Selection Notes

Select this component when sub-1-V operation or mixed-mode signal compatibility is required. The device is designed specifically for 1.8-V operation while maintaining 3.6-V I/O tolerance. Consider the NanoFree™ packaging technology if minimal board space is a constraint, although this specific part uses SOT-23.

Part Context

This device belongs to the SN74AUC1G series of Little Logic devices. It implements the Boolean function Y = A using CMOS technology. The AUC series is characterized by high speed and low power consumption, suitable for portable and battery-operated electronics requiring efficient signal inversion.
