SN74AUC1G17YZPR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G17YZPR is a single Schmitt-trigger buffer from Texas Instruments, operating within a supply voltage range of 0.8 V to 2.7 V and optimized for 1.65 V to 1.95 V applications. It features a maximum propagation delay of 2.4 ns at 1.8 V and supports ±8 mA output drive current at the same voltage. The device includes Ioff circuitry for partial power-down mode protection and offers ESD protection exceeding 2000 V via the human-body model. It is housed in a 5-pin DSBGA (NanoFree) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals to ensure noise immunity.
• Ioff circuitry disables outputs during partial power-down to prevent damaging backflow currents.
• ESD protection exceeds JESD 22 standards with ratings of 2000 V (HBM), 200 V (MM), and 1000 V (CDM).
• Latch-up performance exceeds 100 mA per JESD 78, Class II specifications.

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise systems
• Wireless peripherals including headsets, keyboards, and mice
• Embedded PC and personal digital assistant (PDA) systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix YZPR corresponds to the DSBGA package configuration required for your design. Confirm that the component status remains active or check for valid alternatives if discontinuation occurs. Ensure compliance with RoHS3 requirements and verify moisture sensitivity level ratings before assembly processing.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when mixed-mode signal operation is required due to its 3.6-V I/O tolerance despite sub-1-V operability. The NanoFree package is suitable for designs prioritizing minimal footprint. Consider the low static current consumption of 10 µA for battery-powered applications requiring extended operational life.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AUC1G series of Little Logic devices designed for sub-1-V operation. It performs the Boolean function Y = A using a single buffer element. The technology utilizes die-as-package concepts to achieve high density in a small form factor, distinguishing it from traditional plastic encapsulated logic families.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the purpose of the Ioff feature in this buffer?

The Ioff circuitry ensures that outputs are disabled when the device is powered down, preventing damaging current backflow through the device in partial-power-down applications.

How does the Schmitt-trigger input benefit signal integrity?

It provides different input threshold levels for positive-going (VT+) and negative-going (VT–) signals, which helps eliminate noise and glitches on slow-rising input waveforms.
