SN74AUC1G14YEPR

Overview

The SN74AUC1G14YEPR is a single Schmitt-trigger inverter from the Texas Instruments AUC logic family, housed in a NanoFree DSBGA package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features a maximum propagation delay of 2.5 ns at 1.8 V and includes Ioff circuitry for partial-power-down applications. It provides latch-up protection exceeding 100 mA per JESD 78, Class II standards.

Feature Summary

• Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals to prevent noise-induced output transitions.
• Ioff circuitry disables outputs during partial-power-down mode to prevent damaging current backflow through the device.
• ESD protection capabilities exceed specified limits for human-body model, machine model, and charged-device model testing.

Applications

• AV Receiver
• Portable Audio Dock
• Blu-Ray Player and Home Theater
• Embedded PC
• Wireless Headset, Keyboard, and Mouse

Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum to confirm the exact package type and moisture sensitivity level. Confirm RoHS compliance status and lead finish details directly from the latest production data documentation before procurement.

Selection Notes

Select this component when designing circuits requiring noise immunity via Schmitt-trigger inputs in ultra-small form factors. Ensure the operating voltage aligns with the 0.8-V to 2.7-V range and verify that the 3.6-V I/O tolerance meets system interface requirements.

Part Context

This device belongs to the SN74AUC1G series of sub-1-V Little Logic devices designed for low-voltage portable electronics. The NanoFree packaging utilizes the die as the package to minimize footprint size, making it suitable for space-constrained mobile and consumer applications.

FAQ

What is the function of the Ioff circuitry in this device?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device during partial-power-down applications.

How does the Schmitt-trigger feature benefit signal integrity?

It provides different input threshold levels for positive-going (VT+) and negative-going (VT–) signals, which helps eliminate noise and prevents false triggering on slow or noisy input signals.
